1. The use and adjustment of the bed
The bed is a box-shaped casting. The front part of the bed is used as an oil pool. The electrical equipment is placed on the rear right part of the bed, and the oil pump equipment is installed on the wall at the back of the bed.

2. The use and adjustment of the workbench
The working table is mainly composed of an upper table and a lower table. Loosen the hexagon socket screws of the two pressure plates on the upper table, and roll the adjustment handle. The upper table can be reversed within a regular range to adjust the taper of the workpiece. After the upper table has turned to the desired point of view, the hexagon socket screws of the two pressure plates must be tightened before grinding. The label on the right pressure plate has two scales, one for taper and the other for share. When the upper table rolls more than 6 degrees, the grinding wheel holder must be turned to a certain point of view to avoid collision between the tailstock and the grinding wheel holder.

Causes of vibration marks on CNC cylindrical grinder
1. Vibration of the workpiece: In addition to the influencing factors of the motor, pulley and belt, the worse the rigidity of the workpiece-thimble system, the greater the friction force of the grinding wheel on the workpiece, the greater the vibration of the workpiece. The poor contact between the thimble and the center hole of the workpiece, such as the center hole has a polygonal shape, the contact area of ​​the cone is small, or the tail of the thimble does not fit well with the cone hole of the headstock and tailstock, which will also cause the workpiece to vibrate. If the horizontal and longitudinal feeds are too large, and the working surface of the grinding wheel is too blunt, it will cause the workpiece to vibrate and produce ripples.
2. Uneven wear of the working surface of the grinding wheel or blunt grinding of the grinding wheel, system vibration and uneven hardness of the grinding wheel can all cause vibrations to produce ripples.
3. Grinding wheel vibration: If the balance of the grinding wheel and the various parts of the driving grinding wheel is not well balanced, or the operation is uneven, it will cause the grinding wheel to vibrate. The main reason is the poor balance of the grinding wheel, and the second is the imbalance between the motor and the belt pulley driving the grinding wheel. The thickness of the transmission belt is uneven and the length of the belt is not uniform. If it is too large, it will cause ripples when the grinding wheel rotates.

Pay close attention to the contact between the grinding wheel and the surface of the workpiece when operating the CNC cylindrical grinder. When the surface of the workpiece is just in contact with the grinding wheel, a continuous hissing sound can be heard, the water marks on the surface of the workpiece can be taken away by the rotating grinding wheel, and a faint spark can be seen at the same time, and the coolant can be added at this time. The cooling liquid should be a saponified liquid with a higher concentration, and it must be strictly cleaned and filtered before use. Then feed, each feed is 0.005mm/per double stroke. When the spark disappears, the grinding is completed. At this time, press the lateral feed handwheel to the feed direction to make the grinding wheel slightly press into the workpiece, but not feed, which is equivalent to polishing the workpiece once to further improve the grinding Surface Quality.
