Working accuracy of CG500H Cylindrical Grinder
CG500H Cylindrical Grinding Machine 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 must have a central axis of rotation. This includes but is not limited to such shapes as a cylinder, an ellipse, a cam, or a crankshaft.

CG500H Cylindrical Grinding Machine is defined as having four essential actions:
The work (object) must be constantly rotating
The grinding wheel must be constantly rotating
The grinding wheel is fed towards and away from the work
Either the work or the grinding wheel is traversed with respect to the other.
While the majority of cylindrical grinders employ all four movements, there are grinders that only employ three of the four actions.
Types
There are five different types of cylindrical grinding: outside diameter (OD) grinding, inside diameter (ID) grinding, plunge grinding, creep feed grinding, and centerless grinding.
Outside diameter grinding
OD grinding is grinding occurring on external surface a of an object between the centers. The centers are end units with a point that allow the object to be rotated. The grinding wheel is also being rotated in the same direction when it comes in contact with the object. This effectively means the two surfaces will be moving opposite directions when contact is made which allows for a smoother operation and less chance of a jam up.
Inside diameter grinding
ID grinding is grinding occurring on the inside of an object. The grinding wheel is always smaller than the width of the object. The object is held in place by a collet, which also rotates the object in place. Just as with OD grinding, the grinding wheel and the object rotated in opposite directions giving reversed direction contact of the two surfaces where the grinding occurs.
Applications
The cylindrical grinder is responsible for a plethora of innovations and inventions in the progression of science and technology. Any situation in which extremely precise metalworking is required, the cylindrical grinder is able to provide a high level of precision.[citation needed] From the automotive industry to military applications, the benefits of the cylindrical grinder are numerous.
Application
1. CG500H Cylindrical Grinding Machine is designed for grinding cylindrical or taper surface of rotational parts highly adaptable for single and small batch production;
2. Cylindrical Grinder table traverse is actuated by hydraulic means at infinitely variable speed or by hand;
3. Auto intermittent micro-infeed and rapid approach and withdrawal of the wheel head of CG500H cylindrical grinding machine can be affected hydraulically; while rough-fine-feed realized by hand wheel;
4. Cylindrical Grinder's worktable and wheel head guideways are hydrostatically lubricated;
5. Grinder's grinding wheel spindle is supported by three tilting segmented shoes;
6. Workpiece, wheel, hydraulic pump, coolant pump are driven separately by individual motors;
7. Each motion part of Grinding Machine is controlled by electric, hydraulic, mechanical interlocking mechanism, thus the cylindrical grinder can be operated with ease and safety;
