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%.
TYPE A / TYPE M / TYPE UM ARE DIFFENT, WHICH CAN BE JUDGED BY THEIR APPEARANCE
◎
Material: 20CrMnTi / JIS-SCM415, Surfac
e hardness: 58±2 HRC.
◎
Shank is longer, suitable for deep h
ole processing.
◎
Outer diameter and other parts after grinding, eliminate
the
unbalanced allowance, conducive to the
stability of the cutting
◎
Can reduce to the selection of lengthen cutting tool,
reduce
cost and improve efficiency
◎
Run out ≤0.00008

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.
