The BM 400/400-R lapping machine is designed specifically for profiled hard-metal inserts, as it has a fixed mechanical aluminium chuck onto which our special high power open-field magnetic chuck is affixed. This special magnetic chuck has a magnetic force 10 times stronger than that of a conventional magnetic chuck and therefore holds firmly the hard-metal inserts to be lapped.

The BM 400-R lapping machine features a switch for shortening the carriage run and an external tank with pump supplied as standard.

MVM offers a full range of accessories, thereby making the BM 400/400-R a complete lapping machine solution.
