What is CNC External/Internal Grinding Machine?

A CNC (Computer Numerical Control) external/internal grinding machine is a specialized machine tool that is used for grinding the external or internal surfaces of cylindrical or conical parts. The machine typically consists of a grinding wheel, a workholding device, and a CNC controller.

The CNC external grinding machine is used for grinding external surfaces of cylindrical or conical parts. The workpiece is typically held between centers or in a chuck and rotated while the grinding wheel is fed against the surface to remove material.

The CNC internal grinding machine is used for grinding internal surfaces of cylindrical or conical parts, such as bores and cylinders. The workpiece is typically held in a chuck and rotated while the grinding wheel is fed into the bore to remove material.

The CNC controller controls the movement of the grinding wheel and the rotation of the workpiece to achieve the desired shape and finish of the part. It also controls the speed of the wheel and the feed rate of the grinding wheel, which can be programmed according to the specific requirements of the part.

CNC external/internal grinding machines are used in various industries such as aerospace, automotive, and power transmission. They are known for their high precision, high productivity and ability to grind complex shapes and profiles. The CNC control allows for precise control of the grinding process, and the ability to automate repetitive operations.

Overall, the CNC external/internal grinding machine is a specialized machine tool that is used to grind the external or internal surfaces of cylindrical or conical parts with high precision and efficiency. Its CNC control allows for precise control of the grinding process, and high productivity.
