Product Description

CNC Machine Tool Holder NMTB40-ER40-70L Collet Chuck

High precision NMTB shank tool holder, balance G2.5 30000rpm and G6.3 12000rpm for choseDIN2080 collet clamping tool holder of various sizes, high speed and high precision machining. Mechanical spindle and cutting tools and Other Accessories Higher system accuracy and Higher system stiffness.

NMTB Tool Holders for mechanical spindle and cutting tool and other accessory tool connection.The unique design of nut: high speed cutting, reduce drag and cutting noise and improve work efficiency, Is a simple, popular spindle shank connection standard, mainly NMTB30 NMTB40 NMTB50 Etc.. Mold industry, and high-speed engraving machine, used more.

1. Material: 20CrMnTi

2. Run out of the inside shank cone ≤0.0001" 

3. Constructed of alloy steel hardened to 56 – 60 HRC for long, durable service life

4. Rear thread for Pull Stud is 5/8" - 11 UNC

5. Taper precision ≤ AT3 and part of the standard size are tested by Diebold standard inspection tools which made in Germany.

6. Surface: Nickel coating and polishing nickel coating.


Anti-rust, Anti-corrosion, Durability better
◆ Coating adhesion strong, enhance hardness, and anti-rust better in different surroundings, such as acid, alkali, ammonia, salt etc.
◆ Overall nickel coating, including inside and outside cone, even if you do not take any anti-rust actions, it will not rust either,
don't influence processing precision and spindle.
◆ Improve cleanness, precision more stable, surface more smooth, feel more comfortable and appearance nicer.

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.
