Centerless Grinding and Polishing
|
|
|
|
|
|
From soft plastic and aluminum to hardened steel and hard chrome, we centerless grind a diverse range. On our centerless grinders, any custom grinding requirement can be handled efficiently for prototype or large production runs. We perform both thru-feed and end-feed plunge grinding to offer smooth super fine finishes up to 4 micro finish.
Using many types of grinding wheels in the production process, we achieve customer specified tolerances, smoothness, and uniformity in every part. Bar stock, tubing, shafts, and several other cylindrical components of diameters from 1/32" to 2 1/4" can be accommodated on our Cincinnati grinders. Standard electric polishing machines at our job shop polish aluminum, brass, stainless steel, and steel parts to mirror-like finishes. The efficiency of our in house tool grinding operations not only increases the durability of your tool, but also saves tooling costs.
