Mechanical parts processing industry is the pillar of the national economy, with a very promising future. In the processing of precision mechanical parts, processing plant will have many requirements and regulations on the processing process to ensure the qualification rate of the factory parts. So we know what are the tricks of precision machining? Let's take a look below!
Precision machining tricks
Trick one: the vise jaws removed, another two M4 threaded holes, the two flush with the jaws of the 1.5mm thick steel plate 2, with aluminum countersunk rivets riveted on the 0.8mm thick hard brass plate 3 will be fastened to the jaws with M4 countersunk screws 1, forming a durable soft jaws. This also protects the hardware parts from being clamped badly, but also has interchangeability.
Tip 2: For tightening the workpiece there is first positioning and then clamping, but for a workpiece it, the first clamping and then positioning, because the clamping will certainly try the workpiece deformation, so, should first clamping and then positioning, for 6-point positioning, looking to limit its degrees of freedom.
Trick 3: When the hexagonal wrench 1 shank is short and can not be force, the tube with an inner diameter slightly larger than the wrench can be inserted into the slot from a section of the milling groove, which can be used as a long shank.
Tip 4: When the pulley drive, the pulley often slips between the pulley and the axle, and a series of nests are scratched on the axle with ￠15~18mm scratching nest drill, which can form an adsorption force to prevent slippage and turn waste into treasure, and the boss will reward.
Trick five: the use of magnets to absorb small parts (fee pieces) suck and take are not convenient, you can suck an iron plate 2 under the magnet 1, not only can suck a lot of small pieces, and the iron plate will be pulled away, small pieces will immediately and automatically dumped into the collection box, not enough to impress the heart, but very practical.
