Guide Grinding Machine Technology Parameters
Introduction
Guide grinding machine is a precise grinding machine with high technology. It is mainly used for grinding plane parts and roller surfaces, as well as grinding cylinder mating parts and machines, such as guide rails, cylinders and other components. This paper mainly introduces the technical parameters of the guide grinding machine.
Working Principle
The grinding head of the guide grinding machine is mounted on a special sleeve. The sleeve can be manually adjusted up and down. The up and down position of the upper end of the sleeve is adjusted by a cam. When the position is adjusted, the grinding head can turn left and right.
The grinding head of the grinding machine is usually made of a hardened steel roller with a roughened surface. After grinding, the roller is run at a predetermined speed, while the grinding head moves in a spiral pattern to form a helical profile. Meanwhile, the knife-edge grinding is quickly changed according to the helical profile of the grinding path and the special angle formed by the grinding head so as to twice ensure the grinding effect.
Process Parameters
Process parameters of the guide grinding machine mainly include grinding parameters and feed speed.
The first parameter is grinding speed. The grinding speed is mainly determined by the hardness of the material being ground and the accuracy of the grinding surface. The grinding speed is usually about 2000-6000 r/min for general parts and 8000-12000 r/min for precision parts.
The second parameter is feed speed. The feed speed is generally determined by the material and the accuracy of the grinding surface. The feed speed is generally about 0.1-0.2 m/min for general parts and 0.05-0.1 m/min for precision parts.
Third, the grinding amount. The amount of grinding is mainly determined by the material and the machining allowance. The grinding amount is generally 0.01 millimeter per pass for ordinary parts and 0.003 millimeter per pass for precision parts.
Finally, the grinding time. The grinding time is mainly determined by the grinding amount. Generally speaking, the grinding time is 0.1-1.0 second per pass for ordinary parts and 0.03-0.3 second per pass for precision parts.
Conclusion
The guide grinding machine is mainly used for grinding plane parts and roller surfaces, as well as grinding cylinder mating parts and machines, such as guide rails and cylinders. The technical parameters of the guide grinding machine mainly include grinding speed, feed speed, grinding amount and grinding time. The above-mentioned parameters should be determined according to the characteristics of the workpiece being machined.
