Centerless Grinding Service

What Is Centerless Grinding?

Centerless grinding is a special way to make round parts super smooth and exactly the right size. Unlike other grinding that holds parts at the ends, we use three wheels:

• A big grinding wheel that removes material
• A smaller regulating wheel that spins and moves your part
• A work rest blade that holds your part up

This means we can make parts that are perfectly round – much better than other methods!

Our Centerless Grinding Capabilities

Types of Centerless Grinding We Offer

1. Thrufeed Grinding

This is perfect for long, straight parts. Your part moves through the grinder from one end to the other, getting the same size and finish all over. Great for:

• Long bars up to 20 feet
• Parts that need the same diameter everywhere
• High-volume production runs

2. Infeed/Plunge Grinding

When your part has different diameters or special shapes, we use this method. We can make:

• Tapered shafts
• Parts with curves
• Shoulders and special features

3. Bar Straightening & Polishing

We can fix bent parts and make them super smooth with:

• Precision straightening (±0.001″ per foot)
• Surface polishing down to Ra 4 µin
• FDA-compliant finishes for food equipment

4. Legacy Part Reproduction
