what are the specific requirements for precision machinery parts processing?
1. Material Strength and Durability
One of the key requirements of precision machinery parts processing is material strength and durability.Machinery parts often undergo significant stress and pressure during operation, and the selected materials must be able to withstand these forces without deforming or breaking.For example, aerospace components require materials with high strength-to-weight ratios, such as titanium alloys, to ensure structural integrity and reliability.
2. Dimensional Stability
Precision machinery parts must maintain their dimensional stability even under extreme operating conditions.The materials used in their processing should possess low thermal expansion coefficients, allowing the parts to retain their shape and size without warping or distorting due to temperature fluctuations.Steels with low thermal expansion coefficients, such as tool steel or stainless steel, are commonly preferred for precision machinery parts subjected to varying thermal conditions.
3.Wear and Corrosion Resistance
Precision machinery parts often interact with other components or environments that can cause wear and corrosion.The materials chosen for their processing should exhibit excellent wear resistance to withstand constant friction and minimize surface damage.Additionally, corrosion resistance is crucial to ensure the longevity of the parts, especially in industries where exposure to moisture, chemicals, or harsh environments is common.Materials such as hardened steel, stainless steel, or certain grades of aluminum alloys are frequently utilized to enhance wear and corrosion resistance.
4.Machinability
Efficient and precise machining is a critical factor in the manufacturing of precision machinery parts.The material selected for processing should possess good machinability, allowing it to be easily cut, drilled, or shaped into the desired form with minimal tool wear.Materials like aluminum alloys with excellent machinability properties are often preferred for their versatility and ease of shaping into complex geometries.
5.Thermal Conductivity
Thermal management is significant in precision machinery parts processing, as excessive heat can adversely affect performance and increase the risk of failure.Materials with high thermal conductivity, such as copper alloys or certain grades of aluminum, help dissipate heat efficiently, preventing localized temperature rise and ensuring optimal operating conditions.
6.Cost-Effectiveness
While meeting the specific requirements is crucial, cost-effectiveness is also an important consideration in precision machinery parts processing.The selected materials should strike a balance between performance and cost, ensuring that the final product remains economically viable without compromising quality.Conducting a cost-benefit analysis and considering factors like material availability, processing complexity, and overall project budget can aid in making informed decisions regarding material selection.

reasons why stainless steel material affects the machining accuracy of parts
Precision parts processed with stainless steel have the advantages of corrosion resistance, long service life and good mechanical and dimensional stability, and austenitic stainless steel precision parts have been widely used in medical, instrumentation and other precision machinery fields.
The reasons why stainless steel material affects the machining accuracy of parts
The exceptional strength of stainless steel, coupled with its impressive plasticity and noticeable work hardening phenomenon, result in a significant disparity in cutting force when compared to carbon steel. In fact, the cutting force required for stainless steel surpasses that of carbon steel by more than 25%.
At the same time, the thermal conductivity of stainless steel is only one-third of that of carbon steel, and the cutting process temperature is high, which makes the milling process deteriorate.
The growing machining hardening trend observed in stainless steel materials demands our serious attention. During milling, the intermittent cutting process leads to excessive impact and vibration, resulting in substantial wear and collapse of the milling cutter. Furthermore, the use of small-diameter end milling cutters poses a higher risk of breakage. Significantly, the decrease in tool durability during the milling process adversely affects the surface roughness and dimensional accuracy of precision parts machined from stainless steel materials, rendering them unable to meet the required standards.
Stainless steel precision parts processing precision solutions
In the past, traditional machine tools had limited success in machining stainless steel parts, particularly when it came to small precision components. This posed a major challenge for manufacturers. However, the emergence of CNC machining technology has revolutionized the machining process. With the aid of advanced ceramic and alloy coating tools, CNC machining has successfully taken on the complex task of processing numerous stainless steel precision parts.

In the field of machining, after CNC machining process methods and division of processes, the main content of the process route is to rationally arrange these processing methods and processing sequence. In general, CNC machining of mechanical parts includes cutting, heat treatment and auxiliary processes such as surface treatment, cleaning and inspection. The sequence of these processes directly affects the quality, production efficiency and cost of the parts. Therefore, when designing CNC machining routes, the order of cutting, heat treatment and auxiliary processes should be reasonably arranged, and the connection problem between them should be solved.
In addition to the basic steps mentioned above, factors such as material selection, fixture design and equipment selection need to be considered when developing a CNC machining route. Material selection is directly related to the final performance of parts, different materials have different requirements for cutting parameters; The fixture design will affect the stability and accuracy of the parts in the process of processing; Equipment selection needs to determine the type of machine tool suitable for its production needs according to the characteristics of the product.
What do we have to do before arranging the CNC machining process route?
1, the processing method of precision machinery parts should be determined according to the characteristics of the surface. On the basis of familiar with the characteristics of various processing methods, mastering the processing economy and surface roughness, the method that can ensure the processing quality, production efficiency and economy is selected.
2, select the appropriate drawing positioning reference, according to the principle of crude and fine reference selection to reasonably determine the positioning reference of each process.
3, When developing the machining process route of the parts, it is necessary to divide the rough, semi-fine and finishing stages of the parts on the basis of the analysis of the parts, and determine the degree of concentration and dispersion of the process, and reasonably arrange the processing sequence of the surfaces. For complex parts, several schemes can be considered first, and the most reasonable processing scheme can be selected after comparison and analysis.
4, determine the processing allowance and process size and tolerance of each process.
5, select machine tools and workers, clips, quantities, cutting tools. The selection of mechanical equipment should not only ensure the quality of processing, but also be economical and reasonable. Under the conditions of mass production, general machine tools and special jigs should generally be used.
6, Determine the technical requirements and inspection methods of each major process.Determining the cutting amount and time quota of each process is usually decided by the operator for a single small batch production plant. It is generally not specified in the machining process card. However, in the medium batch and mass production plants, in order to ensure the rationality of production and the balance of rhythm, it is required that the cutting amount must be specified, and must not be changed at will.
cnc machining process arrangement
First rough and then fine
The processing accuracy is gradually improved according to the order of rough turning - semi-fine turning - fine turning. The rough lathe can remove most of the machining allowance of the workpiece surface in a short time, thereby increasing the metal removal rate and meeting the requirement of the uniformity of the allowance. If the residual amount left after the rough turning does not meet the finishing requirements, it is necessary to arrange a semi-finishing car for finishing. The fine car needs to ensure that the outline of the part is cut according to the drawing size to ensure the processing accuracy.
Approach first and then far
Under normal circumstances, the parts close to the tool should be processed first, and then the parts far away from the tool to the tool should be processed to shorten the moving distance of the tool and reduce the empty travel time. In the process of turning, it is beneficial to maintain the stiffness of the blank or semi-finished product and improve its cutting conditions.
The principle of internal and external intersection
For parts that have both an inner surface (inner cavity) and an outer surface to be processed, when arranging the processing sequence, the inner and outer surfaces should be roughed first, and then the inner and outer surfaces should be finished. Must not be part of the surface of the part (outer surface or inner surface) after processing, then processing other surfaces (inner surface or outer surface).
Base first principle
Priority should be given to the surface used as the finishing reference. This is because the more accurate the surface of the positioning reference, the smaller the clamping error. For example, when machining shaft parts, the center hole is usually machined first, and then the outer surface and end face are machined with the center hole as the precision basis.
The principle of the first and the second
The main working surface and assembly base surface of the parts should be processed first, so as to find out the modern defects on the main surface in the blank early. The secondary surface can be interspersed, placed on the main machined surface to a certain extent, before the final finishing.
The principle of the face before the hole
The plane outline size of the box and bracket parts is large, and the plane is generally processed first, and then the hole and other sizes are processed. This arrangement of processing sequence, on the one hand with the processed plane positioning, stable and reliable; On the other hand, it is easy to process the hole on the machined plane, and can improve the processing accuracy of the hole, especially when drilling, the axis of the hole is not easy to deviate.
Conclusion
When developing the machining process of parts, it is necessary to select the appropriate processing method, machine tool equipment, clamp measuring tools, blank and technical requirements for workers according to the production type of parts.
In addition to the basic steps mentioned above, factors such as material selection, fixture design and equipment selection need to be considered when developing a CNC machining route. Material selection is directly related to the final performance of parts, different materials have different requirements for cutting parameters; The fixture design will affect the stability and accuracy of the parts in the process of processing; Equipment selection needs to determine the type of machine tool suitable for its production needs according to the characteristics of the product.

With the increasingly updated processing technology, CNC machining has also undergone a lot of changes. Many experts pointed out that in the future, CNC will be the mainstream processing mode. In the CNC machining process, the tool is the most important, today, we will understand the CNC tool in detail.
CNC machining tool concept
A tool is a tool used for cutting in mechanical manufacturing. Generalized cutting tools include both cutting tools and abrasive tools. The vast majority of knives are used for machines, but there are also hand tools. Since the tools used in mechanical manufacturing are basically used to cut metal materials, the term "tool" is generally understood as a metal cutting tool. The cutting tools used for cutting wood are called woodworking tools.
CNC machining tool
Tool classification
Cutting tools can be divided into five categories according to the form of the workpiece machined surface.
Cutting tools for processing various outer surfaces, including cutting tools for processing various outer surfaces, including turning tools, planing knives, milling cutters, outer surface broach and file, etc.
Hole processing tools, including drill, reaming drill, boring cutter, milling cutter and internal surface broach, etc.
Thread processing tools, including tap, die, automatic opening thread cutting head, thread turning tool and thread milling cutter.
Gear processing tools, including hob, gear shaper cutter, shaving cutter, bevel gear processing tool, etc.
Cutting tools, including inserted circular saw blade, band saw, bow saw, cutting tool and saw blade milling cutter, etc.
In addition, there are combination tools.
Hole cutting tool
Tool structure
The structure of various tools is composed of a clamping part and a working part. The clamping part and working part of the overall structure of the tool are done on the tool body; The working part of the tool (the tooth or blade) is mounted on the tool body.
The clamping part of the tool has two kinds of holes and handles. The tool with hole relies on the inner hole set on the spindle or mandrel of the machine tool, and transmits the torsional torque with the help of the axial key or the end key, such as the cylindrical milling cutter and the sleeve face milling cutter.
The tool with the handle is usually rectangular handle, cylindrical handle and conical handle three kinds. Turning tools, planing tools, etc. are generally rectangular handles; The conical handle withstands the axial thrust with the taper and transmits the torque with the help of friction. Cylindrical shank is generally suitable for smaller twist drill, end mill and other tools, cutting with the help of the friction generated when clamping torque transfer. The shank of many tools with handles is made of low alloy steel, and the working part is made of high speed steel welded to each other.
The basic properties that the tool material should have
1. High hardness
The hardness of the tool material must be higher than the hardness of the workpiece material to be machined, which is the basic feature that the tool material should have.
2. Sufficient strength and toughness
The material of the cutting part of the tool must withstand great cutting force and impact force when cutting. The bending strength and impact toughness reflect the ability of tool material to resist brittle fracture and edge breakage.
3. High wear resistance and heat resistance
The wear resistance of tool materials refers to the ability to resist wear. The higher the hardness of the tool material, the better the wear resistance; The higher the high temperature hardness, the better the heat resistance, the tool material at high temperature resistance to plastic deformation, anti-wear ability is also stronger.
4. Good thermal conductivity
Large thermal conductivity means good thermal conductivity, and the heat capacity generated during cutting is easily transmitted out, thereby reducing the temperature of the cutting part and reducing tool wear.
5. Good technology and economy
In order to facilitate manufacturing, the tool material is required to have good machinability, including forging, welding, cutting, heat treatment, grindability and so on. Economy is one of the important indexes to evaluate and promote the application of new tool materials.
6. Resistance to bonding
Prevent the workpiece and the tool material molecules under the action of high temperature and high pressure adsorption bond.
7. Chemical stability
It means that the tool material is not easy to react chemically with the surrounding medium at high temperature.
Tool coating
Aluminum alloy indexable inserts are now coated with hard or composite layers of titanium carbide, titanium nitride, alumina by chemical vapor deposition. The physical vapor deposition method that is being developed can be used not only for aluminum alloy tools, but also for high-speed steel tools such as drills, hobs, taps and milling cutters. As a barrier that prevents chemical diffusion and heat conduction, the hard coating slows down the wear rate of the tool during cutting, and the life of the coated blade is about 1 to 3 times higher than that of the uncoated blade.
How to choose a tool
Tool selection is carried out in the human-machine interaction state of NC programming. The tool and handle should be correctly selected according to the machining capacity of the machine tool, the performance of the workpiece material, the processing procedure, the cutting amount and other relevant factors.
The general principle of tool selection: easy installation and adjustment, good rigidity, high durability and accuracy. On the premise of meeting the processing requirements, try to choose a shorter tool handle to improve the rigidity of the tool processing. When selecting the tool, the size of the tool should be adapted to the surface size of the workpiece to be machined.
1. End milling cutter is often used to process the peripheral outline of plane parts.
2. When milling the plane, carbide blade milling cutter should be selected.
3. When processing convex and grooves, choose high-speed steel end milling cutter.
4. When processing the blank surface or roughing the hole, you can choose the corn milling cutter with cemented carbide blade.
5. For the processing of some vertical surface and variable bevel contour, ball end milling cutter, ring milling cutter, conical milling cutter and disk milling cutter are often used.
6. In the processing of free-form surface, because the cutting speed of the end of the ball head tool is zero, so in order to ensure the processing accuracy, the cutting line spacing is generally very dense, so the ball head is often used in the finishing of the surface.
7, flat head tool in the surface processing quality and cutting efficiency are better than the ball head knife, therefore, as long as the premise of ensuring but cutting, whether it is rough surface machining or finishing, should be preferred to choose flat head knife.
8. In the machining center, various tools are installed on the tool library, and the tool selection and tool change are carried out at any time according to the procedure.

CNC machining tool concept
A tool is a tool used for cutting in mechanical manufacturing. Generalized cutting tools include both cutting tools and abrasive tools. The vast majority of knives are used for machines, but there are also hand tools. Since the tools used in mechanical manufacturing are basically used to cut metal materials, the term "tool" is generally understood as a metal cutting tool. The cutting tools used for cutting wood are called woodworking tools.
CNC machining tool
Tool classification
Cutting tools can be divided into five categories according to the form of the workpiece machined surface.
Cutting tools for processing various outer surfaces, including cutting tools for processing various outer surfaces, including turning tools, planing knives, milling cutters, outer surface broach and file, etc.
Hole processing tools, including drill, reaming drill, boring cutter, milling cutter and internal surface broach, etc.
Thread processing tools, including tap, die, automatic opening thread cutting head, thread turning tool and thread milling cutter.
Gear processing tools, including hob, gear shaper cutter, shaving cutter, bevel gear processing tool, etc.
Cutting tools, including inserted circular saw blade, band saw, bow saw, cutting tool and saw blade milling cutter, etc.
In addition, there are combination tools.
Hole cutting tool
Tool structure
The structure of various tools is composed of a clamping part and a working part. The clamping part and working part of the overall structure of the tool are done on the tool body; The working part of the tool (the tooth or blade) is mounted on the tool body.
The clamping part of the tool has two kinds of holes and handles. The tool with hole relies on the inner hole set on the spindle or mandrel of the machine tool, and transmits the torsional torque with the help of the axial key or the end key, such as the cylindrical milling cutter and the sleeve face milling cutter.
The tool with the handle is usually rectangular handle, cylindrical handle and conical handle three kinds. Turning tools, planing tools, etc. are generally rectangular handles; The conical handle withstands the axial thrust with the taper and transmits the torque with the help of friction. Cylindrical shank is generally suitable for smaller twist drill, end mill and other tools, cutting with the help of the friction generated when clamping torque transfer. The shank of many tools with handles is made of low alloy steel, and the working part is made of high speed steel welded to each other.
The basic properties that the tool material should have
1. High hardness
The hardness of the tool material must be higher than the hardness of the workpiece material to be machined, which is the basic feature that the tool material should have.
2. Sufficient strength and toughness
The material of the cutting part of the tool must withstand great cutting force and impact force when cutting. The bending strength and impact toughness reflect the ability of tool material to resist brittle fracture and edge breakage.
3. High wear resistance and heat resistance
The wear resistance of tool materials refers to the ability to resist wear. The higher the hardness of the tool material, the better the wear resistance; The higher the high temperature hardness, the better the heat resistance, the tool material at high temperature resistance to plastic deformation, anti-wear ability is also stronger.
4. Good thermal conductivity
Large thermal conductivity means good thermal conductivity, and the heat capacity generated during cutting is easily transmitted out, thereby reducing the temperature of the cutting part and reducing tool wear.
5. Good technology and economy
In order to facilitate manufacturing, the tool material is required to have good machinability, including forging, welding, cutting, heat treatment, grindability and so on. Economy is one of the important indexes to evaluate and promote the application of new tool materials.
6. Resistance to bonding
Prevent the workpiece and the tool material molecules under the action of high temperature and high pressure adsorption bond.
7. Chemical stability
It means that the tool material is not easy to react chemically with the surrounding medium at high temperature.
Tool coating
Aluminum alloy indexable inserts are now coated with hard or composite layers of titanium carbide, titanium nitride, alumina by chemical vapor deposition. The physical vapor deposition method that is being developed can be used not only for aluminum alloy tools, but also for high-speed steel tools such as drills, hobs, taps and milling cutters. As a barrier that prevents chemical diffusion and heat conduction, the hard coating slows down the wear rate of the tool during cutting, and the life of the coated blade is about 1 to 3 times higher than that of the uncoated blade.
How to choose a tool
Tool selection is carried out in the human-machine interaction state of NC programming. The tool and handle should be correctly selected according to the machining capacity of the machine tool, the performance of the workpiece material, the processing procedure, the cutting amount and other relevant factors.
The general principle of tool selection: easy installation and adjustment, good rigidity, high durability and accuracy. On the premise of meeting the processing requirements, try to choose a shorter tool handle to improve the rigidity of the tool processing.
