Usually in the industry, the machining process specification is one of the process documents that specifies the machining process and operating methods of parts. It is a process document that, under specific production conditions, writes reasonable process and operating methods in the prescribed form, which is approved and used to guide production. With technological innovation, experienced machining manufacturers have summarized the following common tips for everyone:
1、 In mechanical processing, remove the jaws of the vice and machine two M4 threaded holes. Align two 1.5mm thick steel plates 2 with the jaws, and use aluminum countersunk rivets to rivet on a 0.8mm thick hard brass plate 3. Secure it to the jaws with M4 countersunk screws 1, forming a durable soft jaws. This can also protect the parts from being pinched and has interchangeability.
2、 It is not convenient to use a magnet to suck small parts (expensive parts) in mechanical processing. You can suck an iron plate 2 under magnet 1, which not only can suck many small pieces, but also pulling the iron plate apart will automatically tilt the small pieces into the collection box. Not enough to impress, but very practical.
3、 During the transmission of the belt pulley in mechanical processing, the belt pulley often slips between the wheel shaft. Use a ¥ 15-18mm drill bit to scratch a series of grooves on the wheel shaft, which can form adsorption force to prevent slipping. The boss will reward you for turning waste into treasure.
4、 In mechanical processing, when the handle of the hex wrench is short and cannot exert force, a pipe with an inner diameter slightly larger than the wrench can be milled into a groove and the wrench inserted into the groove, which can be used as a long handle.
In addition, in mechanical processing, many workpieces are not produced in one go, but when they are produced, they are just a rough model. If they become real products after leaving the factory, some mechanical equipment needs to be used for mechanical processing according to different product requirements, in order to ultimately become a product with practical value.
In order to ensure the efficiency of mechanical processing and the quality of the products produced, four principles must be followed during mechanical processing.
1. Benchmark First:
When using mechanical equipment to process products, it is necessary to determine a reference plane so that there can be a positioning reference in subsequent processing. After determining the reference plane, the reference plane must be processed first.
2. Divide processing stages:
When machining products, different degrees of processing are required according to different product requirements, and the degree of processing needs to be divided. If the accuracy requirement is not high, then a simple rough machining stage is sufficient. The progress requirements of the product are becoming increasingly strict, and the subsequent stages of semi precision processing and precision processing will need to be carried out.
3. Face first, hole later:
When machining, for workpieces such as brackets, they require both flat machining and mechanical hole machining. In order to reduce the accuracy error of the processed holes, machining the flat surface first and then the holes is beneficial to reduce the error.
4. Smooth processing:
This processing principle roughly refers to some polishing and polishing processes, which are usually carried out after the entire product structure is completed.
