Spindle swing: a running cycle that often occurs in grinding, where external signals interrupt the execution of programs, grinding wheel cutting in, grinding wheel trimming, and other specialized preparation functions are used to develop a fixed cycle program. It can not only use external measuring devices, but also directly control the device to compare with the final size when connected to a suitable measuring head.
·Strengthening fixed grinding method: There are four different grinding methods according to the different shapes of the grinding parts, which have the function of controlling the inclination of the grinding wheel axis, a complete set of grinding cycles including rough grinding, rough grinding, precision grinding, and spark free grinding. The grinding wheel has the function of compensating for grinding wheel dressing, controlling the normal direction of the dressing device relative to the repaired wheel, compensating for the radius of the outer edge arc of the dressing roller, and distinguishing the system
The rate can be set to O.lum, which belongs to compact CNC systems.
The CNC system for flat and formed grinding machine tools requires flexible axis control expansion: up to 9 coordinates can be controlled, of which 6 coordinates can be linked. The minimum pulse equivalent, movement equivalent, and detection equivalent are all 0.1 μ m. The flat grinding also adopts a full closed-loop method of linear position sensors [grating ruler. induction stepper.
The modern manufacturing industry is evolving from a competition that reduces labor and product costs, improves overall efficiency and quality, to a competition that fully meets customer requirements and actively develops new products. The upgrading cycle of knowledge and technology products is becoming shorter and the batch size of products is becoming smaller, and the requirements for quality and performance are higher. At the same time, society's awareness of environmental protection and green manufacturing is constantly strengthening. Therefore, agile and advanced manufacturing technology will become an important way for enterprises to win competition. The combination of computer information technology and manufacturing automation technology is becoming increasingly close, and CNC machine tools, as an important foundation for automated flexible production, will account for an increasing proportion in the production of machine tools.
The reason why surface grinding machines adopt CNC systems relatively late compared to lathes, milling machines, etc. is because of their special requirements for CNC systems. In the past decade, with the help of CNC technology, the continuous dressing, automatic compensation, automatic exchange of grinding wheels, multiple workbenches, automatic transmission and clamping of workpieces on grinding machines have been achieved, and CNC technology has gradually become popular on surface grinding machines. At recent large-scale machine tool exhibitions in China, CNC grinding machines have accounted for the majority of the entire grinding machine exhibit, and fully functional CNC flat grinding has become the mainstream. While developing high-end CNC flat grinding, we are actively developing middle and low-end CNC flat grinding.
The CNC grinding machine industry has unique demands, and machine tool manufacturers are actively developing mechanical parts, proposing unique control requirements for the CNC system of grinding machines. Mainly includes: oblique axis control: when the axis is tilted, linear and circular interpolation can also be performed.
