The cutting effect factors of machining center

Views: 12     Author: Site Editor     Publish Time: 2017-05-09      Origin: Site

The machining center is a kind of mechanical and electrical products, After workpiece clamping, the CNC system can control the machine tool according to different processes of automatic selection, automatic tool setting, automatically change the spindle speed, feed rate, continuous completion of drilling, boring, milling, reaming, tapping and other processes, thus greatly reducing the clamping time and measuring tools and adjust auxiliary process time, also has good economic effect of processing more complex shapes, high precision, varieties of frequent replacement parts.

There are many factors that influence the cutting speed, and the machining center can be summarized as follows:

A. Tool material. The cutting tool material is different and the maximum cutting speed is also different. High speed steel with high temperature cutting speed is less than 50m / min, high temperature resistant tungsten carbide tool above cutting speed could up to 100M / min, the high temperature ceramic tool cutting speed can be as high as 1000 / min.

B. Workpiece material. The hardness of the workpiece material will affect the cutting speed of the tool, the cutting speed of the cutting tool with the same cutting tool needs to be reduced, and the cutting speed can be increased when the soft material is processed.

C. Tool life. In case the tool use time (life) requirements are long, it will use a lower cutting speed. On the contrary, the higher cutting speed can be used.

D. Cutting depth and feed. In case the cutting depth and feed is large, cutting heat will increase, CNC machine tool cutting speed should be reduced.

E. Shape of cutter. The shape of the cutting tool, the size of the angle and the sharpness of the cutting edge will influence the selection of cutting speed.

F. Use of cutting fluid. Cutting fluid is used in cutting, which can effectively reduce the cutting heat and improve the cutting speed.

G. Machine performance. In case the rigidity of the machine tool is high, the precision is also high, and the cutting speed can be improved.
