KORLOY TECH-NEWS - English PVD insert for cast iron Milling ҁ ҁ PVD Ion plus-TechTM provides long tool life and stability The optimal substrate for cast iron cutting with coating adherence technology ensures regular tool life

PVD insert for cast iron Milling In cast iron machining, the formation of short, broken chips results in a lower load on the rake face of the insert, leading to slower wear progression. However, the relief surface, which comes into direct contact with the workpiece, experiences longer friction time and therefore wears out relatively quickly. Especially, nodular graphite cast iron, compared to gray cast iron, has high hardness and high toughness characteristics. During machining, it forms built-up edges and adhesion on the surface of the insert, causing uneven chipping. Additionally, to remove...

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...
