Brief introduction to the processing skills of CNC lathe

CNC lathe is a high-precision, high-efficiency automatic machine tool. Using CNC lathe can improve processing efficiency and create more value. The emergence of CNC lathes has freed the enterprise from the backward processing technology, CNC lathe processing technology and ordinary lathe. The processing technology is similar, but since the CNC lathe is a single clamping, continuous automatic machining completes all turning operations, so the following aspects should be noted.

Reasonable choice of cutting amount

For high-efficiency metal cutting, the material to be processed, the cutting tool, and the cutting conditions are the three major factors. These determine machining time, tool life and machining quality. A cost-effective processing method must be a reasonable choice of cutting conditions.

The three elements of the cutting conditions: cutting speed, feed rate and depth of cut directly cause damage to the tool. As the cutting speed increases, the tip temperature rises, causing mechanical, chemical, and thermal wear. Cutting speed is increased by 20% and tool life is reduced by 1/2.

The feed condition is related to the wear behind the tool in a very small range. However, the feed rate is large, the cutting temperature rises, and the rear wear is large. It has less effect on the tool than the cutting speed. Although the depth of cut has no effect on the cutting speed and the feed rate, in the case of small depth cutting, the hardened layer is produced by the material to be cut, which also affects the life of the tool.

The user should select the cutting speed to be used according to the material to be processed, hardness, cutting state, material type, feed amount, depth of cut, and the like.

The selection of the most suitable processing conditions is selected on the basis of these factors. Regular, stable wear and longevity are ideal conditions.

However, in actual operations, the choice of tool life is related to tool wear, machined dimensional changes, surface quality, cutting noise, and heat processing. When determining the processing conditions, it is necessary to conduct research according to the actual situation. For difficult-to-machine materials such as stainless steel and heat-resistant alloys, a coolant or a rigid blade can be used.
