High Precision Metal Grinding & Lapping Services

Full Service Metal Grinding Center

Our full-service metal grinding center includes:

  • 12 centerless grinders
  • 4 plunge/profile grinders
  • 6 surface grinders
  • 2 vertical double disk grinders

We have two types of through-feed centerless grinders. One design has an open architecture that allows for high throughput speeds and fast change-overs; the other is customized to hold extraordinary sub-micron diameter tolerances. Our micron level tolerance surface grinders have rapid and creep capabilities; using our specialized attachments, the equipment is capable of end feature profiles up to and including a full spherical end radius. With vertical double disk grinders, we are able to grind high volumes of small metal parts to micron tolerances.

Fast Facts About Precision Grinding Services

  • Offering unmatched grinding tolerances down to ±0.000020” (±0.5 μm)
  • Ground diameters as small as 0.002″ (0.05 mm)
  • Ground surface finishes as smooth as Ra 4 microinch (Ra 0.100 μm) on both solid parts and tubes, including thin wall tubing, long length components, and wire diameters as small as 0.004” (0.10 mm)
  • High-precision grinding of inside corners and end radii from sharp to full round while holding angle tolerances in the arc seconds, to produce profiles, forms, multiple tapers, narrow slots, all angles, and pointed metal parts
  • Capable of holding and producing geometric features including perpendicularity, squareness, parallelism, and flatness — all within arc seconds

Lapping Services

When you require highly polished part ends, extremely tight length tolerances, and extraordinary flatness unavailable by any other production method, we employ our unique in-house lapping machines. We can process both tubes and solids using our experienced lapping, fine grinding, and flat honing capabilities, allowing us to meet your precision tolerance and surface finish requirements. Additionally, our flexible production capacity enables us to meet both large and small volume needs for precision small metal parts.

Flexible Volumes

Whether you have a large or small requirement for highly polished part ends, extremely tight length tolerances or extraordinary flatness, our lapping services can meet your requirements with large lapping, fine grinding and flat honing capabilities. Our capacity may be large, but our specialty is the stress-free high precision grinding of small metal parts.

Specialized Performance

We have three types of lapping equipment, each of which offers specialized performance and easy set-up for small batch, fast turnaround. Our double disk grinders have huge throughput capacity and can handle your largest volumes. Solid parts or tubes, including thin wall tubes, can all be precision processed free of heat-affected zones and with significant surface finish improvements.
