CNC cylindrical grinder is a structurally simple, operationally convenient, and adaptable cylindrical grinder suitable for grinding inner, outer cylindrical, and conical workpieces. It is suitable for use in workshops with single piece, small batch, and batch production. The workpiece rotation, outer circular grinding wheel, inner circular grinding wheel, oil pump, and cooling are respectively driven by motors. The headstock motor adopts a permanent magnet DC motor to achieve stepless speed change of the workpiece through the motor speed control plate. The longitudinal movement of the machine tool worktable can be achieved by hydraulic stepless rotation or by handwheel rotation. The lateral feed movement of the grinding wheel rack has several forms, including hydraulic movement, automatic periodic feed, and manual feed.
The operating procedures for CNC cylindrical grinding machines are as follows:
1. The installation of a new grinding wheel should be done lightly, and a soft cushion with a diameter less than one-third of the grinding wheel should be placed on it. Use a wooden hammer to gently tap it until there is no noise before starting. The operator stands beside the machine and runs it for 10 minutes without any deviation or vibration before use.
2. The machine tool needs to be cleaned, and before driving, check whether the position of the handle and travel limit block is correct.
3. When the grinding wheel approaches the workpiece, it is necessary to use a hand crank and carefully observe whether there are any protrusions or indentations on the workpiece.
4. When using workpieces, the geometric shape of the center hole should be checked. If the CNC cylindrical grinder is incorrect, it should be corrected in a timely manner. During the grinding process, it is not allowed to loosen.
5. When using the flat grinding workbench too quickly, pay attention to its endpoint. When the workpiece with a small contact area is not easily attracted by magnetic force, a stopper needs to be added. When the disk suction weakens, grinding should be stopped in a timely manner.
