Operating Tips:

CNC Roll Grinding Machine (RGK-800, RGK-1000, RGK-1250, RGK-1600, RGK-2000)

Features:

1. This machine is special suitable for grinding working rolling and supporting rollers of the rolling mill in metallurgical industry, rolling of paper machine in paper marking industry, various press rollers used in rubber industry, metal and nonmetal press roller in printing and dyeing industries.

2. It also can finish many grinding machining, such as roller neck, cylinder, rolling body of circular cone, rolling body of cambering range, convex or concave curve shape.

3. It has high machining efficiency and high quality, perfect accuracy and so on.

4. It also has characters of excellent appearance, compact arrangement, convenient for operating, safe and reliable. Besides, a complete attachment can be supplied for choice.

5. Moving of the grinding wheel, longitudinal travel of the carriage as well as turning of workpiece are all for infinite variable, changing range of speed is very wide.

6. Dynamic and static pressure bearing has been adopted by spindle of the grinding wheel, so the spindle has high rigidity and swiveling accuracy. High and new technique and reliable necessaries have been used by the equipment. It has good technical performance and persistent.

7. The cambering range, convex or concave curve is grown by kowtow swaying mechanism of grinding wheel rack.

8. Reciprocate travel of carriage is controlled by PLC electric, it is easy to operate, the position is correct, CNC static eccentric sleeve construction has been adopted by middle and high curve grinding. It is driven by SIEMENS AC servo motor, internal automatic dynamic balancer is mounted on the spindle of the grinding wheel, so that it has performances of high rigidity and moving sensitivity.
