(1) the main demand to clamping apparatus

When actually numerical control milling is machined, kind do not beg very complex clamping apparatus, it is OK to ask to have orgnaization of simple fixed position, clamp only. Its design principle is as same as clamping apparatus of general milling machine also, combine the characteristic that numerical control milling machines, when does here put forward to ask basically only:

1) the consistency that installs azimuth and department of machine tool coordinate and Cheng to make up coordinate to tie way to hold a part, clamping apparatus should assure to realize directional installation on the machine tool, the coordinate dimension that still asks can harmonious spare parts locates keep certain between face and machine tool is contacted.

2) wait for treatment face to be exposed adequately to maintain workpiece what to all need finish is in in this working procedure outer, clamping apparatus should be done so that open open as far as possible, accordingly clamp orgnaization component and treatment should maintain certain safe distance between the face, cell of requirement clamp orgnaization can be small at the same time low, collision happens in order to prevent clamping apparatus and sleeve of milling machine main shaft or broach shell, cutting tool in machining a process.

3) the tigidity of clamping apparatus and stability are close friends. Do not use the design that clamp dot changes in machining a process as far as possible, clamp should change to nod in must machining a process cannot when, want special attention to because change,clamp is nodded and cannot destroy clamping apparatus or work location precision.

(2) commonly used clamping apparatus is phyletic

The clamping apparatus with commonly used treatment of numerical control milling has roughly following a few kinds:

1) all-purpose built up fixture applies to small lot to produce or the medium, small-sized workpiece when development is on numerical control milling machine undertake mill is machined.

2) it is special that special mill cuts clamping apparatus for some or the fixture that design of similar a few workpiece makes, be produced in batch commonly or otherwise is not when development but when use.
