HYDRAULIC CYLINDRICAL GRINDING MACHINE
MAKE DINESH SCIENTIFIC MODEL DS-HCGM-5500
PRODUCT DESCRIPTION
The cylindrical grinder is a type of grinding machine used to shape the outside of an object. The cylindrical grinder can work on a variety of shapes, however the object a central axis of rotation. This includes but is not limited to such shapes as a cylinder, an ellipse, a cam, or a crankshaft. Most commonly, cylindrical grinding is used for grinding pieces with a central axis of rotation, like rods and cylinders. This process involves using a cylindrical grinder, which is a type of machinery categorized by rotation style and wheel device.
FEATURES:
- Low on maintenance
- Smooth functioning
- Ease of usage
