The hydraulic grinder

1. This universal grinder is designed for grinding cylindrical holes and faces of work pieces. It is widely used for lot production in various types of machine building plants.

2. Machines of this type are of very massive construction, but they are designed in such a way that they can be operated as easily as machines of smaller sizes.

3. They are hydraulically operated and controlled by a single lever located at the front end of the machine. This single lever controls all functions of the machine including all movements of the wheel slide, cross-feed, starting and stopping the work of the spindle.

4. The wheel spindle is driven by a V-belt from a motor located on a bracket on the wheel slide. The cross-feed for the wheel slide is operated by a hydraulic unit.

5. The wheel head is clamped on the top surface of the table. When setting up the grinder, the wheel head can be adjusted in a longitudinal direction to suit the length of the work piece.
