Claims

[Claims for Utility Model Registration] (1) The corners of one steel rectangular parallelepiped or cube are made of several different lengths a, b, c,
A master block 1 which is precisely cut at right angles so as to form a plurality of cutting surfaces A, B, C, D... having widths a', b', c', d'... and a workpiece 5.
Cutting surface A selected according to the thickness, height, width, etc. of
A presser plate 8 is provided to clamp the workpiece 5 at the right angle portion formed by B, C, D..., and the presser plate 8 is held in contact with a predetermined outer surface of the master block 1, and is screwed onto the presser plate 8. A precision vise characterized in that a workpiece 5 is pressed and fixed by a workpiece holding bolt 9. (2) The precision vise according to claim (1) of the utility model registration, characterized in that relief grooves 4 are cut at the right-angled intersections formed by the cutting surfaces A, B, C, and D. (3) Contact piece 1 with a flat front and a hemispherical rear
