DIN6499B ER32 Precision Collet(T.I.R.0.01mm)
- Material:SUJ2
- T.I.R.0.01mm
- HRC44-48
- Product description: ER collet; Made of SUJ2; Run out:0.01mm; Vacuum carburizing heat
Product introduction
High precision high durable ER collet
#Material: SUJ2
#Hardness:HRC44-48;
#Inner hole grinding far many times,sa as to reach
Ra0.4.has a mirror effect;
#Collet groove use grinding pracess,suitable for
high speed machining;
#End and the cylindrical are grinding for many times,can
reach Ra0.4,has a mirror effect;
#Surface" environmental protection",special coating
surface treatment, improve the hardness and endurance
of the surface, cleaness better,accuracy stable,surface
mare smooth.antirusf,feel comfortable,appearance nice.
Cryogenic treatment
1.-185℃ long cryogenic,nearly all of the residual
austenite into martensite
2.Carbide precipitation of Nanoscale particles,
increasing the hardness and toughness
3.Reducing residual stresses
4.Wear resistance significantly improved
≥100h超长定型热时效去除磨加工时的残余内应力.
#Thermal aging processing
≥100h long stereotyped thermal limitation removal
of grinding esidual stress.
