How high is the high-speed machining efficiency of Dongguan CNC Precision Machining Factory?

Is the machining efficiency of the high-speed machining center at Dongguan CNC Precision Machining Factory high? In the past decade, due to the continuous progress of cutting tools, drives, control, and machine tools, high-speed machining and efficient machining, especially high-speed hard milling, have been widely applied and promoted in the mold manufacturing industry. Many occasions have been replaced by high-speed hard milling. By using high-speed hard milling to comprehensively process the mold blank in one clamping process, not only has the machining accuracy and surface quality of the mold been greatly improved, the processing time has been greatly shortened, and the production process has been simplified, This significantly shortens the mold manufacturing process Cycle time, reduce mold production costs

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

High speed machining center refers to a high spindle speed (usually above 15000rpm), fast movement speed (usually above 60m/min), and fast cutting speed (usually above 24m/min), which results in high machining efficiency, good smoothness, and small deformation of the workpiece due to cutting force. It is suitable for cutting thin-walled parts and is widely used in fields such as aerospace, military, medical equipment, etc

High speed spindle is one of the most critical components of high-speed machining centers. Currently, machining centers with spindle speeds ranging from 20000 to 40000 r/min are becoming increasingly popular. In some European high-speed machining centers, the spindle speed has reached 60000 r/min, and ultra high speed spindles above 100000 r/min are also being developed. The speed, horsepower, dynamic balance, stiffness The type of cone hole and thermal deformation characteristics have a significant impact on the stiffness and thermal stability of high-speed machining centers. This requires the spindle and motor of the high-speed machining center to be integrated, enabling direct transmission of the electric spindle without intermediate links, reducing transmission components, and improving reliability

In terms of driving methods, from linear motion (X/Y/Z axis) servo motor and ball screw drive to current linear motor drive, rotary motion (A, C axis) adopts direct drive torque motor. Shandong Weiwei Heavy Industry Machine Tool Co., Ltd. has developed the machining center into a direct driven five axis machining center through linear motor and torque motor, significantly improving the travel speed, dynamic performance, and positioning accuracy of the machining center at Dongguan CNC Precision Machining Factory
