KORLOY TECH-NEWS - English Universal insert for Steel and Cast iron cutting ҁ ҁ Increased chipping resistance and stable tool life in Steel and Cast iron cutting Applying universal substrate with high adhesion and coating layer with good wear resistance and chipping resistance

Universal insert for Steel and Cast iron cutting In recent cutting industries, the demand on high speed machining for productivity improvement is steadily increasing because there are various shapes in workpieces and cutting time is reducing due to less machining allowance from the heat/cold forging technology development. Therefore, universal grade with wear resistance and chipping resistance is necessary for cutting various workpiece in high speed. KORLOY launches CVD universal grade for Steel and Cast iron cutting for higher productivity according to those changes in market. NC5320, with the...

KORLOY TECH - NEWS 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...
