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.

The importance of product processing technology
The process of the internal structure of the product is closely related to the processing cost. The processing technology used by the product directly determines the production cost, and the processing efficiency and production capacity will also be affected by it.
From the perspective of product design, if the manufacturing threshold of processing technology can be fundamentally reduced, on this basis, certain processing costs can be reduced, and the processing CT time of CNC machine tools can be shortened, and the processing quality and processing quality can be improved. Efficiency can be improved. Can greatly improve the CNC machining capacity.

Tool life management control in CNC machining
The life management control of the tool by the CNC system is to calculate the number of tool machining, or to determine the processing time. Therefore, when the tool life reaches the expected number of machining times or time of the system, the CNC automatically stops the action. It is assumed that when manual supervision is not in place, or when the tool is not able to stop changing in the expected situation, the CNC machining process will be affected. Therefore, tool life is a key factor affecting CNC production capacity.
Especially when the CNC machining process of a workpiece is too much, the processing amount is cumbersome, and the dimensional accuracy of the processing is relatively strict, the tools to be used will be more. At this time, the CNC tool library automatically changes the tool, and the knife action is more frequent, and the tool wear is larger, so that the manual tool change and machine adjustment are more frequent.
Therefore, tool wear is an important indicator that affects the normal production rhythm and capacity of CNC. Through technical measures to improve the process, improve the overall life of the tool, not only can save the cost of the tool, but more importantly, can reduce the stopping time of the CNC spindle, so as to improve the efficiency of CNC processing, improve the production quality and capacity.

CNC milling is often used to machine POM parts. Tools with sharp edges help to get the best Angle, as well as surface finish. Therefore, it is reasonable to use a single slot milling cutter to process Delrin. These cutters prevent chip buildup during machining operations.
2.POM CNC drilling
Standard twist and center drills are best suited for processing polyformaldehyde resins. These materials have strong, sharpened edges that ultimately allow for smooth milling operations on Delrin. The optimal cutting speed of the drilled POM must be approximately 1500rpm and the lip torsion Angle 118°.
3.POM CNC turning
POM CNC turning operation is similar to brass turning operation. The best results can be achieved by maintaining high speed turning at the same rate as the medium feed rate. In order to prevent interference and excessive chip accumulation problems, a chip-breaker must be used for precision turning operations.
4. Blanking and punching
Blanking and stamping, both methods are preferred for small and medium-sized complex parts. During operation, cracks in the sheet can lead to major problems of improper processing. To eliminate this problem, it is best to preheat the Delrin plate and use a manual or high punch.
Highlights: "During POM CNC machining, it is important to keep the POM tight or hold the POM and use a hard steel or carbide tool.
List of Delrin grades for CNC machining
The two most common acetal grades are very useful for CNC machining; Polyformaldehyde resin 150, polyformaldehyde resin; 100 (AF). Let's evaluate their compatibility;
1. Delrin 150
Derlin 150 belongs to the acetal homopolymer family. It has high mechanical strength, stiffness and wear resistance. Thanks to these unique features, it is ideal for CNC machining of gears, bushings, gaskets and automotive interior and exterior finishes. In addition, its stability under high temperature conditions makes it ideal for irrigation and conveyor parts.
2. Delrin 100(A)
Delrin 100 A is integrated with polytetrafluoroethylene (PTFE) for enhanced mechanical stability and viscosity. It is widely used in gear systems or components that require low friction characteristics. In addition, it has strong moisture and chemical resistance. In addition, it eliminates the self-lubricating (oil or grease) characteristic, making it different from other Delrin grades.
Surface treatment options for POM
The desired surface finish plays a key role in the machining process. When it comes to surface treatment, two options are usually employed: machining and sandblasting. Here is a brief introduction to these;
After processing
CNC machining often leaves a bumpy surface or texture on the surface of the acetal part. When rough or textured parts are needed to improve the frictional properties of the parts, the surface treatment is preferred. The typical roughness range that can be achieved by machining is about 32 to 250 microinches (0.8 to 6.3 microns).
Pearl burst
In most cases, machining tools leave marks on acetal parts. Sandblasting is often used to prevent tool marks and enhance the visual effect of Delrin machined parts. It works by releasing glass beads or fine particles onto the surface of machined parts under high pressure. In addition, it improves durability and provides a valuable, smooth, matte, aesthetically pleasing and satin-polished appearance to polyformaldehyde resin machine parts.
There are other techniques; For example; Anodizing, polishing, painting and stamping. However, most design engineers prefer the above two options due to economic feasibility.
What are the limitations of Delrin CNC machining?
However, there are huge benefits to using Delrin for CNC machining. Besides, it also has some disadvantages. Here are Delrin's limitations;
Adhesion: Although acetal has excellent chemical resistance, it often presents challenges in bonding with strong adhesives. To overcome this problem, designers may need to employ post-treated surface options for best results.
Thermal sensitivity: Thermal sensitivity is a noteworthy issue for design manufacturers. The ability of acetone alcohols to withstand high temperature conditions is very significant. However, it is well suited for applications where mechanical stability is critical. But in some cases, when it is exposed to high temperature conditions, there will be deformation or distortion problems. Compared with nylon, nylon shows higher strength and structural strength even in harsh environments.
High flammability: The processing of polyformaldehyde resin faces the challenge of flammability. It is sensitive to temperatures above 121 degrees Celsius. It is recommended to always use a coolant, such as air coolant, to maintain the temperature during the processing operation. In order to overcome or control flammability problems, it is also necessary to use A Class A fire extinguisher when processing POM.
