How high is the high-speed machining efficiency of CNC precision machining factories?

Is the machining efficiency of the high-speed machining center of the CNC precision machining factory high https://www.machining-custom.com/blog/cnc-machining-what-is-a-high-speed-cutting-cnc-milling-machine.html? In the past ten years, due to the continuous progress of cutting tools, drives, controls and machine tools, high-speed machining and high-efficiency machining, especially high-speed hard milling, have been widely used in the mold manufacturing industry And promotion. Many occasions have been replaced by high-speed hard milling. Through high-speed hard milling, the mold blank is comprehensively processed in one clamping, which not only greatly improves the machining accuracy and surface quality of the mold, greatly shortens the processing time, but also simplifies the production process. , thus significantly shortening the mold manufacturing process. Cycle time, reducing mold production costs.

The continuous improvement of the working performance of high-speed machining centers is an important prerequisite for efficient and high-precision machining of molds in the mold manufacturing industry. Driven by drive technology, many types of high-speed machining centers with innovative structures and excellent performance have emerged. In the middle and late 1990s The emerging three-axis high-speed machining center has now developed into a five-axis high-speed machining center.

High-speed machining center refers to the high spindle speed (generally above 15000rpm), fast moving speed (generally above 60m/min), fast cutting speed (generally above 24m/min), so that the processing efficiency is high, the finish is good, and the workpiece is not affected by cutting. Small deformation caused by force. Suitable for cutting thin-walled parts, widely used in aerospace, military, medical equipment and other fields.

High-speed spindle is one of the most critical components of high-speed machining centers. At present, machining centers with a spindle speed of 20,000 to 40,000r/min are becoming more and more popular. The spindle speed of some high-speed machining centers in Europe has reached 60,000r/min, above 100,000r/min The ultra-high-speed spindle is also under development. The speed, horsepower, dynamic balance, stiffness, taper hole type and thermal deformation characteristics of the high-speed machining center have a considerable impact on the stiffness and thermal stability of the high-speed machining center. This requires high-speed machining The central spindle and motor are combined into one, so that the electric spindle can realize direct transmission without intermediate links, reduce transmission parts, and have higher reliability.

In terms of drive mode, from the linear motion (X/Y/Z axis) servo motor and ball screw drive to the current linear motor drive, the rotary motion (A, C axis) adopts a direct drive torque motor. Shandong Weili Heavy Industry Machine Tool Co., Ltd. The company develops the machining center into a direct-driven five-axis machining center through linear motors and torque motors. It significantly improves the travel speed, dynamic performance and positioning accuracy of CNC precision machining centers https://www.machining-custom.com/cnc-machining/.
