The length of the life of the milling cutter is the most concerned issue for every customer, but this is a very general issue, because many factors may affect the service life of the tool, such as processing materials, processing methods, and processing experience.
So how to improve the service life of tungsten steel milling cutter?
(1) Reasonable selection of cutting amount. The cutting amount affects the durability of the tungsten steel milling cutter. If the cutting depth and feed rate are too large, the cutting force increases, and the wear of the tungsten steel milling cutter will also accelerate. Therefore, our choice of reasonable cutting amount can also prolong the service life of the tungsten steel milling cutter.
(2) Improve the geometric angle of the tungsten steel milling cutter. The angle of the tungsten steel milling cutter and the shape of the blade affect the change of the cutting force. For example, when the front angle increases, the chip deformation is small, the cutting is light, and the cutting force and cutting heat are reduced. On the premise of ensuring the sufficient strength of the tungsten steel milling cutter, the rake angle should be taken as large as possible. When the main declination angle is reduced, the length of the cutting edge participating in cutting increases, so that the cutting heat is relatively dispersed, and the cutting edge angle increases, which can make cutting Temperature drop.
(3) Grasp and adjust the optimum cutting conditions, set good cutting conditions and maintain them. Understand the cutting state of accessories through vibration analysis, etc., and make adjustments in time, so that the tungsten steel milling cutter has a good working environment. Once the tungsten steel milling cutter is replaced, the size must be adjusted to ensure proper fastener conditions and cutting conditions.
(4) Reasonable selection of milling cutter material. The workpiece material and processing conditions have a great influence on the cutting performance of tungsten steel milling cutters. To process different materials, it is necessary to know how to choose different tools in order to meet the requirements of cutting.
