Four Methods to Improve The Surface Quality of CNC Machined Parts

1. Adopting better CNC machining programs

Optimizing the CNC machining program to provide better CNC data for machining can improve quality. Compared with ordinary machine tools, CNC machining not only requires operators to have a high level of operation skills in the machining of parts, but also a high level of programming and process analysis. To ensure machining accuracy, it is necessary to optimize and streamline the program in order to improve production efficiency.

2. Using new and efficient cutting tools

The efficiency and performance of CNC machining are closely related to the cutting tools. For parts with high precision requirements, it is not only necessary to pay attention to a complete process flow, but also to select and use new and efficient cutting tools. The current tool optimization design can apply new tool concepts to more reasonably solve problems such as safety, accuracy, surface roughness, high-speed cutting, and the ability to optimize cutting paths in mechanical machining.

3. Choosing the correct cutting method

When using a CNC milling machine for machining, there are two methods: forward milling and reverse milling. The precision machining effect of forward milling is better than that of reverse milling. Therefore, in the processing of parts, if conditions permit, it is advisable to choose sequential milling to improve the surface quality of the parts. In the turning of shaft parts, it is also necessary to choose the same turning tool as much as possible for the machining of different shaft necks, so as to better reduce the marks caused by tool contact.

4. Reasonably design the entry and exit routes

When using CNC machining for part processing, it is necessary to design the cutting in and cutting out routes and optimize the cutting angle of the machine tool. In order to achieve the effect of reducing cutting marks and ensuring that the surface quality is not affected, it is necessary to plan the cutting of the tool. The entry point of the cutting tool mainly starts from the peripheral extension of the part, ensuring a smooth contour surface. The cutting tool should choose a smaller feed rate as much as possible to maintain a slow cutting speed, making the cutting smooth transition and ensuring cutting quality.

We can make various precision components such as heat dissipation precision parts, communication chambers, mobile phone precision parts, household appliance precision parts, furniture hardware precision parts, safety monitoring equipment, underwater camera precision parts, pneumatic/hydraulic valve bodies CNC machined parts, etc .
