The box-type parts are the main basic parts, generally used as the carrier of other parts, by which some shafts, bushings, gears, end covers, fasteners, etc. are assembled to maintain the correct mutual positional relationship, and It’s a important components. As you can say, a device with independent functions usually has box parts. Therefore, the processing quality of the box parts has a direct impact on the accuracy, performance and life of the equipment.

Structural features of the box parts

stainless steel Check valve

There are many types of cabinet parts, and their sizes. The structural form varies greatly depending on its use, but there are still some common features in the structure:

1. The shape of the box structure is generally complicated, thin and uniform, and the interior is cavity type.

2. There are many high-precision bearing support holes and flats on the wall of the box that need to be machined, and many low-precision fastening holes need to be machined.

3. The box parts are generally large in volume and quality, especially the box parts used by metallurgical enterprises, many of which belong to large welded structural parts or castings.

;The processing technical requirements for box parts are:

1) Plane accuracy and surface roughness requirements

2) Dimensional accuracy of the support hole, geometric accuracy and surface roughness

3) Pitch accuracy and parallelism between adjacent holes with gear meshing relationship, coaxiality between coaxial holes

4) Parallelism and surface roughness of the assembly base and the machining positioning base

5) The dimensional accuracy of each supporting hole axis and each plane to the mounting base surface, mutual positional accuracy, etc.
