Is the processing center of high -speed machining high efficiency? In the past ten years, due to the continuous progress of tools, drivers, control, and machine tools, high -speed processing and efficient processing, especially high -speed hard milling, have been widely used in the mold manufacturing industry. Many occasions have been replaced by high -speed hard milling. By summarizing the mold blanks under a high -speed hard milling, the processing accuracy and surface quality of the mold not only greatly improves the processing accuracy and surface quality of the mold, greatly reduced the processing time, and simplified the production process process. The cycle reduces the cost of mold production.
The continuous improvement of the high -speed processing center is an important condition for the mold manufacturing industry to efficiently and highly process molds. Driven by driving skills, many different types of high -speed machining centers with excellent structure and excellent functions have emerged. The three -axis high -speed processing center in the mid -1990s has developed to the five -axis high -speed processing center.
High -speed processing center refers to high spindle speed (generally above 15000rpm), fast movement speed (generally above 60m/min), fast cutting speed (generally 24m/min) Small deformation. Suitable for cutting thin wall parts and widely used in aerospace, military industry, medical equipment and other fields.
High -speed spindle is one of the most critical components of high -speed processing centers. At present, the processing center of the main axis speed of 20,000 to 40000R/min is getting more and more. The main axis speed of some European high -speed processing centers has reached 60,000R/min, and the speed of the ultra -high -speed spindle above 100,000R/min is also under development. The speed, horsepower, dynamic balance, rigidity, taper hole type and thermal deformation characteristics of high -speed processing centers have a considerable impact on the rigidity and thermal stability of high -speed processing centers. In this way, the main axis and motors of the high -speed processing center are required to be combined with the two to make the main shaft of the electrical electrical shaft to achieve direct transmission without intermediate links, reducing the transmission parts, and have higher reliability.
In terms of driving method, the servo motor and roller wire driver have developed from the linear motion (X/Y/Z axis) to the current linear motor drive. The Shandong Weili Heavy Industry Machine Tool Co., Ltd. uses a linear motor and torque motor to develop the development of the processing center to meet the direct -driven five -axis processing center. Significantly improved the speed, dynamic function and positioning accuracy of the processing center.
