Large Diameter Wheels
At Action Superabrasive, our grinding wheels are commonly used in the medical, ceramic, automotive, thermal spray, fine lapping, and specialty materials industries.
Large Diameter Wheels for
Center-Less Grinding
While we offer a variety of shapes and sizes, our specialty is in large-diameter wheels, including:
- Large diameter wheels that reach up to 50” in diameter
- Center-less wheels up to 24’’ in diameter
- Single and multi-grit bands on Bakelite core that reach up to 24” wide
Equipped with this state-of-the-art machinery, you can hone the surface of a workpiece while improving part OD quality.
How it Works
Centerless grinding is a machining process whereby a workpiece is gripped between two grinding wheels that rotate in the same direction but at different speeds. The grinding wheel operates on a fixed axis that rotates, directing force downward to hold the workpiece in place and shape it.
Various Wheel Types
We offer several forms of large diameter wheels, including:
- Stahli Wheels (28” and higher)
- Hexagon Pellets
- Customizable to specifications
- Double Disc / Lapping Wheels Fine Grinding Wheels Centerless
Machines
Our machines support depths up to and including 2” (50mm). This is available for through feeding, plunge, and oscillation in order to accommodate both short and long rod manufacture requirements.

Advantages of Large-Diameter Wheel Surface Grinders
Multitasking
The center-less grinding wheel is able to multitask either by plunge or through-feed grinding. They can cut extremely hard materials and be applied to an array of materials and surfaces.
Easy Set-Up
With no need to support the workpiece in the center, loading times are quick. This allows for a continuous grinding process.
Flexibility
The lack of axial thrust on the workpiece enables you to grind different sizes and geometrical shapes, ranging from simple tube bars to complex shafts.
Quick Rates
Large diameter abrasive wheels work at a much faster rate than various other precision cutting methods, allowing you to operate at high volume.
