Usually in the industry, the machining process specification is one of the technical documents that stipulate the machining process and operation method of the parts. It is to write the more reasonable process and operation method according to the specified form under the specific production conditions. Process documents are used to guide production after approval. With the innovation of technology, We gave you some tips on the few common techniques used in CNC machining. 1. Remove the jaws of the vise in machining, and machine two M4 threaded holes. Two steel plates 2 that are 1.5 mm thick with the jaws are riveted with aluminum countersunk rivets and 0.8 mm thick. The brass plate 3 is fastened to the jaws with the M4 countersunk screw 1 to form a durable soft jaw. This also protects the part from being pinched and interchangeable. 2. It is inconvenient to suck and take small parts (fees) with magnets during machining. An iron plate 2 can be sucked under the magnet 1, not only can suck a lot of small pieces, but also pull the small pieces of the iron plate into the collecting box immediately. Not enough to be impressed but very practical. 3. When the pulley is driven in the machining process, the pulley often slips between the pulley and the axle. On the axle, a series of nests are drawn with a boring bit of 15~18mm. This can form an adsorption force to prevent slipping, and the waste will be rewarded by the boss. 4. In the machining process, when the hex wrench 1 is short and can not be stressed, the pipe with the inner diameter slightly larger than the wrench can be inserted into the groove from the section of the milling groove, and can be regarded as a long handle. In cnc machining, there are many workpieces that are not produced by one-off production, but when the workpiece is produced, it is just a rough model. If the factory becomes a real product, It is necessary to use some mechanical equipment for machining and machining according to different product requirements, so that it can become a valuable product.
