A CNC centerless grinder allows precise control over grinding operations, ensuring accuracy, repeatability, and consistency. You can program CNC centerless grinders to grind relatively complex shapes with little to no setup changes. As a result, these grinding machines are well-suited for executing shorter job lot sizes and vast …

Precision grinding is the process of removing metal from a workpiece to achieve a specific size, shape, or surface finish. Surface grinding is a type of precision grinding that is used to create flat surfaces on metal workpieces. This process involves using a grinding wheel to remove tiny bits of material from the surface of the workpiece until it is smooth and flat.

Figure 1: Schematic of simple creepfeed grinding operation. The tangential force is the force required to maintain the wheel speed while it is engaged with the workpiece under the given frictional and cutting forces. It is the sum of the abrasive cutting forces (i.e. forces required to remove material) and frictional forces between the grains ...

The workpiece is moved past the grinding wheel in a table-fed or centerless grinding operation. The workpiece is moved past the grinding wheel either manually or by power feed. The grinding wheel is composed of abrasive grains held together in a binder. These abrasive grains act as cutting tools, removing tiny chips of material from the workpiece.

Grind-to-grind time for a wheel change is about 15 seconds. "Whenever possible, we mount two different grinding wheels on the arbor. This adds to the capacity of the tool changer and often enables us to skip a wheel change. The CNC program simply repositions the second wheel for additional operations," Scott says.

During mill operation, grinding balls wear and are reduced in size. In doing so, the grinding characteristics change. The extent of wear would depend on the characteristics of the rock present, such as surface hardness, density and composition. The abrasive action on the surface of the balls increases with time.

A larger abrasive grinding wheel; The beauty of precision centerless grinding is that the workpiece is held in place by the pressure of the rotating wheels. No fixturing is required, so the setup is simple and turnaround times are fast. And because the workpiece is rigidly supported, there is no deflection during the grinding operation.

Grinding machines or tools use an abrasive wheel to remove metal from the workpiece. When the wheel rotates, it cuts material off the workpiece by cutting. The amount of material removal is dependent on factors like abrasive material and grit selection. The video below explains how to select the right abrasive.
