External Grinding Machine

OD grinding is grinding occurring on external surface 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.


Overview

The external grinder is a type of grinding machine used to shape the outside of an object. The external 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.

Cylindrical grinding is defined as having four essential actions:
1、The work (object) must be constantly rotating
2、The grinding wheel must be constantly rotating
3、The grinding wheel is fed towards and away from the work
4、Either the work or the grinding wheel is transversed with respect to the other.

Grinding head section

The machine adopts a precision spindle with minimal spindle runout, and comes with a standard grinding wheel. Customized or optional shaped grinding wheels are available based on specific needs.

Clamping part

The workpiece is held by a precision clamp, which has high precision. Compared with roller clamp, it can ensure the finish of workpiece surface and leave no clamping marks after grinding.

Operating handle

The left and right feeds are controlled by a hand bar, while the front and back feeds are controlled by a hand wheel. With the assistance of a positioning device and precision digital display, the grinding wheel feed can be precisely controlled.

Digital display section

The machine is equipped with two-axis digital display with an accuracy of 0.001mm, which assists in daily grinding control and ensures precision workpiece grinding.

Angle plate

The machine is equipped with a large angle plate with a range of positive and negative 45 degrees, which allows for flexible angle adjustments to meet the needs of workpiece grinding at different angles.

Standard configuration

The machine comes with a water tank and cooling device, one high-brightness LED work light, one trimming seat, one circular trimming seat, and a set of hex wrenches and tools.
