What are the advantages of ultra-high speed cutting process compared with conventional cutting process?

Often the cutting speed than the conventional cutting speed of several times to dozens of times higher than the cutting is called high-speed cutting, it is mainly used in the finishing process, in the high-speed cutting state with the increase in cutting speed, the cutting force decreases the surface quality of the machining to improve, most of the heat of the cutting by the chips and cutting oil away, the workpiece basically stays cold, but the tool life with the improvement of the cutting speed has been reduced. Compared with conventional cutting, high-speed cutting has the following advantages:

(1) high processing efficiency. With the substantial increase in cutting speed, the feed rate is also a corresponding increase of 5 to 10 times. Metal removal rate can reach 3 to 10 times the conventional cutting. At the same time, the machine tool rapid air travel speed increases significantly, also reduces the non-cutting air travel time, greatly improving the productivity of the machine tool.

(2) cutting force reduction. After the cutting speed reaches a certain value, the cutting force can be reduced by more than 30%, especially the radial cutting force is greatly reduced, especially conducive to the precision machining of thin-walled fine ribs and other parts with poor rigidity.

(3) workpiece thermal deformation is reduced. High-speed cutting tool thermal hardness, 95% ~ 98% of the cutting heat by the chip and cutting oil speed away, the workpiece can basically keep the cold state.

(4) the processed surface quality is high. High-speed cutting, the vibration frequency of the machine tool is particularly high, it is far away from the "machine tool - tool - workpiece" process system of the intrinsic frequency range, the work of smooth vibration is small.

(5) is conducive to ensuring the size of the parts, shape and position accuracy. High-speed cutting due to the fast molding speed, can ignore the conventional cutting by man, environment, equipment, etc. on the process of the impact, thus greatly improving the accuracy of the workpiece.

(6) processing costs are greatly reduced. High-speed machining to improve processing efficiency and processing quality, reducing the grinding and finishing processes. At the same time, tool wear and cutting oil usage have different programs to reduce, from the comprehensive situation can significantly reduce the cost of enterprise production.

With the continuous development of the metal processing industry, ultra-high-speed cutting process is also becoming more mature, and the supporting tools, equipment, workpiece materials, cutting oil and other products are also in the innovation and replacement, through the improvement of supporting equipment and raw materials performance can significantly improve the core competitiveness of enterprises.
