What is the basic knowledge of doing a machining

At this stage, there are many machining platforms, such as: 168, Haizhi**, Made-in-China.com, Gasgoo Automobile Network, Soga, etc., but several platforms have their own focus: 168 and Made-in-China.com's orders are not limited to industries, and the order volume is very large, and you need to be careful to screen out the orders that suit you.

Gasgoo is only focused on the automotive industry. SOGA has its own processing plant and also supplies orders. Haizhi ** is specialized in non-standard parts, both domestic and foreign procurement.

If you look at the machining order alone, the quantity and quality of Haizhi's purchase order are relatively good, and the drawings above have been reviewed, so the possibility of false orders is relatively small, and there are more foreign customers, and they are also very friendly to foreign trade customersGood luck with your business.

Drawing recognition, sharpening of tools, operation of machine tools, processing methods of various workpieces, measurement of workpieces. These are the most basic.

From the analysis of the part drawing to the program inspection, the whole process of processing the sample. There are two ways to program CNC machine tools, "tool point" refers to the starting point of the tool's relative workpiece movement during CNC machining, and it is also the starting point of program operation, also known as "program origin".

The part program is a machining program written on the input medium, or it can be an input prepared for the computer, and the processing program is obtained after processing.

The process of manufacturing and processing a workpiece or part, using the method of machining, directly changing the shape, size and surface quality of the blank, etc., to make it a part is called machining process. For example, the processing process of an ordinary part is rough machining - finishing - assembly - inspection - packaging, which is a general process of processing.

Machining refers to the process of changing the dimensions or properties of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure machining.

The machinery required for processing consists of digital milling machine, digital molding grinder, digital display lathe, EDM machine, universal grinder, machining center, laser welding, medium wire, fast wire, slow wire, cylindrical grinder, internal grinder, precision lathe, etc., which can be used for precision parts turning, milling, planing, grinding and other processing, such machinery is good at turning, milling, planing, grinding and other processing of precision parts, and can process various irregular shape parts, with a machining accuracy of up to 2 m.

Machining is an abbreviation for machining, which refers to the processing process of removing materials through precise machining by mechanical precision.

Finishing, or precision machining, is processing that is carried out with high-precision processing machinery. There are two main ways to achieve precision machining of parts: one is to use high-precision machining machine tools to process high-precision parts; The second is to use error compensation technology to improve the machining accuracy of parts.

There are two main categories of machining: manual machining and CNC machining. Manual machining refers to the method of processing various materials by manually operating mechanical equipment such as milling machines, lathes, drilling machines, and sawing machines by mechanical workers. Manual machining is suitable for the production of small batches of simple parts.

CNC machining (CNC) refers to the use of CNC equipment by mechanical workers to process, including machining centers, lathe centers, EDM wire cutting equipment, thread cutting machines, etc.

Cold working of metals, such as turning, pliers, milling, planing, grinding, drawing, boring, rolling, etc.

Machining refers to a process in which the shape and size of a workpiece are changed primarily through unloading and unloading. Machining is divided into various types according to different conditions. Generally, we will divide machining into cold working and hot processing according to the temperature state of the workpiece to be processed.

Cold working is the processing at room temperature without causing a chemical reaction or change in the image of the workpiece. Thermal processing, on the other hand, is processed at a temperature higher or lower than the normal temperature, causing chemical or phase changes in the workpiece.

Machining is divided into cold working and hot working.

Cold working mainly includes turning, pliers, milling, planing and grinding.

Hot working is mainly casting, forging and welding.
