The Need to Know Is Basic

Selection of carbide milling cutter
In addition to end milling cutters CCGT Insert and some end milling cutters and cemented carbide as milling cutter materials, other types of milling cutters generally use high speed steel, especially tungsten, molybdenum series and high vanadium high speed steel, which has good effect, and its tool durability is 1 to 2 times higher than that of W18Cr4V. The grades of cemented carbide suitable for making stainless steel milling cutters include YG8, YW2, 813, 798, YS2T, YS30, etc.
The adhesion and fusibility of stainless steel are strong, and the chips are easy to adhere to the cutting edge of the milling cutter, which worsens the cutting conditions; During up-milling, the blade slides on the hardened surface first, which increases the tendency of work-hardening; During milling, the impact and vibration are large, which makes the milling cutter edge easy to collapse and DNMG Insert wear.
The corrugated edge end milling cutter is used to process stainless steel pipes or thin-walled parts. The cutting is light and fast, the vibration is small, the chips are fragile, and the workpiece is not easy to deform. High speed milling with carbide end milling cutter and indexable end milling cutter can achieve good results in milling stainless steel.
When milling stainless steel, the forward milling method should be used as far as possible. The asymmetric forward milling method can ensure that the cutting edge can be cut off from the metal smoothly, the chip bonding contact area is small, and it is easy to be thrown off under the action of high-speed centrifugal force, so as to prevent the chip from peeling off and collapsing on the front face of the tool when the cutter tooth re-enters the workpiece, and improve the durability of the tool.
