Of the part that has positional precision demand each concern the surface is in workpiece same be finished in second installation and assure, be like an axis kind the verticality of the circle outside the spare parts and end panel, the coaxial of each aperture on the between each aperture parallelism in casing aperture department, verticality, same axes is spent etc. Installation law places implementation with clamping apparatus outfit commonly. Clamping apparatus is workpiece of clip of outfit of in order to (and guide cutting tool) device. The fixed position component on clamping apparatus and clamping unit can make workpiece wins correct seat quickly, make its are secured go up in clamping apparatus and machine tool. Accordingly, work location is convenient, tall and fixed position precision is stable, the efficiency that hold clip is tall also. When with essence of life when standard fixed position, the fixed position precision of workpiece can be amounted to commonly 0. 0l ㎜. So, with special fixture the workpiece that hold clip is used extensively at medium, large quantities of mixing mass-produced. But, because make special fixture charge taller, cycle is longer, be in so odd when pre production, use special fixture rarely, use general clamping apparatus however. When the treatment precision demand when workpiece is higher, can use the built up fixture that standard unit assembles, the component after using is detachable time. CNC Milling
