Centerless Grinding Wheels Increase Wheel Life, Improve Stock Removal

The centerless grinding wheels are available with ceramic, aluminum oxide, silicon carbide grain and abrasive blends to maximize user grinding safety and efficiency.

Saint-Gobain Abrasives’ Norton Century45 centerless bond platform features a chemistry that is said to improve grain retention in the wheel. Better grain retention means wheels are constructed with more porosity for a given hardness. This translates into wheels having a hard grade with the performance of a softer grade.

The centerless grinding wheels are available with ceramic, aluminum oxide, silicon carbide grain and abrasive blends to maximize user grinding safety and efficiency. These wheels are designed to reduce cycle times by as much as 50 percent, improve stock removal by more than 30 percent and increase wheel life from 30 – 100 percent compared with standard products on the market, according to the company.

Norton Century45 wheels provide a continually sharp wheel face that achieves more than 30 percent more stock removal. They are designed to reduce grinding times through fewer passes for optimal results. Operators generate more parts through reduced production cycle times when using these wheels, the company says. 

The wheels also can decrease grinding noise levels by as much as 23.2 dB, even when grinding hard-to-grind alloys such as Inconel 718, which is said to increase operator safety. To put this reduction in context, many commercially available foam ear plugs offer noise reduction ratings in the range of 25 to 28 dB. 

The centerless grinding wheels are especially useful for bar grinding, fastener and tool grinding, automotive or aerospace components, as well as bearing applications.
