Here is CNC Metal Prototype manufacturer talking about Dry cutting requirements for tool materials.
If you have any idea about CNC Stainless Steel Prototype, welcome to contact us and discuss.
The dry-cut tool material must have excellent thermo-hardness and wear resistance to effectively withstand the high temperature of the cutting process; a lower coefficient of friction to reduce the friction between the tool and the chip and the workpiece surface to suppress the cutting temperature. Rise higher strength and impact resistance to withstand greater cutting forces and worse cutting conditions. To achieve dry cutting, tool materials with high heat resistance (thermoset) and wear resistance are especially necessary.
Current cubic boron nitride (CBN), polycrystalline cubic boron nitride (PCBN), diamond, polycrystalline diamond (PCD), ceramic (A12O3, Si3N4), cermet (CERAMIC), ultrafine-grained carbide and hard Tool materials such as alloy coatings have been widely used in dry cutting. In the past two years, Iskar has developed a number of tool materials for dry cutting: IB90 and IB85. The CBN content is as high as 85% and 90%.
The wear resistance and toughness of the insert are high, which can cope with the vibration caused by interrupted cutting. Recommended for high-speed cutting of cast iron and interrupted cutting and roughing of hardened steel. The grades with low CBN content, IB55, IB50, CBN content of 50% and 55%, are more suitable for semi-finishing and finishing. IB10H is an ultra-fine grained CBN with higher wear resistance and toughness for high-speed continuous cutting and high surface quality; IB20H fine grain and medium grain CBN for continuous-slight intermittent cutting; Also, IB10HC, IB25HC, and IB25HA are coated with TiN, Ti(C, N, O) and Ti(C, N) for various corresponding applications.
