Hi,
Started new job with a lathe , 86 Hitachi seiki with fanuc 10t. It was running good suddenly it stopped between a auto feed block and the now the collet would not open. in spite of restart, the collet does not work. when I try a spindle run at 650rpm in MDI, the spindle rotates at about 5-6. The proximity switch on the spindle end is working when I switch between external clamp and internal clamp. Any help is thanked in advance.
Sri
