High Accuracy ,ER Straight Shank Collet Chuck
chongde ER16M 3/4" Collet Chuck Tool Holders With Straight Shank 1.65"
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 C 8, C 10, C 12, C 16...
Etc.. Mold industry, and high-speed engraving machine, used more.ER/M straight
Shank is longer, suitable for deep hole processing.
Comprehensive inspection way of chuck:
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: 20 CrMnTi / JIS-SCM 415, 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.
