PURPOSE:To make a sharp improvement in productivity and mechanical availability factor and betterment in quality stabilization attainable, by making a smooth installing method of a jig to a spindle part inside a rotary abrasive machine, a one-touch setting method of a lot of works and abrasive operation on a large number of works within the same abrasive time all performable. CONSTITUTION:A rotary abrasive jig installs a keyway in a spindle inside an abrasive machine, a spindle is inserted in a keyway guide for plural jigs where a work is locked and, after a spindle cover is installed, a jig lockup ring is slidden in a lower part of the spindle, then these plural jigs are locked. Each screw of the same pitch is installed in an inner surface of a collet chuck inside these plural jigs and a work locking rod 8, having tensile force resistable to centrifugal force at the time of rotational polishing, and plural forms are installed in a tip of a work lockup collar 2, whereby all design forms are made polishable. In addition, each rubber packing is installed in a receiving jig 6, a cover jig 7 and a sliding part, preventing an abrasive material from penetrat ing into the jig inside, and a lot of works are made possible to be set up and vice versa with one-touch operation. |
