About Chicago Mechanical Polishing

Polishing is one of the most exacting finishing steps in industrial manufacturing. Surface roughness targets are measured in micro-inches, finish standards run from ASTM B912-02 to ASME BPE to SEMI F19, and the right method depends on the substrate, geometry, and end-use environment.

Chicago Mechanical Polishing consolidates that intake. One specification submission is routed to a finishing facility with the equipment, accreditation, and material expertise to meet the spec across Illinois, Wisconsin, Indiana, Michigan, and Iowa.

Electropolishing, mechanical polishing (rotary, belt, buffing, lapping), chemical-mechanical polishing (CMP), vapor polishing, vibratory polishing, edge / face / thread / weld / assembly polishing, and substrate-specific work on stainless steel, sapphire glass, and silicon wafers.

Finishes are produced to the standard named on the purchase order: ASTM B912-02, ASTM E1558, ASME BPE, SEMI F19, ISO 15730, or the customer's own internal spec.

1. Specification intake. Material, geometry, target Ra / flatness, finish standard, quantity, and turnaround.

2. Engineering review. Method, abrasive grade, and acceptance criteria are confirmed against the spec before the part ships.

3. Controlled processing. Finishing performed at an accredited shop with in-process profilometer checks.

4. QA + return. Final Ra and flatness logged; parts cleaned, passivated where required, and returned on a logged carrier.

Coverage spans Illinois, Wisconsin, Indiana, Michigan, and Iowa: Illinois, Wisconsin, Indiana, Michigan, and Iowa. Dedicated landing pages exist for 31 metropolitan areas, but parts are accepted from any address within the region; the cities above are not the boundary of the service area.
