Cylindrical Grinding

Excircle grinding are the most common grinding ways, which are used on excircle grinder. the outer circle surface of grinding wheels is the working face the wheels are mainly used for valve, Drive Shaft, bearing etc. According to the material properties, surface quality and geometric precision of the workpiece, the matching grinding wheel can be chosen to the performance

Overview

Our Cylindrical Grinding Abrasives are designed to deliver high precision, exceptional surface finishes, and superior roundness in external and internal cylindrical grinding operations. These abrasives are ideal for grinding cylindrical parts such as shafts, spindles, bearings, and sleeves across various materials and industries. With optimal grain structure and strong bonding systems, our wheels offer both aggressive cutting and long service life, even under demanding production environments.

Applications

External cylindrical grinding (OD grinding).
Internal cylindrical grinding (ID grinding).
Grinding of engine components, spindles, axles, rollers, pins, and bushings.
Surface and form grinding in automotive, aerospace, and toolroom industries.
Precision finishing of hardened steel, alloy steel, stainless steel, and cast iron.

Features & Benefits
