Grinding method of hard alloy taper shank end mill
What is taper shank end mills?
Taper shank end mills, also known as Morse taper shank end mills, range in size from 6 mm to 100 mm. It consists of blade and Morse taper shank. The cutter is used to rough machining plane, step, groove and vertical plane. The number of teeth is small and the space of chip holding is large, which is suitable for rough machining.
High productivity milling cutter continuous rotation, and allows a higher milling speed, so it has higher productivity.
In intermittent cutting milling, every cutter tooth is cutting intermittently, especially in end milling, the milling force fluctuates greatly, so the vibration is inevitable. When the vibration frequency is the same as or multiple to the natural frequency of the machine tool, the vibration is the most serious. In addition, when high-speed milling, the cutter teeth have to undergo periodic cold and thermal shock, which is prone to crack and chipping so that the tool life is reduced.
Multi-Tool and multi-edge cutting milling cutter has many teeth and the total length of the cutting edge is large, which is beneficial to improve the tool life and productivity. But there are also two problems as follows: first, the cutter teeth are prone to radial runout, which will cause unequal load and uneven wear of cutter teeth and affect the quality of a machined surface; Second, the chip space of the cutter teeth must be enough, otherwise the cutter teeth will be damaged.
Different milling methods, according to different processing conditions, in order to improve tool life and productivity, different milling methods can be selected, such as reverse milling, forward milling, symmetric milling and asymmetric milling.
