There are many types of machining centers, and there are many factors that affect the cutting speed, but they are generally consistent. In summary, there are the following aspects.
1. Tool material. Different cutting tool materials allow different maximum cutting speeds. The high-temperature steel cutting speed of high-speed steel tools is less than 50m / min, the high-temperature cutting speed of tungsten carbide tools can reach more than 100m / min, and the high-temperature cutting speed of ceramic tools can be up to 1000 / min.
2. Workpiece material. The hardness of the workpiece material will affect the cutting speed of the tool. When the same tool is used to process hard materials, the cutting speed needs to be reduced, while the softer materials can be processed. c. Tool life. Long tool life (life) requirements, you should use a lower cutting rate. Conversely, a higher cutting speed can be used.
3. Cutting depth and feed amount. Cutting depth and feed volume are large, cutting resistance is also large, cutting heat will increase, so the cutting speed of CNC machine tools should be reduced.
4. The shape of the tool. The shape of the tool, the size of the angle, and the sharpness of the cutting edge all affect the choice of cutting speed.
5. Use of cutting fluid. Using cutting fluid during cutting can effectively reduce the cutting heat and thus increase the cutting speed.
6. Machine performance. The machine has good rigidity and high precision to increase the cutting speed. Otherwise, the cutting speed needs to be reduced.
