This is a vice giving three rotations around different axes to get any plane orientation, the main purpose of which being to machine carbide tip holders and milling cutters. Such vices do exist, but are expensive (see figs 1 and 2 and photo 1): In fig. 1 a 'dummy' machine table and ' machine vice are drawn to show clearly the angles R1, R2, R3 and the machining directions. This sketch will also be used later to determine the required machining angles with the help of 3D CAD. We need three rotations, but have already one R1 around the vertical axis from our standard vice 1. The two others are given in the following way: a cylinder (part 2) is tightened in the vice jaws across its plane ends, the cylinder leaning on the machine vice moving jaw shears (like on a Vee), giving the second rotation R2 around the cylinder axis. The third rotation R3 is given to part 3 around the spigot axis, this spigot being then locked in part 2 by a cotter 4 and screw 5, and also optionally by screw 8.
