The vise may be clamped to the table at any point in itslength. Work held in its jaws can be presented at any angle whateverin regard to the axis of the emery wheel head, by making suitableadjustment of the swivel vise, the table and the long slide.

The round belt should be as loose as possible. General the cutter to the tooth rest by all cases when it is possible, limit the movement of the GRINDING. 253 long slide by the stops furnished for the purpose, for the follow-ing reasons: It prevents the wheel from striking the head stock or cutterin concave grinding. It prevents the wheel from running too deep into formedcutters and side milling cutters when grinding radial teeth. It prevents the cutter from passing off the tooth rest, besidesbeing convenient in quite a number of other instances occurringin the use of the grinder. It is convenient and sometimes necessary in grinding cuttersfor clearance on the right-hand end of the emery wheel spindle,to swing the knee on the column to the right at an angle of from5 to 15. This applies especially in angle cutters and smalicylindrical cutters, when the belt is liable to strike the cutter orcen
