KORLOY TECH-NEWS - English high feed, Milling grade for Steel ҁ PVD coating insert for high-hardness and high-lubricative that optimized for milling applications of Steel A highly chipping-resistant grade for minimized deviation and extended tool life under various cutting conditions

Milling inserts for Steel In general, the relief and ramped surfaces of tools get easily worn out when milling steel at high speeds. Also, chipping and tool breakage problems are frequently caused in deep milling at high feeds. Often in high-speed continuous machining, plastic deformation occurs. On the other hand, thermal cracking occurs in interrupted machining at high speeds, or in wet applications. Both lead to extremely reduced tool life. In addition, build-up edges tend to be formed when machining easily welded workpieces, which decreases tool life and lowers surface finish of workpieces....

For the safe metalcutting Use safety supplies such as protective gloves to prevent possible injury while touching the edge of tools. Use safety glasses or safety cover to hedge possible dangers. Inappropriate usage or excessive cutting condition may lead tool's breakage or even the fragment's scattering. Clamp the workpiece tightly enough to prevent its movement while its machining. Properly manage the tool change phase because the inordinately used tool can be easily broken under the excessive cutting load or severe wear, and it may threat the operator's safety. Use safety cover because chips...
