In recent years, although CNC machining methods have become mainstream, it has become a difficult problem for manufacturers to choose high-quality machining manufacturers. So how to solve this problem? Today, the editor of HKAA will teach you how to find a reliable mechanical parts processing factory.
To find a high-quality processing factory, you can examine the following aspects;
1. Standardized operating procedures
Operating procedures are the basis for ensuring product quality. When choosing a mechanical processing factory, you must have a certain understanding of the operating procedures of the machinery factory.
Learn more about it in more detail, such as: whether the safety startup inspection before startup, startup reset, and startup preheating are completed as required; the program sheet mold number, workpiece number, reference angle orientation, XYZ three-axis number acquisition method and number acquisition surface Determine whether it is reasonable; clean and arrange the clamping before loading the workpiece on the machine, tighten the screws, and check the workpiece calibration; recheck the tool and safety inspection and processing data inspection when starting processing; clean the workpiece before dismounting the machine and other related processing operations Whether the process is standardized and whether there are clear regulations.
2. Implementation of conventional processing standards
As for processing standards, any enterprise engaged in mechanical processing should pay attention to them. Processing standards are the guarantee of accuracy after products are made. Only by meeting the standards can qualified products be manufactured.
Conventional processing standards include: whether the processing requirements for the structural assembly groove on the mold core are the same as those for the mold base; whether the processing and discharge drawings are based on the engineering parts drawing; whether the parting surface polishing knife margin is not exceeded for small molds 0.05mm/S, while large molds cannot exceed the standard of 0.08mm/S, etc.
3. Quality of workpiece delivery
The delivery quality of workpieces is the most intuitive way to reflect the strength of a mechanical processing factory. When considering the quality of workpiece delivery, you can get to know the companies that have cooperated with the machining shop before. Ask them whether the surface quality and size of the workpiece they received are the same as the drawings, etc.
Identifying quality CNC machining manufacturers is crucial to ensuring that your parts or products are manufactured with precision and reliability. Here are some key factors to consider when evaluating CNC machining manufacturers:

CNC technology originated from the needs of the aviation industry. In the late 1940s, an American helicopter company proposed the initial idea of CNC machine tools.
In 1952, the Massachusetts Institute of Technology developed a three coordinate CNC milling machine.
In the mid-1950s, this type of CNC milling machine was used to process aircraft parts.
used in various industrial sectors. However, the aerospace industry has always been the largest user of CNC machine tools; Some large aviation factories are equipped with hundreds of CNC machine tools.
In the early days of the development of CNC machine tools, CNC machine tools with continuous trajectory were mainly used for continuous trajectory control; continuous trajectory control, also known as contour control, requires the tool to move according to a prescribed trajectory relative to the part. Later, we vigorously developed point control CNC machine tools. Point control means that the tool moves from one point to another as long as it reaches the target accurately regardless of the movement route.
In order to improve the degree of production automation, shorten programming time and reduce CNC machining costs, a series of advanced CNC machining technologies have been developed.
Such as computer numerical control, which uses a small or microcomputer to replace the controller in the numerical control system, and uses software stored in the computer to perform calculation and control functions. This soft-connected computer numerical control system is gradually replacing the initial state of the numerical control system.
Direct CNC uses computers to directly control multiple CNC machine tools, which is very suitable for small batch and short-cycle production of aircraft.
