[CNC lathe processing technology skills]Reasonable choice of cutting parameters

CNC Lathe Machine Manufacturer China shares that CNC numerical control lathe is a kind of high precision, high efficiency of machine tool automation, using a CNC lathe can improve machining efficiency and create more value, the appearance of the numerical control lathe enterprises to get rid of the backward processing technology, numerical control lathe machining process is similar to the processing technology of the engine lathe, but as a result of the numerical control lathe is a clamping, automatic processing to complete all turning process, which should be paid attention to:

Reasonable selection of cutting parameters

For high efficiency metal cutting, the material to be machined, cutting tools and cutting conditions are the three major factors. These determine the processing time, tool life and processing quality. The economical and effective processing method must be the reasonable choice of cutting conditions.

Cutting conditions of the three elements: cutting speed, feed and cutting depth directly cause damage to the tool. Along with the increase of cutting speed, the temperature of the tool tip will rise, which will produce mechanical, chemical and thermal wear. A 20% increase in cutting speed will reduce tool life by half.

The relationship between feed conditions and tool back wear occurs on a very small scale. But large feed, cutting temperature rise, wear behind. It has less effect on the tool than cutting speed. Cutting depth on the impact of cutting tool although not cutting speed and feed, but in the small deep cutting, cutting material produced by the hardening layer, will also affect the life of the tool.

The user shall select the cutting speed of the Heavy Duty CNC Lathe Machine to be used according to the material to be machined, hardness, cutting state, type of material, feed, cutting depth, etc.

The most suitable processing conditions are selected on the basis of these factors. Regular, steady wear is the ideal condition for reaching the life span.

However, in practice, the choice of tool life is related to tool wear, machining size change, surface quality, cutting noise, machining heat, etc. In determining the processing conditions, it is necessary to study according to the actual situation. For refractory materials such as stainless steel and heat resistant alloys, use coolant or use a rigid blade.
