What is Centerless Grinding?

Centerless grinding is an important process for producing some of the most specific components across the industries we specialize in. From control rods and camshafts to hydraulics and fluid controls, centerless grinding produces the roundness and accuracy needed for any of the cylindrical parts. 

Unlike traditional cylindrical grinding where a workpiece is held by a chuck or other fitting, centerless grinding positions the workpiece without a workholding method between regulating wheel and a grinding wheel. The component is positioned on an angled support.

The regulating wheel’s speed and angle can be adjusted to provide for a feed grind or a stationary precision grind depending on what the specifications of the job requirements.  

Centerless grinding is a fantastic approach to getting a well ground surface on long, thin components and the lack of a holding device typically allows for a faster throughput. Additionally, the diametrical wheel adjustment on a centerless grinder produces a higher level of precision than the radial wheel adjustments of a traditional cylindrical grinder.

Our Experience

With over 50 years of experience producing consistent and reliable components for our clients, we have the experience that you need to feel confident in the return on your investment with us. Our machinists undergo consistent training to ensure they stay up-to-date on industry best practices. 

This is especially important in centerless grinding where successful results are dependent upon stable and predictable grinded processes. With so many factors like wheel speed, heat generation, the speed and technique of feeding objects into the machine, to take into consideration, a trained and experienced operator will get you the consistent results you need — no matter how many components need to be created.

At Asteroid Precision, we never settle into our ways, and we are always improving the quality of our work through training for our team and the acquisition of the latest centerless grinding technology. This dedication to ongoing excellence and achievement is what has earned us our reputation as a global leader in precision grinding.
