Description

     Guide bush is a component for guide device, and matched with corresponding guide pin. The fit clearance between guide bush and guide pin is very small, within the range of 0.05mm. It's generally used on moulds or some machine, to keep the accuracy of motion.
     The guide bushing is essentially a circular flange, usually between 10mm and 40mm outside diameter, which fixes to the router base and acts rather like a small ring fence. The cutter plunges through the middle of the bush and the outside edge of the ring runs against the jig or template, to position the cut.
     After guide bush and guide pin assembled, the device has below functions:
a) accurately locate core and cavity side of plastic injection mould, and make them match perfectly and move smoothly;
b) support weight of the mould;
c) protect core or cavity inserts
