What are the elements of turning and milling processing conditions for CNC machining of precision parts?

For the cutting of high-efficiency CNC lathe cnc processing metal materials, the raw materials for processing, special tools and cutting conditions are the three major factors. This decision determines machining time, tool life and machining quality. In order to develop an economical and reasonable processing method, the cutting conditions must be selected reasonably.

Reasonable selection of cutting parameters for CNC lathes

The three elements of cutting conditions in CNC lathe machining: cutting speed, feed rate and cutting depth will immediately cause damage to the tool. As the cutting speed increases, the temperature of the sharp knife will increase, causing mechanical, organic, and thermal wear. The cutting speed is increased by 20%, and the tool life will be reduced by 1/2 for CNC turning and milling.

The relationship between the feed conditions and the wear behind the tool is caused on a small scale. However, when the feed rate is high, the cutting temperature rises and the rear part wears a lot. It does less damage to the tool than the cutting speed. The cutting depth and degree are not as harmful to the tool as the cutting speed and feed rate, but in the fine cutting depth and degree cutting, the cut raw material will form a hard bottom layer, and the machining of CNC spare parts will also endanger the service life of the tool .

The customer should select the cutting speed for application according to the processed raw material, strength, cutting situation, raw material type, feeding speed, cutting depth, etc.

The selection of suitable processing conditions is based on the basic selection of these elements, with standard and stable wear is the ideal condition to achieve service life.

As we all know, in specific work, the choice of tool life is related to tool wear, changes in processing specifications, process performance, cutting noise, and processing heat. When determining the processing conditions, it must be studied according to the specific situation. CNC machining turning and milling machining For difficult-to-machine raw materials such as stainless steel plates and heat-resistant alloys, coolant or cutting edges with good hardness can be selected.
