Collets advantages
1, The rubber elastic collet's construction is of durable synthetic rubber compound permanently bonded to hardened steel jaws, it is unaffacted by heat, coolants and cutting chips and retains its flexibility over a long service life as compared to spring metal collets designs.
2, With a spring-type collet, unless the bore is exactly sized to the workpiece diameter there will be reduced contact, resulting in compromised accuracy and grip force.
3, With a rubber elastic collet, the segments always remain parallel to the workpiece,helping to maintain optimum accuracy and grip force.
4, Each collet segment is joined to the adjacent segments with vulcanized rubber.This ensures that the collet segments always remain parallel to the workpiece as the collet is compressed, and the gripping force is 3 times than the common spring split steel collet.
5, The one-piece construction ensures its flexibility and resists deterioration from heat, coolants and cutting chips.
6, All segments is cut from one piece collets, it has higher hardness and durability, so the gripping force and accuracy can't be matched by the spring split steel collets.
7, The rubber elastic collets can seal the workpiece and the machine spindle, so it can protect the workpiece from grinding material and cutting chips damage.

The rubber elastic collets steel hardness is HRC58-62, it is processed by cryogenic treatment.it can improve the collet's stability, the runout is less than 0.01mm, and the clamping range tolerance nominal diameter is +/- 0.5mm.
