Brief Introduction of CNC Turning Techniques

CNC Turning lathe is a kind of automatic machine tool with high precision and high efficiency. The use of CNC Turning lathe can improve the processing efficiency and create more value. The emergence of CNC Turning lathe makes enterprises get rid of the backward processing technology. The processing technology of CNC Turning lathe is similar to that of ordinary lathe, but because CNC turning lathe is a one-time installation. Clamp, continuous automatic processing to complete all turning processes, so we should pay attention to the following aspects.

Reasonable selection of cutting parameters

For efficient metal cutting, the material to be processed, cutting tools and cutting conditions are the three main factors. These determine the processing time, tool life and quality. The economical and effective processing method is bound to be a reasonable choice of cutting conditions.

Three factors of cutting conditions: cutting speed, feed rate and cutting depth directly cause tool damage. With the increase of cutting speed, the temperature of tool tip will rise, which will cause mechanical, chemical and thermal wear. Cutting speed is increased by 20% and tool life is reduced by 1/2.

The relationship between feed condition and tool back wear is generated in a very small range. But when the feed is large, the cutting temperature rises and the back wear is large. It has less influence on cutting tool than cutting speed. Although the influence of cutting depth on cutting tool is not as great as cutting speed and feed, the hardened layer of the cutting material will also affect the life of the tool when cutting in micro-depth.

Users should choose the cutting speed according to the material, hardness, cutting state, material type, feed, cutting depth and so on.

The most suitable processing conditions are selected on the basis of these factors. The ideal condition is regular and stable wear to reach life.

However, in practice, the choice of tool life is related to tool wear, dimension change, surface quality, cutting noise, heat and so on. When determining the processing conditions, it is necessary to study them according to the actual situation. Coolant or rigid blade can be used for difficult-to-machine materials such as stainless steel and heat-resistant alloy.
