Why is the precision of the precision machining process increased?

Metal fittings, mold processing, steel processing, numerical control processing, precision machining, from the perspective of the past few years, the application range has become more and more extensive, and the effect is much better than in previous years, mainly with the assistance of mechanical equipment, naturally In terms of workmanship, the quality can also be better improved. In terms of development of many industries, if there is no mechanical equipment processing, efficiency, or workmanship speed has obvious advantages compared with other manufacturers.

The pursuit of high precision is constantly progressing in the precision parts processing industry, and the manufacturing capacity of automated equipment can be improved to create higher value for customers. The parts machining industry is very important. The company's products will be favored by the market, and the quality and precision of the products are the focus of customers' concern. Customers who choose you will not cooperate with you because they are familiar with each other. It must be that precision parts processing can meet their needs, improve the performance of equipment, improve the quality of production products, and create more profits.

In the actual production and processing, we will always encounter various problems, and some technical problems will also arise in the processing of equipment, which will make the error of CNC precision machining larger and larger. What's the reason?

When the dynamic tracking error of the parts processing equipment is too large and an alarm occurs, you can check whether the speed of the servo motor is too high; whether the position detection element is good; whether the position feedback cable connector is in good contact; the corresponding analog output Check whether the latches and gain potentiometers are in good condition; check whether the corresponding servo drives are normal, etc., and check them in time.

Of course, if the overshoot of the CNC machine tool is moving, it will also cause poor machining accuracy of the parts. For example, the acceleration and deceleration time is too short, and the speed change time can be appropriately extended; It may be that the connection between the servo motor reducer and the lead screw is loose or the rigidity is too poor, and the gain of the position loop can be appropriately reduced. It is worth noting that when the two axes of the parts processing equipment are linked together, under the influence of factors such as the axial deformation of the circle and the oblique ellipse error, the machining accuracy of the parts will also deteriorate. Among them, the deformation may be caused by the unadjusted machinery; and for the oblique ellipse error, the position deviation value of each axis should be checked first. If the deviation is too large, the position loop gain can be adjusted to eliminate it.

Various factors may cause changes in the machining accuracy of precision parts, which requires our technicians to master more professional knowledge. Machining enterprises are also highly dependent on talents, and enterprises must constantly introduce new At the same time of equipment, it is also necessary to cultivate talents in various aspects, so that the product accuracy of enterprises can keep up with the needs of the times.

Many parts and components have certain shortcomings. For example, some parts do not meet the requirements in appearance, and some have certain limitations in their scope of application. In short, these parts themselves have certain defects. , in the process of use, it will bring certain problems and troubles to its own industrial production. The parts processed by CNC precision machining can overcome these problems well, so as to excavate the unique value of the parts themselves.

Many medium-sized parts also need to be assembled, so the manufacturers of precision mechanical parts will reprocess according to such needs. After processing various parts, we can get parts that are more suitable for us, so In order to make these products serve themselves better, CNC precision machining has brought a pivotal significance to life and production.

Hardware and machinery parts also have product surface or shape that does not meet the corresponding requirements, and this workpiece will also be used for processing. This process is carried out on the parts, generally through precision turning, grinding and other operations. It is often possible to form a certain smooth surface on the surface of the parts made of non-ferrous metal materials, such as the mirror effect we often say. The shape and position of the parts after the machining process in the production of mechanical parts can also meet the geometric tolerances required by the drawings, which can well solve some problems caused by industrial production.
