Description

Nickel coating NMTB30 End Mill Holder 3/4″ Hole Diameter 2.76″ Projection

NMTB30 SLN high precision end mill holder, apply to the holder of a DIN1835-B with a solid surface of the cutting tool,

high speed and high precision machining. Mechanical spindle and cutting tools and other accessories.

NMTB tool holders for mechanical spindle and cutting tool and other accessory tool connection.

Is a simple, popular spindle shank connection standard, mainly NMTB30 NMTB40 NMTB50… Etc..

1. TIR: ≤0.0002″
2. Material: 20CrMnTi
3. Works on all NMTB30 Machines
4. Rear thread for pull stud is 1/2″-13UNC
5. Constructed of alloy steel hardened to 56 – 60 HRC for long, durable service life
6.AT3 or better accuracy standard taper specification for maximum contact with spindle.
7.Nickel coating surface， Anti-rust,anti-corrosion,durability better.

Anti-rust,anti-corrosion,durability better.

◆Coating adhesion strong, enhance hardness, andanti-rust better in different surroundings, such as acid, alkali, ammonia, salt etc.

◆Overallnickel coating , including inside and outside cone, even if you do not take anyanti-rust actions, itwill not rust either,don’t influence processing precision and spindle. Improve cleanness, precisionmore stable, surface moresmooth, feel more comfortable and appearancenicer .

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.
