The working principle of centerless grinding was initially formed as early as in 1853.

Features: a centerless grinder is a machine tool with shortened lateral dimensions, which it is particularly suitable for being installed in small spaces and meet the requirements for simplifying various production lines and saving spaces. As the grinding wheel dressing unit is disposed at the inclined downward position above the grinding wheel, it is not necessary to keep a space for grinding wheel dressing at the side of the wheel. This space is most closely related to the transverse dimension of the conventional centerless grinders. Thus, it can greatly reduce the transverse dimension of the centerless grinding bar, and install the grinder in a small installation space, thereby meeting various requirements for simplifying the production lines and saving the space.

Strong points: cutting speed hydraulic control, adopting imported speed control valve for stepless control; guide pad structure, scientific and rational, extending the blade life; double-column structure, integrating the merits of different products; stable sawing, high accuracy; using both hydraulic and manual operations if workpiece clamping, easy to operate.

Purpose: particularly suitable for manufacturing molds and tooling and improving efficiency .

Wuxi Koyo Machine Tool Co., Ltd. introduced centerless grinder from Koyo in Japan, which has high-performance, high-precision, and easy operation, and can process grinding materials that are extremely difficult to grind and small-diameter workpieces. They can be equipped with diamond wheels.
