What are the requirements of Er spring collet for fixture workpiece specification?

November 18, 2020

In the design scheme of Er spring chuck, there are various types of workpieces, such as metal stamping parts, aluminum profiles and components. Therefore, in the design scheme, it is necessary to estimate the allowable range of standard tolerance of workpiece clamping position. The application of spring collet can greatly improve the processing efficiency, and can keep all the machining surfaces of the parts to be processed once clamping. Then according to the matching of round bar machine and cutting equipment, the whole process of automatic left and right material can be maintained, and finally intelligent manufacturing and continuous processing can be maintained. In such an application, the non drilling time saved for a single workpiece will be very small, but in the whole processing process, the product of reasonable arrangement of time for each workpiece and the number of processed workpieces will add up to a huge amount of time saved.

So what are the specifications of Er spring collet for fixture?

1. It is especially suitable for small diameter workpiece processing.
2. The clamping time of workpiece is very short, which can keep the material around quickly.
3. The replacement time is very short, which can maintain the rapid replacement of different specifications of tooling fixtures.
4. Relative to the chuck, the clamping precision is higher, and the coaxiality is maintained stronger during the turning process.
5. Er has lower cost and higher coordination ability than chuck for special-shaped and boring spring collets.
6. The spring chuck can produce the least cutting speed arm on the CNC lathe with the insert type spindle bearing in Er, so it has more machining room space and processing stiffness than chuck.
7. Er spring chuck is enveloping type clamping, which can maintain the surface layer of workpiece more effectively and produce a large drilling torque.
