Description
CAT40-ER40-4" Collet Chuck CNC Machine Tool Holder
CNC Milling Collets Chuck Arbor CAT-ER,
DIN6499 collets clamping tool holder of various sizes, high speed and high
precision machining.
Mechanical spindle and cutting tools and other
accessories. High Precision CAT shank Tool Holder, balanced G2.5 for  choose.
CAT Tool Holders for mechanical spindle and cutting tool
and other accessory tool connection.
Is a simple, popular spindle shank connection
standard, mainly CAT30 CAT40 CAT50... Etc  . . Mold
industry, and high-speed engraving
machine, used more.
1. Works on all CAT40 machines
2. Run out of the inside shank cone ≤0.0001"
3.  Rear thread for pull stud is 5/8" - 11
4.  Collet Chuck accepts all ER40 collets
5. Nickel coating surface, Anti-rust, anti-corrosion, durability better.
6. Tool Holder is Balanced to G2.5 at 20,000 rpm
7.  Constructed of alloy steel hardened to 56 – 60 HRC for long, durable service life
8.  AT3 or better accuracy standard taper specification for maximum contact with spindle.
Chong De is a manufacture in R&D,
production, sales and services with ISO9001 certificate. The main products are
precision
tool holder, clamping collets, pull
stud, nut, spanner and other machine tool accessories with the standards of
ISO, DIN,

Products advantages
1. The unique design of nut: high speed cutting, reduce
drag and cutting noise and improve work efficiency,
Balance for G2.5 20000rpm.
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, surface.
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.
