Features
- CNC roll grinding machine overall layout adopts separated structure, which can avoid the influence of deformation caused by the weight of workpiece on the bed of grinding wheel holder on machining accuracy.
- The bed is designed by finite element method, with reasonable layout of ribbed plate, and the material is made of HT300 high grade high quality gray cast iron.
- The headstock of the roll grinder is driven by a high-performance DC motor, featuring a large starting torque and good low-speed performance.
- The tailstock consists of upper and lower bodies, the double-layer tailstock is convenient for adjusting the accuracy of the horizontal direction of the two centers, and the tailstock is equipped with an electronic display meter of the workpiece holding force, which is convenient for observing the holding force of the workpiece, and at the same time, according to the weight of the workpiece and the angle of the centers, the appropriate holding force can be selected.
- The grinding wheel holder is one of the core components of the roll grinder, and its rotary accuracy and smoothness of movement directly affect the grinding quality of the surface of the workpiece. The grinding wheel holder of Minnuo’s roll grinding machine has reached the international advanced level.
- The large drag plate guide rail is in the form of V-flat structure and adopts the paste plastic static pressure technology, the movement of the large drag plate has good low-speed movement characteristics, which can effectively eradicate the crawling, and the movement has high precision and no wear and tear.
Applications
- CNC roll grinding machines can accomplish the grinding of cylindrical, medium-convex or medium-concave curved roll surfaces.
- It is widely used for grinding work rolls and support rolls on roll machines in the metallurgical industry, rolls on paper machines in the papermaking industry, various kinds of pressure rolls in the rubber industry, and various kinds of metal rolls and non-metal pressure rolls in the printing and dyeing industry.
