ER11M 5/8" Collet Chuck Tool Holders With Straight Shank 2"

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.

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%.

1. For deep hole machining

2. Shank is 5/8" diameter, 2" length

3. All critical tool holder surfaces precision ground

4. Material: 20CrMnTi / JIS-SCM415

4. Made from alloy steel hardened to HRC56-60

5. This tool holder accepts all ER11 collets

6. Coolant through capability

7. Run out: ≤0.00008" 

TYPE A / TYPE M / TYPE UM ARE DIFFENT, WHICH CAN BE JUDGED BY THEIR APPEARANCE

◎ Material: 20 CrMnTi / 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.

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.
