Bars

We are able to straighten bars ranging from 0.125” to 1.250” in diameter. Our machines have the capability to handle about 10 inch to 12 foot bar stock. For grinding, we are able to manage up to 24 feet of solid bar or up to 14 feet long and 10” thick tubing.

Centerless Grinding

Centerless grinding is used when a round finish is desired with tough dimensional tolerances. We’re able to handle any quantity. We offer infeed grinding and are able to process through-feed grinding up to 24 feet long. Our weight limit is up to 1,620 pounds per bar.

CNC Capabilities

Our cylindrical CNC grinding capabilities are setup for single or multiple concentric diameters. We also perform roller or large shaft repairs. Cylindrical grinding can be performed for taper grinds and radius grinds as well. We perform CNC external and internal thread grinding on any type or lead with single or multiple starts. Our process automatically calculates any shrinkage or over-burn. We offer precision grinding, carbide grinding, ID grinding, OD grinding and internal grinding to meet the many varying and ever-changing needs of our customers.

Flat Grinding, Honing and Lapping

We are able to meet close tolerance requirements and necessary flatness in each of these capabilities. Flat grinding focuses on the surface finish, while honing is best for cylindricity. We also do finishing work on any metal material through lapping.

Make Complete

Some clients prefer a complete product, finished and supplied. We’re able to meet those requests as well.
