1. Introduction of Moresuperhard GC-X3 Dressing Machine
This machine tool uses the principle of the speed difference between the dressed grinding wheel and the dressing grinding wheel to achieve the shape dressing of the dressed grinding wheel.
The machine itself can provide simple and efficient dressing for diamond grinding wheels, CBN grinding wheels and grinding wheel groups composed of multiple grinding wheels. It can dress planes, angles, arcs and profiled grinding wheels. This machine is easy to operate and has high precision. It has the following features:
1. It uses precision linear guides and ball screws, and adds a digital grating ruler (optional) so that the positioning accuracy, width size and arc size of the grinding wheel can be adjusted and measured at any time when it is being dressed.
2. The rotating A-axis uses high-precision tapered roller bearings to meet the requirements of rotation accuracy and rigidity.
3. The speed, left and right swing speed, swing stroke and the position of the center of swing of the dressing grinding wheel are all adjusted.
4. Equipped with a video measurement system with a magnification of 15 to 100 times and a 19" LCD monitor, it can measure and inspect the arc, angle and size of the grinding wheel online during work.
5. The CCD and optical size device provide easy-to-use settings and measurement of the width and position of the grinding wheel as well as inspection during or after dressing. The measurement accuracy can reach 0.005∽0.01mm.
