Description
C ER/M straight tool holders for mechanical spindle and cutting tool and other accessory tool connection.
Is a simple, popular spindle shank connection standard, mainly C8, C10, C12, C16... Etc.. Mold industry, and high-speed engraving machine, used more. ER/M straight shank is longer, suitable for deep hole processing.
Surface of the clamping inner hole is grinding by high speed inner-aperture grinder, and inspect by standard pneumatic measurement instrument; the big end contact area rate is above 90%.

Cryogenic Treatment
◆ -384.8℉ long cryogenic, nearly all of the residual austenite into martensite.
◆ Carbide precipitation of Nanoscale particles, increasing the hardness and toughness.
◆ Reducing residual stresses.
◆ Wear resistance significantly improved.
Thermal Aging Processing
◆ long stereotyped thermal limitation removal of grinding residual stress.
Extension for Machining Deep Hole
◆ Solve the difficulty in machining deep hole.
