Precision Thru-feed & Infeed Centerless Grinding

Centerless Grinding. Centerless grinding is an OD grinding process. It differs from other cylindrical processes in that the workpiece is not mechanically constrained. On traditional OD machines, the work is held between centers or chucked and rotated against the faster spinning grinding wheel by an external motor usually located in a workhead.

Basics of the Centerless Grinder 233

"Basics of the Centerless Grinder" provides a comprehensive introduction to centerless grinding. Centerless grinding includes both internal and external grinding operations. During centerless grinding, a rotating regulating wheel moves a workpiece, supported by a work rest blade, along a rotating grinding wheel. This abrasive process removes a layer of material from the surface of the ...

Centerless grinding - Wikipedia

Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; the workpiece is secured between two rotary grinding wheels, and the speed of their rotation relative to each other determines the rate at which material ...

8 Principles of Centerless Grinding

Dec 08, 2016 · A downside of centerless grinding is you can't have as many multiple axes operating on the workpieces. However, there are many parts where the process addresses the limitations of machining in terms of dimensions, materials, and surface finishes. That's why we like to say that where machining ends, the centerless grinding process begins.
