Internal cylindrical grinder is a device mainly used to polish workpieces with shapes such as inner circular holes and inner conical holes. The difference between an internal cylindrical grinder and an external cylindrical grinder is the position at which the workpiece is polished. As the name suggests, an internal cylindrical grinder grinds the interior of the workpiece, while an external cylindrical grinder grinds the exterior.
Attention should be paid when operating the internal grinder: when polishing various workpieces, it is necessary to strictly follow the equipment instructions and operation manual to ensure the quality of workpiece processing. After the operation is completed, the internal grinder should be regularly inspected and maintained. If a malfunction is found, a dedicated person needs to inspect and repair it, and self inspection is not allowed. Regular cleaning and maintenance can not only improve machining quality, but also be a necessary step in extending the service life of internal grinding machines.
