Description
Nickel coating NMTB30-ER32-2.76" Collet Chuck CNC Machine Tool Holder
CNC milling collet chuck arbor NMTB-ER, DIN2080 collet clamping tool holder of various sizes, high speed and
high precision machining. Mechanical spindle and cutting tools and other accessories. High precision NMTB
shank tool holder. For the market for automatic tool change device.
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.. 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 1/2" - 13 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.
ChongDe is a manufacture in R&D, production, sales and services with ISO9001 certificate. The main products
are precision tool holder, clamping collet, pull stud, nut, spanner and other machine tool accessories with the
standards of ISO, DIN, ANSI/ASME, JIS and local GB, etc.
Products advantages
1. The unique design of nut: high speed cutting, reduce drag and cutting noise and improve work efficiency,
Balance for G2.5 30000rpm, G6.3 12000rpm.
2. General purpose high speed, high precision machining, cutting effect is good.
3. Surface "environment protection", special coating surface treatment, improve the hardness and endurance
of the surface, cleaness better, accuracy stable.
4. Higher system accuracy.
5. Higher system stiffness.
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.
