Generally speaking, when manufacturers re-produce milling cutters, there are certain requirements for the texture, hardness and material of milling cutters, so that the quality of milling cutters provided to customers can meet the needs of customers, so what materials are high-hardness end mills suitable for processing?
The answer is stainless steel. Stainless steel is widely used, but machining stainless steel has become a major challenge for technicians due to its different properties from other general materials.
1. In the process of stainless steel processing, except for end mills and some end mills and cemented carbide as milling cutter materials, all other types of milling cutters are high-speed steels used, especially tungsten-molybdenum and high-vanadium high-speed steels. is a good effect.
2. Stainless steel has strong adhesion and fusion, and chips are easy to adhere to the cutting edge of the milling cutter, which deteriorates the cutting conditions; during up milling, the cutting edge first slides on the hardened surface, which increases the tendency of work hardening; during milling The impact and vibration are large, which makes the edge of the milling cutter easy to chip and wear.
3. When milling stainless steel, the cutting edge must be sharp and can withstand impact, and the chip groove should be large. Large helix angle cutters can be used to machine stainless steel tubes or thin-walled parts with wavy end mills. The cutting is light, the vibration is small, the chips are brittle, and the workpiece is not deformed. High-speed milling with carbide end mills and indexable end mills in stainless steel can achieve good results. When milling stainless steel, climb milling should be used as much as possible. Asymmetric climb milling can ensure that the chip bonding area is small, and it is thrown off by centrifugal force, preventing the chip from hitting the rake face when the cutter teeth re-cut into the workpiece. Stripping and cutting improve tool durability.
