Profile Grinding

What Profile Grinding does

Profile Grinding, Inc. (PGI) is a fourth-generation, family-owned precision contract manufacturer founded in 1945 by Henry Homer and headquartered at 4593 Spring Road, Cleveland, Ohio. The company operates a single manufacturing facility (~10,000 sq ft post-2002 expansion) and produces high-tolerance cylindrical and prismatic components for industrial OEM customers. Its equipment base spans Swiss turning (Citizen L32XII, L20 Type X/IX, A-20, A32), CNC turning/milling (DN Solutions Puma 2100 SY II, Doosan Lynx 220LSY, Mori Seiki Dura Turn 2050, Brother), CNC ID/OD grinding (Mitsubishi RD23, Supertec G25P-50, Toyoda GL4i-50, Okamoto IGM-NC15), and Cincinnati/Royalmaster centerless grinders, enabling tolerances to ±0.0001 inch and surface finishes to 4 microinches Ra. Adjacent services — material treatments (heat treat, plating, anodizing, passivation, electropolishing, brazing) via partner specialists, functional testing and assembly, and inventory management for just-in-time delivery — are bundled under a single-supplier model. PGI targets manufacturers across ten verticals, with Fluid Control identified as the primary segment and Automotive, Medical, Firearms, Hydraulics & Pneumatics, Electronics, Mining & Construction, Robotics & Motion Control, Agriculture & Marine, and Appliance & Food Processing as additional verticals.

Commercially, PGI runs a direct B2B sales motion through its website, phone, and email, with quote-based per-piece pricing, no minimum order quantities, typical lot sizes of 100–5,000 pieces, and multi-year blanket purchase orders for higher-volume accounts. Pricing scales inversely with lot size due to fixed setup cost amortization; tooling charges apply for custom workholding and expedite fees for accelerated turnaround. Lead times are driven by part complexity and order quantity, with an on-time delivery rate of 98% for contract manufacturing and 95% for general manufacturing (per 2012 process improvements). Quality is supported by ISO 9001 certification (Intertek, 2024) and on-request PPAP, SPC, Certificate of Conformance, and material traceability documentation. Leadership transitioned to the fourth generation in 2017 when Rick Homer (President) and Cory Homer (Vice President) assumed daily operations; the company celebrated its 80th anniversary in 2025 with a brand identity refresh and enhanced digital presence. Revenue, headcount within the disclosed 11–50 range, and detailed customer mix are not publicly disclosed, and no outside institutional funding or M&A activity has been reported.
