Numerical control machining centers and different types of CNC machining centers have various forms. Although the composition is different, there are many similarities. What are the main differences between high-speed machining centers and ordinary machining centers?
The composition of the high-speed machining center is similar to that of the ordinary machining center. They are composed of the main components and basic parts such as the machine bed, saddle, worktable, column, guide rail, head box, as well as hydraulic transmission components, pneumatic components, motors and electrical parts. , CNC system and other components! The high-speed machining center used for mold processing is characterized by the use of gantry structure, which enhances the rigidity of the machine tool and makes full use of the space of the processing area. Most of the machine tool materials are polymer concrete, which has good damping performance and low thermal conductivity, which is beneficial to improve the processing accuracy of the mold.
A common three-axis machining center is multi-linear motion (X / Y / Z axis) driven by a servo motor and a ball screw drive system, using modern high-speed multi-axis machining centers in high-speed machining centers, multiple linear drives, rotary motion (A And C-axis) are driven by the torque of the direct drive motor through the machining center. Some companies have developed and linear motors directly drive the torque motor to fulfill the five-axis machining center
High-speed machining centers, especially high-speed hard milling, have been widely used and promoted in the mold manufacturing industry. The integrated processing of high-speed hard milling of the mold blank under the clamp not only greatly improves the processing accuracy and surface quality of the mold, greatly reduces the processing time, but also simplifies the production process, greatly shortens the mold manufacturing cycle, and reduces the mold Production costs.
