    Abrasive Applications and Markets  
       
    We focus our efforts towards supplying abrasive for the surface grinding market. Our excellence and on the job performance make Jowitt & Rodgers the first choice for many manufacturers. The following list includes just a few of the markets where J&R is at work to lower costs:
       
    Production Disc Grinding  
       
    Double Disc grinding is a high production, highly accurate method of producing dual flat and parallel surfaces simultaneously in stampings, castings, and sintered metal parts. While the process can be extremely cost effective because of its speed and precision, success can only be achieved with the proper set-up and the correct abrasive. Using Jowitt & Rodger's abrasives offers significant advantages for Disc Grinding.
       
    Disc Grinding can vary from high production rates exceeding 30,000 parts per hour to only a few parts per hour on large parts involving heavy stock removal. Regardless of the production rates, there are some peculiarities of disc grinding that differentiate it from other processes, such as cylindrical and plane surface grinding. First, the face of the wheel is used. While this creates a distinct advantage in terms of accuracy and productivity, it causes some unique problems.

 Spring Button    Spring Grinding  
       
    In the last few years, spring companies across the USA, were changing to a new grinding wheel. J&R's revolutionary new grinding wheel lowered their abrasive costs, increased their production rate, and improved the quality of their springs.

Jowitt & Rodgers has developed this exciting new bond technology to support ceramic grain. This Cubitron™ grain, produced by 3M, has unique properties that can result in wheels that improve cutting speed and last longer. The savings from increased efficiencies can be dramatic.
       
    Our product is not just another new spring grinding wheel, these discs are a technologically improved ceramic grain abrasive disc wheel that consistently results in a longer operational life, reduced dressing requirements and more efficient production.
