Multi-Machine Linkage for Through-Feed Grinding

To enhance the efficiency of centerless grinding, reduce the labor intensity of operators, and improve product quality, Zhiyuan Robotics Company has utilized the high efficiency and suitable machining precision of through-feed grinding for roughing, semi-finishing, and finishing processes. The company's factory in Lingang, Fengxian is expected to have produced over 900 robots by the end of the year, with more than 200 for internal use and nearly 700 for shipment. Centerless grinding is suitable for batch production of slender shaft workpieces, offering high grinding precision and is widely used in industries such as automotive and machine tools.

There are two types of centerless grinding: in-feed and through-feed. In-feed grinding offers high precision but lower efficiency, while through-feed grinding is highly efficient but with relatively lower precision. Zhiyuan Robotics Company primarily uses through-feed grinding for efficient processing and achieves automated production through multi-machine linking. However, this type of adjustment requires a high level of technical expertise and practical experience.

Single-machine adjustments include machine inspection and adjustment, such as the calculation and adjustment of the workpiece center height, guide wheel dressing displacement, guide wheel tilt angle, and dressing angle. Additionally, the adjustment of tooling and fixtures is crucial, including the selection of the support plate angle and the adjustment of the guide plate. The realization of multi-machine linking involves the addition of linking mechanisms, allowance distribution, selection of grinding wheels, and optimization of the cooling system.

Adjusting multi-machine linking in centerless grinding is a complex technical challenge that requires a comprehensive consideration of the machine tool, process parameters, and collaborative work. Through meticulous adjustment, it is possible to improve machining precision, efficiency, and stability, providing a guarantee for enterprise production. With the advancement of technology, future adjustments of centerless grinding will become more intelligent and precise, promoting high-quality development in the manufacturing industry.
