CNC machining general exponential word control precision machining, including CNC milling machine, CNC lathe, CNC boring and milling machine, etc. In the production of cemented carbide, nc machining is often required.

CNC turning feed line refers to the path through which the tool moves from the beginning of the tool point to return to the point and finishes the processing program, including the cutting path and the tool cutting, cutting and other non-cutting empty stroke path.

When machining CNC lathes, the following principles should be followed in general.

1, should be able to ensure the accuracy and surface roughness of the processed workpiece.

2. Minimize the processing path, reduce the idle stroke, improve the processing power.

3. Simplify the workload of numerical accounting and processing procedures.

4. For certain repetitive procedures, subroutines should be used.

strengths

CNC processing has advantages:

1. The number of tooling is greatly reduced. After changing the shape and size of parts, only the parts processing procedures are revised to adapt to the development and modification of new products.

2, stable processing quality, high processing accuracy, high repetition accuracy, suitable for aircraft processing needs.

3. The production power of multiple varieties and small batch production is higher, which can reduce the time of preparation, machine tool adjustment and process view, and can shorten the cutting time due to the use of cutting amount.

4. Messy surfaces that are difficult to be processed by conventional methods can even be processed with some parts that cannot be observed.
