5. This tool holder accepts all ER32 collets
6. Run out: ≤0.00008"
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, Surface hardness: 58±2 HRC.
◎ Shank is longer, suitable for deep hole 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.
