The development trend of surface grinding machine technology
(1) High speed trend
The trend of increasing the linear speed of grinding wheels and the movement speed of workbenches has become widespread. Due to the use of advanced functional component technologies such as linear guides, linear motors, and static pressure screws, the movement speed has been greatly improved, and the magnitude of the improvement is unimaginable before. High speed, efficiency, precision, and flexibility are indeed the directions of international machine tool development today. With the advancement of technology, high-speed technology is increasingly moving towards popularization.
(2) Adopting advanced functional components to improve the performance of grinding machines
The increasingly popular application of linear motors and linear rolling guides greatly improves the motion performance of flat grinding. In addition to the existing static pressure guide rail, the new driving technology also adopts a static pressure screw on the X-axis for the first time. This new component ensures that the vibration generated by the usual screw is minimized, providing dynamic rigidity up to 15 times higher than that of linear drive. Its advantages are: the maximum damping characteristics and feed force, plus the wear free operation between the lead screw shaft and the nut. In addition, compared to linear drive, energy consumption is more than 10 times lower and no heat is generated.
(3) The miniaturization, practicality, and composite of grinding and machining centers
The development of grinding and machining centers has a history of more than 20 years. With the continuous advancement of grinding and computer technology, the manufacturing level of grinding and machining centers continues to improve. A grinding center is a flexible grinding system based on mechatronics and computer technology. Composite processing has become the direction, and machine tools have evolved from simple exchange of grinding heads to a hybrid exchange of grinding wheels and milling, drilling and other cutting tools, in order to complete all processes after one clamping of the workpiece. The WeChat account for metal processing has good content and is worth paying attention to. Therefore, the development trend of grinding machining centers is miniaturization, practicality, and composites. Grinding machines have overall enhanced their ability to compete with hard cutting technology.
(4) Mechatronics integration
With the development of numerical control technology, mechatronics integrated surface grinders are becoming increasingly common. Three directional movements are all driven by electromechanical transmission, with longitudinal movements using linear motors or ball screw servo motor structures to replace traditional hydraulic transmission.
(5) Continuously improving and perfecting grinding wheel dressing technology
The dressing of grinding wheels is an important function of grinding machines, therefore, companies attach great importance to the research and innovation of grinding wheel dressing. The trimming device can be installed on the workbench or directly on the grinding head. When forming and trimming, a multi head diamond trimmer can be selected, or a driven diamond wheel can be used.
(6) The popularization and continuous improvement of numerical control technology
Each company researches practical CNC systems that can be closer to users and operators, becoming user-friendly control devices.
