3), work in-process in the heart, select the speed of mainshaft be 1500 revs/min, with special fixture folder just before cabinet shell, milling: plane A, plane B, plane C, boring: blind hole A, screwed hole B bottom outlet, each dimensioned is to drawing requirement, with slide gauge, depth indicator, go-no go gauge inspection;
4), work in-process in the heart, select the speed of mainshaft be 1500 revs/min, with special fixture folder just before cabinet shell, milling: end face A, auger shell pit E bottom outlet, tapping thread mill drilling E, each dimensioned is to drawing requirement, with screw gauge, three Coordinates;
5), work in-process in the heart, select the speed of mainshaft be 1500 revs/min, with special fixture folder just before cabinet shell, milling: end face B, auger shell pit C and screwed hole D bottom outlet, tapping thread mill drilling C and screwed hole D, each dimensioned is to drawing requirement, with screw gauge, three Coordinates;
6), on tapping machine, tapping thread mill drilling A, screwed hole B, each dimensioned, to drawing requirement, is checked with screw gauge;
7), by product drawing inspection warehouse-in.
The present invention is easy to process, improves product quality and production efficiency, reduces production cost.
