The mechanical processing program is one of the technical documents that stipulate the mechanical processing process and operation method of the parts. Under the specific production conditions, the more reasonable process and operation method are written into the technical documents according to the prescribed forms. Used to guide production.
1. Remove the jaws of the vise in the machining of the mechanical parts, and machine the two M4 threaded holes. Two steel plates 2 with the jaws and 1.5 mm thick are riveted with aluminum countersunk rivets and 0.8 mm thick. The hard brass plate 3 is fastened to the jaws with M4 countersunk screws 1 to form a durable soft jaw. This also protects the part from being pinched and interchangeable.
2.in the mechanical machining with a magnet to absorb small parts (fees) suction and take is not convenient. 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 mechanical processing, 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, so that the adsorption force can be prevented to prevent slipping, and the waste will be rewarded by the boss.
4. In the machining process, when the 1 hex wrench is short and can not be stressed, the tube with the inner diameter slightly larger than the wrench can be inserted into the slot from the section of the slot, which can be regarded as a long handle.
In addition, in machining, there are many workpieces that are not produced by one-time production. When the workpiece is produced, it is just a rough model. If the factory becomes a real product, Among them, some mechanical equipment must be used for machining, and machining according to different product requirements, in order to become a valuable product.
In order to ensure the efficiency of machining and the quality of the products produced, the four principles must be followed when machining.
- the benchmark first:When machining a product using mechanical equipment, a datum must be determined so that there is a positioning reference for subsequent processing. After the datum is determined, the datum is then machined.
- Divide the processing stage:When the product is machined, it needs different degrees of processing according to different product requirements. The degree of processing needs to be divided. If the accuracy is not high, then a simple roughing stage is required. The progress requirements of the products are becoming more and more strict, and the semi-finishing and finishing stages are followed.
- the first face and the back hole:When machining, for workpieces such as brackets, it requires both plane machining and mechanical hole machining. In order to process the holes, the accuracy error is smaller.
- finishing processing:This processing principle is roughly the processing of some polishing and polishing, which is usually the step after the product has completely completed the architecture.
