Precision machinery parts processing plays a crucial role in various industries, including aerospace, automotive, medical, and manufacturing.Precision machinery parts have specific requirements to ensure optimal performance.One crucial aspect is the material used for processing. If the hardness of the material being processed surpasses that of the lathe tool, it can potentially cause irreparable damage.Therefore, it is essential to select materials that are compatible with precision machining.

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.

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. This breakthrough has not only improved the machining accuracy of stainless steel components but has also significantly enhanced the efficiency of the process. As a result, manufacturers can now rely on CNC machining to achieve precise and efficient production of stainless steel precision parts.

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.

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.

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.

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.

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. Therefore, the standard tool handle must be used in order to make the standard tool for drilling, boring, expanding, milling and other processes quickly and accurately installed on the machine spindle or tool library. The number of tools should be reduced as far as possible; After a tool is installed, it should complete all the processing parts that it can carry out; Rough finishing tools should be used separately, even if the same size specifications of the tool; Milling before drilling; Surface finishing is carried out first, and then 2D contour finishing is carried out. Where possible, the automatic tool change function of CNC machine tools should be used as much as possible to improve production efficiency.

Problems encountered in processing aluminum and solutions when processing pure aluminum, easy to stick knife analysis and solutions:

1. Aluminum material is soft in texture and easy to stick at high temperature;

2. Aluminum is not resistant to high temperature, easy to open;

3. Related to processing cutting fluid: good oil lubrication performance; Good water-soluble cooling performance; High dry cutting cost;

4. When processing pure aluminum, the end mill dedicated to aluminum processing should be selected: positive front Angle, sharp cutting edge, large chip discharge slot, 45 degrees or 55 degrees helix Angle;

5. The material of the workpiece and the CNC tool has a greater affinity.

6. Rough front tool processing soft materials.

Recommendation: Machine tool conditions are poor to good requirements are low to high, please use high-speed steel, coated polished carbide, PCD polycrystalline diamond and single crystal diamond.

7. Low speed can be avoided by cutting fluid, high speed oil mist lubrication, the effect can be improved, aluminum alloy suitable

Due to the high temperature, high pressure, high speed, and the parts working in the corrosive fluid medium, the application of difficult to process more and more materials, the automation level of cutting processing and the processing accuracy requirements are getting higher and higher. In order to adapt to this situation, the development direction of the tool will be the development and application of new tool materials; Further develop the vapor deposition coating technology of the tool, and deposit higher hardness coating on the matrix of high toughness and high strength, so as to better solve the contradiction between hardness and strength of the tool material; Further development of indexable tool structure; Improve the manufacturing accuracy of the tool, reduce the difference in product quality, and optimize the use of the tool.How to choose CNC aluminum alloy machining tool.
