CNC turning and milling composite processing manufacturers explain the selection of lathes


Four turning-milling compound machining programming technology knowledge points worthy of your learning!

The development of turning-milling composite processing technology also puts forward higher requirements on CNC programming technology, which is also a bottleneck restricting processing equipment in actual production. Due to the relatively short time required to convert milling compound processing into actual production, in the absence of professional compound processing solutions, general-purpose CAM software is usually used to plan part of the processing program, and then the processing personnel will perform manual integration to meet the program requirements The processing program of the compound processing machine tool. This solution puts high demands on the craftsman.

The truth about turning and milling compound machining simulation technology!

Turn-milling composite machining has many moving parts and complex functions, so machining simulation after programming is particularly important. Since the turning-milling composite machining of my country’s aviation manufacturing plants has been put into actual production in a short time, there is no mature simulation application technology, so most manufacturers verify and optimize the program through trial cutting, which leads to a long process. The preparation cycle and development risks and processing costs are high.

What is the difference between hard rail and linear rail in precision parts processing

The hard rail refers to the casting that integrates the guide rail and the base. When processing precision parts, the guide rail is processed according to the casting. That is, the shape of the guide rail is cast on the bed, and then processed by quenching and grinding. The bed and the guide rail are not necessarily integrated. For example, nailing steel rails to the bed after processing. Linear guides for machine tools that use hard rails usually refer to rolling guides, which are the kind used in linear modules, which are now often used in the machine tool industry. We usually refer to these types of components as “linear guides”.

What is the position tolerance of precision parts processing

The position tolerance of precision parts processing is the actual total change relative to the reference position. The position tolerance is used to limit the difference between the actual position of the measuring element on the mechanical part and the ideal position.

The characteristics of multi-axis machining in precision machining of CNC lathes

As the basis of modern machinery manufacturing technology, the precision machining technology of CNC lathes has caused major changes in the machinery manufacturing process. Compared with traditional processing technology, there are significant differences in many aspects of modern processing control, processing equipment and processing equipment. After clamping the workpiece once, the machined surface can be milled, drilled and drilled. Machining effectively avoids positioning errors caused by multiple installations, shortens the production cycle, and improves machining accuracy. Therefore, the multi-axis CNC machining technology has achieved unprecedented development.

Analysis of Numerical Control Processing Technology of Mold Core

Mold cores and cavities often have various free-form surfaces, which are very suitable for processing on CNC machine tools. The process of CNC machining is quite different from that of ordinary machining. In this paper, combined with the CNC machining process design of the mold core of the children’s product decoration, analyze and summarize the process characteristics of the mold CNC machining, and provide a reference for the mold’s CNC process design.

Methods of overhauling CNC machining centers

Due to the wear and aging of the machining center during long-term use, if you do not pay attention to maintenance, the machining center will always operate in a “sub-healthy” state. Regular maintenance of the machine tool can keep the machine tool in good running condition, delay the deterioration process, reduce the incidence of machine tool failure, and thus ensure the utilization rate of the machine tool. Although there are many types of machining centers and their structures are complex, they can be roughly divided into mechanical parts and electrical parts. The following discusses its maintenance methods from the mechanical and electrical parts.
