KORLOY TECH-NEWS - English Stainless steel Turning insert ҁ High toughness PVD coating insert optimized for cutting Hard-to-cut material small and medium sized valve and fitting Stable cutting due to applying Edge - TechTM for increasing chipping resistance and welding resistance

Stainless steel Turning insert Stainless steel is a kind of metal materials used for various industries such as food, medical appliance, automobile components and construction due to its excellent corrosion resistance, high hardness and gloss. Especially it is widely used for valve, fitting and pipe components which require corrosion resistance. Because these components are usually produced under the casting process, they have uneven surface and complicated shape. For that reason, impact in unstable approach of cutting and welding characteristic of Stainless steel leads to chipping and fracture...

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...
