Front-mounted hollow collet chuck, internal-mounted cylinder, need not to match power cylinder.
The clamping precision is 0.05~0,08mm, away from the chuck end 10mm.
Applicable to CNC lathe, ordinary lathe and other automatic equipment,can realize the processing of automatic feeding and clamping.
Aluminum alloy cylinder body, light weight, good heat dissipation.

Note
Please add a shield when rotate at high speed to avoid objects shot hurting people.
This chuck’s waterproof ability is insufficient, please don’t use cutting fluid.
Have a probability of stuck. When used for automatic feeding device, there is the trouble of disruption.
The above data are the standard parameters, personalized customized solutions can be provided according to customer's requirement.
