Machining process procedures is one of the process documents that specify the mechanical machining process and operation methods of parts, it is in the specific production conditions, the more reasonable process and operation methods, written in accordance with the prescribed form into process documents, after approval used to guide production. So we know what tips in the process of machining mechanical parts? Let me share it with you today!
First mechanical parts processing in the vise jaws removed, another two M4 threaded holes, two flush with the jaws of 1.5mm thick steel plate 2, with aluminum countersunk rivets riveted on 0.8mm thick hard brass plate 3 will be fastened to the jaws with M4 countersunk screws 1, forming a durable soft jaws. This can also protect the parts are clamped bad, but also has interchangeability.
Second, mechanical parts processing with a magnet to absorb small parts (fee parts) suck and take are not convenient. Can suck an iron plate 2 under the magnet 1, not only can suck a lot of small parts, and the iron plate will be pulled away from the small parts will immediately and automatically dumped into the collection box. Not enough to impress the heart but very practical
Third, mechanical parts processing in the pulley drive when the pulley often slipped between the pulley and the axle, in the axle with ￠ 15 ~ 18mm scratch nest drill bit to scratch a series of nest, so that adsorption can be formed to prevent slippage, turning waste into treasure.
Fourth, in the machining of mechanical parts, when the hexagonal wrench 1 handle is short and can not be force, the tube with an inner diameter slightly larger than the wrench can be milled from a section of the slot, the wrench will be inserted into the slot, which can be used as a long handle.
In mechanical parts processing, there will be a number of workpieces are not produced through a one-time production, but when the workpiece is produced, it is only a rough model, if the factory into a real product, which will have to be mechanically processed with the help of some mechanical equipment, according to the different product needs for mechanical processing, and finally to become a product with use value
In order to ensure the efficiency of mechanical processing, and the production of qualified product quality, in the time of mechanical processing, must follow the four principles.
1, the benchmark first.
In the use of machinery and equipment for product processing, a datum must be determined, so that in the subsequent processing to have a positioning reference, to determine the datum, then the datum must first be processed.
2、Division of processing stages.
Products in mechanical processing, according to the different product requirements to carry out different degrees of processing, the degree of processing needs to be divided, if the requirements for precision is not high, then a simple roughing stage on the line. The progress of the product requirements are becoming more and more stringent, the subsequent semi-finishing and finishing stages will be carried out.
3、Face first and then hole.
In the time of machining, for such a workpiece as the bracket, it is necessary to both plane processing and mechanical hole processing, in order to process the hole accuracy error is smaller, first processing plane after processing hole is conducive to reducing the error.
4、Light finishing processing.
This processing principle is roughly the processing of some grinding and polishing, it is usually in the product all finished architecture after the step.
