A brief overview of matters needing attention in CNC lathe processing

In CNC lathe processing, what matters should the operator pay attention to in order to better perform CNC lathe processing. Although it is similar to ordinary lathe processing, because the CNC lathe is a one-time clamping and continuous automatic processing to complete all turning processes, there are some differences that require us to pay special attention. The precautions for CNC lathe processing are as follows: 1. Choose a reasonable cutting amount. An economical and effective processing method must be a reasonable choice of cutting conditions. The cutting speed, feed rate and depth of cut will directly cause tool damage. If the cutting speed is increased, The temperature of the tool tip will rise, and mechanical, chemical, and thermal wear will occur. Generally, if the cutting speed is increased by 20%, the tool life will be reduced by 1/2. The user should choose the appropriate cutting speed according to the processed material, hardness, cutting state, material type, feed amount and depth of cut, etc. Regular and stable wear is the ideal condition. 2. Reasonable selection of tools (1) When roughing, choose tools with high strength and good durability to meet the requirements of roughing. (2) When finishing turning, choose high-precision and durable tools to meet the requirements of machining accuracy. (3) In order to reduce the tool change time and facilitate tool setting, machine clamped knives and machine clamped blades should be used as much as possible. 3. Reasonable selection of fixtures (1) Try to use general fixtures to clamp the workpiece, and do not use special fixtures. (2) The positioning datums of the parts should be coincident, so as to reduce the positioning error. 4. Determine the processing route (1) It should be capable of processing precision and surface roughness requirements. (2) Shorten the processing route as much as possible, thereby reducing the idle travel time of the tool. The above is the entire content of the article, which is explained here for reference only!
