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.

Sheet metal, CNC, 3D printing, is the current market for equipment shell, structural parts, the most common three processing methods.
Each has its own advantages and disadvantages, and sheet metal processing is relatively simple because of the characteristics of forming, high efficiency and low cost, and there are advantages in sample, small batch and mass production.
The common raw materials for sheet metal processing are iron, aluminum, stainless steel and other metal plates, and the main processing technology is laser cutting, bending, riveting, stamping, welding, spraying and other major processes.
Sheet metal raw materials are standard plates, mainly divided into the following three categories: iron, aluminum, stainless steel.Under the same area, iron plate is the cheapest, followed by aluminum plate, stainless steel is the most expensive.
Material introduction
Material property
1. Rust
Iron plate must rust, 201 May rust, 304 does not rust, aluminum plate does not rust.
The iron plate is definitely rusty, the general appearance of the parts are through the surface treatment process such as spraying, painting, etc., to solve such problems, but the surface treatment has increased some costs, the price may not be high, but it is particularly important in mass production.
In order to solve this problem, there is also a kind of iron plate called galvanized plate（Galvanized sheet is divided into two kinds of galvanized sheet with flowers and without flowers）, it is on the basis of the original plate, plated with zinc, or almost the same price, but to solve the problem of rust, but the galvanized layer of bumps and scratches will also rust.
In order to reduce costs, galvanized sheets are generally used in the internal structure of the equipment. Of course, it can also be used as an exterior part.
（In terms of material characteristics, stainless steel 201 is relatively much harder than 304, and 304 toughness will be greater）
2. Machinability
The two main processing processes of sheet metal: bending and welding. In terms of materials, the ductility and tensile strength of iron plates and stainless steel are relatively stable, and bending and welding can be done.
Here focuses on the aluminum this material, it has different series, common 5052, 6061, 7075.
7 series aluminum, also called aviation aluminum, the highest strength, high hardness, but the hardness is too high is not suitable for bending, a break.
6 series aluminum, strength, hardness in the medium distance, but also not suitable for bending, there is also a risk of breaking.
5 series aluminum, ductility and tensile strength are also stable, suitable for bending.
The choice of aluminum, in addition to whether it is suitable for bending, the difference is also the common surface treatment oxidation process of aluminum, and the color of different series of aluminum after oxidation will also have a little difference.
In addition, compared with iron and stainless steel, the thermal conductivity of aluminum is high, welding is difficult compared with iron and stainless steel, the general factory does not necessarily have the ability to weld aluminum parts, so the welding cost is high, which is also a large part of the reason for affecting the production cost.
Conclusion
1, iron plate is the cheapest, but easy to rust, generally with spray surface treatment process, do internal structural parts and appearance parts can be. Commonly used iron plate is mainly divided into cold rolled plate and galvanized plate two kinds, the difference is whether there is a galvanized layer, the price is similar.
2, aluminum plate material cost is good, can do anodizing, can bend only 5 series, 6 series, 7 series bending will split (there are other 1 series is not introduced), not easy to rust suitable for internal structural parts, welding costs are higher, do special-shaped parts cost will be higher.
3, stainless steel does not do surface spray treatment, can do wire drawing effect, can do structural parts, shaped parts, the only disadvantage is the high price.
Introduction to bending
Before explaining the process, let's first think about what problems are mainly solved by these processing processes in several major processing industries such as CNC, sheet metal, stamping, injection molding and now 3D printing?
Aside from the specific processing details from the overall point of view, in fact, they are solving the 3D molding problem of different raw materials.
It means that although it is a different processing process, using different raw materials, the purpose of these processing processes is the same - to make a structural part with length, width and height + other characteristics.
In order to introduce the sheet metal forming process more clearly and intuitively, as well as its efficiency and advantages, we will analyze the core process of sheet metal processing - sheet metal bending from the three angles of forming principle, bending principle and cost accounting.
In actual processing, a palm-sized 3D structural part can be formed in just ten seconds, and for slightly larger workpieces, in addition to taking and placing complex points, the molding time is only tens of seconds. Do not have to open a mold to make such a big thing, tens of seconds to form the processing technology can also have? Fast forming and low cost, which is the main advantage of sheet metal bending!
One more detail, the raw material is soft before bending, but after bending, it becomes strong! This detail is a very important concept in sheet metal structural design, sheet metal can be bent to increase strength!
For example, to make a part with a relatively large area, in order to prevent deformation, we can use this strategy to directly strengthen the thin plate by bending, which can both reduce the weight and reduce the cost of raw materials.
Summary of advantages
1, low cost of raw materials: can use very thin materials to achieve a large volume; The bending process can also be used to increase the strength of the plate to solve the deformation risk. It can also be rapidly formed from the plate to the three-dimensional part by bending (remember that a large volume can be mentioned here, referring to the advantages of the sheet class at this level).
2, the molding speed is fast, the molding cost is low, the molding speed does not depend on the size, does not need to open the mold, suitable for proofing and mass production.
Sheet metal processing principles
The bending principle is that through the extrusion of the upper and lower molds, bending workpieces of different Angle sizes can be folded, and the molds are mainly composed of the lower molds and the upper molds. In addition to a molding mold, the lower mold is generally a V-slot lower mold, and different bending molds are selected according to the thickness of the bending material.
The commonly used bending die is mainly divided into two kinds of straight knife and curved knife, the main difference between the straight knife and curved knife is to consider the bending interference avoidance problem.
In addition to some special shapes, in order to ensure accuracy and improve efficiency, some molding molds will also be prepared in advance, such as shutters (which can be processed by bending machines or by punching machines), and commonly used arc molds.
