Now processing D8 long 300 aluminum rod, with instrument car processing, sleeve will pinch aluminum rod, is there any good way or suggestion? At present we do with bakelite collet, but life is not enough. Please master suggestions, thank you!
Thank you for your reply, now we also generally know the direction, is the choice of soft material collet, remove the sharp edges,
All the corners of the chuck (slit, end face) fall about 0.5 of the fillet
the problem is that the material is most suitable? Copper will leave traces on the surface, and after a long processing time, the nylon will soften and become invalid. The elastic collet is probably not very realistic, because it is the instrument lathe, structure is simple, a thousand dollars.
