The machine adopts the structure which moves the cross-rail. The immovable working table is placed between two machine guideways. The grinding head can move up and down along the slide which is placed in the cross-rail, it also can makes longitudinal movement follow the cross rail. When grinding the Max. OD, the workpiece OD is measurable.
Working principle of Grinding Machine The working principle of a grinding machine is quite easier to understand.. In a grinding machine, there is an electric motor which supplies the motion power to the grinding wheel with the help of a belt and pulley.. So when we start the electric motor the motor rotates at a certain rpm 150-15000 RPM, it may change according to the types of grinding ...
How does ROBELs patented contour copying device work A guiding mechanism forces the rail guiding discs to turn with the pivoting grinding unit. This stops the machine from slipping while maintaining a constant grindstone contact pressure and creating a true copy of the rail head and its profile over a pivoting range of 184 .
