- What is grinding machine?
A grinding machine or grinder is an industrial power tool that is a type of machining using an abrasive wheel as the cutting tool.
- What is the centerless grinding?
Centerless grinding is a machining process. The workpiece (part) is supported between abrasive wheel, regulating wheels and work rest blade. The centerless machine uses two wheels rotate at high speed to remove materials from a workpiece (part).
Centerless is ideally for finishing the outside diameter of metal materials:
- The workpiece (part) that require a tight tolerance
- The workpiece (part) is out of round from other process
- The workpiece (part) need roundness, but without centers for chucks clamping
A centerless grinder is suitable for high production run, and it's capable to equip with different kind of automatic loading-unloading device according to the workpiece (part). It has wide applications in precision parts of aerospace, automotive, military, medical, electronic and other industries.
- What is cylindrical grinding machine?
Cylindrical grinders can be used to grind the outer diameter and shoulder end faces of cylindrical, conical or other shaped workpieces. Different from the centerless, the cylindrical grinder does not need a work rest blade to place the workpiece. The outer diameter grinding is performed between centers on the machine. Generally, cylindrical grinders are used for OD grinding. There are also universal grinders models can equipped with internal attachment to satisfy the demand of internal diameter and internal taper grinding.
