How To Improve the CNC Machining Surface Quality
Regarding to discuss the CNC Machining Surface Quality of the parts during the manufacturing process, which mainly depends on the surface layer geometry and microscopic appearance errors and the physical mechanical properties. In general actual machining process, strengthen the relevant technological process, use of related technology and improve the machining details of the part, and by ensuring that parts surface roughness to prevent parts using performance is affected by the surface roughness. Therefore, adopting the correct machining process which is very helpful to improve the CNC machining surface quanlity of parts
How to select the better manufacturing technique for cnc machining parts?
-
Reasonable design cut in-out the route
When we have used CNC machine to machining parts, the cutting line should be designed to optimize the cutting angle of machine tool. In order to reduce the effect of cutting marks and ensure the surface quality is not affected, the cutting tool needs to be planned.
The cutting point of the tool mainly starts from the peripheral extension of the part, so as to ensure smooth contour surface. And the cutting tool should choose the smaller feed speed as far as possible, so it can be cut at a slow speed to make the cutting smooth transition, thus to ensure the final cutting quality.

Select the machining method correctly
In general, there are two ways of milling and reverse milling( down cutting and up cutting) when working with cnc milling machine. The milling machining effect is better than the reverse milling. Therefore, we usually choose the milling to improve the surface quality of the parts when machining. In the turning of the shaft parts, we also need to choose the same lathe tool as possible for different non-coaxial neck processing, so as to reduce the marks cause by the grafting.
-
Use a new type of efficient tool
The efficiency and performance of cnc machine are inseparable with cutting tools. For the machining of parts with higher precision, we should not only pay attention to the perfect technological process, but also choose and use the new high efficient tool. Today’s optimization design can use the new concept of tools, can be more reasonable to solve the security of the machining, precision, surface roughness, high speed cutting and optimize the ability of cutting path.
-
Adopt the best cnc machining program.
Optimize the cnc machining program, provide the best numerical control data for processing, which can improve the CNC machining surface quality better. Compared with ordinary machining tools, cnc machine tools need not only the operator has high operating level, but also high level in programming and process analysis. At the same time, in order to ensure machining accuracy, we also need to streamline program to improve production efficiency.
