Main characteristics
※ Feed and dressing movements are controlled by means of two independent driving systems.Size-metric grinding is adopted.Feed movement can be caried out both manually and hydraulically.
※ Because the machine is quipped with jumping mechanism,it is unnecessary to reset the tool after returning grinding wheelfor measurement or dressing.
※ The machine is equipped with a hydraulic switch valve to ensure safety during loading and unloading workpieces
※ A grinding spindle with 18,000 r/min.is optional for grinding bore diameter ranging from 20 to 50mm.
※ An endface grinding device is provided on the top of the workhead.There is a hydraulic interlock system between the swivel of the endface grinding device and the longitudinal movement of the worktable.

Key points to note when operating an internal grinder
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 processing quality, but also extend the service life of internal grinding machines.
