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.

Features of multi-axis machining: (1) Reduce benchmark conversion and improve machining accuracy. The process integration of multi-axis machining not only improves the efficiency of the process, but also because the parts only need to be clamped once during the entire machining process, it is easier to ensure the machining accuracy. (2) Reduce the number of fixing devices and the floor space. Although the price of a single piece of equipment used in a multi-axis machining center is relatively high, due to the shortening of the process chain and the reduction in the number of equipment, the number of fixtures, workshop area and equipment maintenance costs have increased and decreased. (3) Shorten the production process chain and simplify production management. The precision machining of multi-axis CNC lathes greatly shortens the production process chain, and because only one job post is assigned to the machining task, it not only simplifies production management and scheduling, but also greatly improves transparency. The more complex the work piece, the more obvious its advantages over traditional production methods with decentralized processes. At the same time, due to the shortening of the production process chain, the number of products in progress is inevitably reduced, which can simplify production management, thereby reducing production and management costs. (4) Shorten the development cycle of new products. For companies in aerospace, automotive and other fields, some new product parts and molding molds have complex shapes and precision requirements. Therefore, a multi-axis CNC machining center with high flexibility, high precision, high integration and complete processing capabilities can solve the accuracy and cycle problems of complex parts processing in the new product development process, greatly shorten the development cycle, and increase the success rate.

Multi-axis machining superiority: Multi-axis CNC machining center has the characteristics of high efficiency and high precision. The workpiece can be machined on 5 sides after one clamping. If equipped with a 5-axis linkage high-end system, it can also perform high-precision machining of complex space surfaces, which is very suitable for processing automobile parts, aircraft structural parts and other workpiece forming molds.

Its biggest advantage is to make the processing of original complex parts easier, shorten the processing cycle and improve the surface processing quality. The improvement of product quality requires higher product performance. If you use a dual-turntable five-axis linkage machine tool for processing, due to the special optical effect requirements of the headlight mold, many small curved surfaces used for reflection have a high indication of processing accuracy and smoothness, especially after completion, almost a mirror effect is required. It is very easy to use high-speed cutting technology equipment and a five-axis linkage machine tool to cut the mirror surface with a ball milling cutter during processing, and it was almost impossible to achieve relatively backward processing technology in the past. The use of a five-axis linkage machine tool to process the mold can quickly complete the mold processing, and the delivery is fast, which better guarantees the quality of the mold processing, makes the mold processing easier, and makes the mold modification easier. In traditional mold processing, a vertical machining center is usually used to complete the milling of the workpiece. With the continuous development of mold manufacturing technology, some shortcomings of the vertical machining center itself have become more and more obvious. Modern mold processing usually uses ball-end milling cutters for processing. Ball-end milling cutters bring obvious benefits in mold processing. However, if a vertical machining center is used, the linear velocity of the bottom surface is zero, so the finish of the bottom surface is very poor. If four-axis or five-axis linkage machine tool processing technology is used to process molds, the above shortcomings can be overcome.

 

The above are three kinds of compensation commonly used in precision machining of CNC lathes, which bring great convenience to our programming and machining, and can greatly improve work efficiency.
