KORLOY TECH-NEWS - English Heptagonal face mill with 14 double-sided corners ҁ ҁ Minimized chattering of workpiece due to maximum lead angle and sharp cutting edge Reduced cutting resistance and improved chip emissions by high helix angle application

Heptagonal face mill with 14 double-sided corners In the various industries including automotive components business, workpieces are manufactured with casting for easy-producing complicated shapes and lowering cost. However, due to the characteristic of casting manufacturing, facing is necessary on each uneven facing surface for assembling. In casting machining, complicated shapes of workpiece and uneven surface creates low clamping force, chattering, unstable tool life, bad surface finish and even shortening life of equipment. KORLOY launches the double-sided face mill, RM14 to solve those troubles...

For the safe metalcutting Use safety supplies such as protective gloves to prevent possible injury while touching the edge of tools. Use safety glasess 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...
