Centerless Grinding Wheels increase working life, stock removal.

Press Release Summary:



Available with ceramic, aluminum oxide, silicon carbide grain, and abrasive blends to maximize user grinding safety and efficacy, Norton Century45™ Centerless Wheels provide continually sharp wheel face that increases stock removal and reduces grinding times. Chemistry optimizes grain retention, which porosity for given hardness and thereby offers hard grade with softer grade performance. Design also decreases grinding noise levels.



Original Press Release:



New Norton Century45(TM) Centerless Grinding Wheels Dramatically Increase Wheel Life, Improve Stock Removal and Reduce Cycle Times.



WORCESTER, MA, USA–Saint-Gobain Abrasives, the world’s leading manufacturer and supplier of performance-engineered abrasives, has launched a new line of centerless grinding wheels to its bonded abrasives portfolio.



Norton Century45 Centerless Wheels

The newly developed Norton Century45 centerless bond platform features an exclusive chemistry that greatly improves 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, providing a range of benefits.



Norton Century45 wheels are available with ceramic, aluminum oxide, silicon carbide grain and abrasive blends to maximize user grinding safety and efficiency. These wheels reduce cycle times up to 50%, improve stock removal over 30% and increase wheel life from 30%-100% versus standard products currently on the market.



Norton Century45 provides a continually sharp wheel face that achieves over 30% more stock removal, reducing grinding times through fewer passes to achieve optimal results. Operators will generate more parts through reduced production cycle times when using Norton Century45 wheels.



Norton Century45 centerless grinding wheels also can decrease grinding noise levels by as much as 23.2dB, even when grinding hard-to-grind alloys such as Inconel 718, thus increasing operator safety. To put this reduction in context, many commercially-available foam ear plugs offer Noise Reduction Ratings in the range of 25 to 28dB.



Norton Century45 is ideal for bar grinding, fastener and tool grinding, automotive or aerospace components, as well as bearing applications. Whether in a high production grinding facility or job shop, Norton Century45 can significantly reduce grinding costs while increasing safety and production throughput.

Case Histories: Norton Century45™



1. Inconel, alloys



Application: Centerless Bar Grinding



Part Diameter & Part Length: 0.5" - 1.75" in diameter; 28 feet in length



Norton Test Wheel: 32CA60-PB45 (10"), 32CA80-PB45 (10")



Competitor Wheel: 24"x 20"x12" 80-grit silicon carbide resin wheel



Results: The Norton Century45 grinding wheel was able to increase stock removal from 0.005" per pass to 0.012" per pass, showing an improvement of 140%. The Norton wheel also produced a 100% increase in wheel life while offering a 50%reduction in cycle time. Additionally, it was observed that the Norton wheel significantly reduced noise during grind.



2. 1045 Stainless Steel (300 Series), copper



Application: Centerless Bar Grinding



Part Diameter & Part Length: 1"-2" in diameter; 10" - 144" in length



Norton Test Wheel: 3NQAC54-RB45, Norton Quantum ceramic alumina resin wheel



Competitor Wheel: 24" x 8" x 12" 46-grit aluminum oxide resin wheel



Results: With Norton Century45 grinding wheel, there was a 243% increase in G-ratio over the competitive wheel. An improved surface finish across the bar length was also observed.
