Centerless Grinding Wheels: Specifically Engineered For The Job Centerless grinding is the called-for solution in many applications because it totally eliminates the need for supporting the work between centers or holding it in some other type of fixture. The two most common forms of centerless grinding are throughfeed and infeed (plunge). The centerless grinding process is used to create round parts by rotating a work wheel in conjunction with a regulating wheel. The work wheel performs the actual grinding, operating in tandem with the regulating wheel which acts as both a frictional driving and braking component. Centerless grinding is a high-precision operation and is generally utilized for high-production grinding because of its superior size, shape and finish control. But, this high-precision process is only as exacting as the wheel that does the work. Radiac centerless grinding wheels are a specifically engineered combination of grain, bond and structure, providing excellent versatility and freedom of cut.
