The overall layout of the roll grinder adopts the structure that separated work-piece bed and the carriage bed. It is suitable for grinding work rolls and backup rolls on roll mills in the metallurgical industry, rolls on paper machines in the paper industry, and various pressure rolls in the rubber industry. Various metal rollers and non-metallic pressure rollers in the printing and dyeing industry.
This machine can complete the following tasks:
(1) Grinding cylindrical
(2) Grinding the roll surface of convex or concave curved surface
Main features of machine tools
1. The overall layout of the machine tool adopts a separate structure, which can avoid the influence of the deformationwhich caused by the weight of work-pieceon the grinding wheel bed, which can ensure the machining accuracy.
2. The bed is designed with finite element method, the rib layout is reasonable, and the material is HT300 high-grade high-quality gray cast iron.
3. The head-stockis driven by a high-performance DC motor, which has the characteristics of large starting torque and good low-speed performance.
4. The tail stockis composed of upper and lower bodies. The double-layer tail stockis convenient to adjust the accuracy of the two centers in the horizontal direction. The tail stock is equipped with an electronic display instrument for the holding force of the work-piece, which is convenient to observe the holding force of the work-piece. At the same time, according to the weight of the work-piece and the center Angle, select appropriate holding force.
5. The grinding wheel stand is one of the core components of the roll grinder. Its rotation accuracy and movement stability directly affect the grinding quality of the work-piecesurface. Our company’s grinding wheel stands draw on the strengths of others, and introduce and absorb foreign advanced manufacturing technology. Therefore, the grinding wheel stands of our roll grinders have reached the domestic advanced level and are close to the international advanced level.
6. The guide rail of the large carriage is in the form of V-flat structure and adopts the plastic static pressure technology. The movement of the large carriage has good low-speed motion characteristics, which can effectively eradicate crawling, with high movement precision and no wear.
