Do You Know the Precautions for CNC Lathe Machining?

To choose the cutting amount reasonably. In metal cutting, the processed material, cutting tool and cutting conditions are three important factors.
1. Lathe processing time, tool life and processing quality are all decisive factors. The choice of cutting conditions must be based on cost-effective processing methods. The three elements of cutting conditions: cutting speed, feed and cutting depth. As the cutting speed increases, the temperature of the tool tip increases, which will cause mechanical, chemical and thermal wear. The cutting speed is increased by 20%, and the tool life can be reduced by 1/2.

2. The effect of cutting depth on the tool is not as large as the cutting speed and feed rate, but in the micro-cutting process, the material being cut will produce a hardened layer, which will also affect the life of the tool. The user should choose the cutting speed to be used according to the material being processed, hardness, cutting state, material type, feed amount, and cutting depth. According to these factors, it is more appropriate to choose better processing conditions. Normal and stable wear to reach life is an ideal state.

3. However, in actual operation, the choice of tool life is related to factors such as tool wear, changes in the processed dimensions, cutting surface quality, cutting noise and cutting heat. When deciding the processing conditions, the actual situation should be studied. For difficult-to-process materials such as stainless steel and heat-resistant alloys, coolant or materials with higher hardness can be used.

Choose cutting tools reasonably.
1. When rough turning, tools with high strength and good durability should be used to meet the requirements of large back knife and large feed when rough turning.

2. When finishing machining, choose high-precision and durable tools to ensure the required machining accuracy.

3. In order to reduce the tool change time and facilitate tool setting, the machine card knife and machine card knife should be used as much as possible.
