In the process of processing non-standard precision mechanical parts in large mechanical processing plants, although there are many very inconspicuous tips, if you can know and master these tips, you will be more efficient, get twice the effect, and get twice the result with half the effort! Below we introduce a few commonly used techniques in the processing of non-standard precision mechanical parts, let everyone know:
Non-standard precision machinery parts processing
Remove the vise to clamp the jaws and machine two M4 threaded holes, align two 1.5 mm thick steel plates flush with the jaws, riveted a 0.8 mm thick hard brass plate with aluminum rivets, and fix them with M4 countersunk screws On the jaws, a durable soft jaw is formed. This can protect precision mechanical parts from being pinched.
It is inconvenient to use magnets to attract small precision mechanical parts. An iron plate can be sucked under the magnet. It can not only absorb many small precision mechanical parts, but also can pull the iron plate apart. Small precision mechanical parts will automatically fall into the collection box, which is very practical.
If the pulley slips between the pulley and the axle while driving, a 15~18mm pit drill can be used to mark a series of pits on the axle to form adsorption force and prevent slipping.
Generally, the workpiece is positioned first and then clamped, but for some workpieces, the clamping will cause the workpiece to deform. Therefore, for such a workpiece, it must be clamped and then positioned, find 6 positioning points, and find the degree of freedom that limits it.
Large mechanical processing plants attach great importance to the quality and efficiency of non-standard precision mechanical parts processing. If they do not use a lot of manpower and financial resources, they can also improve production efficiency more effectively.
