Aggressive Grinding Service

What Aggressive Grinding Service does

Aggressive Grinding Service, Inc. is a privately held, founder-owned US precision grinding and machining job shop founded in 1988 by Lester Sutton and headquartered in Latrobe, Pennsylvania. The company operates approximately 100 grinding and machining machines across a 42,000 sq ft facility, employing nearly 100 staff across three shifts. It self-describes as North America's leader in precision tungsten carbide grinding and advanced ceramic finishing, also serving PCD grinding customers, with no disclosed competitors, resellers, or external investors.

The company's service portfolio spans nine core capabilities: CNC machining (3 & 4 axis), surface grinding (traditional, Stahli double-disc, and Blanchard rotary), centerless grinding, OD grinding, peel grinding, ID grinding, ID honing, wire EDM, and wheel dressing. It is differentiated by an equipment stack anchored by Stahli DLM-705 double-disc grinders (10x manual throughput), Okuma CNC grinders, Rollomatic and Tru-Tech 5-axis peel grinders, and AgieCharmilles wire EDM, paired with a metrology layer (Zeiss Contura G2 and Duramax CMMs, RAM Optical, Keyence wireless digital micrometers, Zeiss Surfcom NEX) feeding MeasurLink SPC for real-time quality monitoring. Achievable tolerances reach 0.000050 inches with a stated scrap rate below 1%, and centerless capacity exceeds 10,000 parts per day. The business is ISO 9001:2015 and dEKRA GREEN certified.

Commercially, Aggressive Grinding Service operates a direct B2B RFQ model with no intermediaries: customers submit drawings via web form, email, phone, fax, or mail, and pricing is quote-based on complexity, tolerances, volume, and material. Standard lead time is 3-5 days with a 24-hour expedited option, supported by redundant machine capacity and over 1,000 diamond wheels kept in inventory for fast changeover. Primary customer segments are industrial carbide manufacturers, advanced ceramic component producers (silicon carbide, silicon nitride, aluminum oxide, zirconia, zirconia-toughened alumina, boron carbide), and PCD tool manufacturers. The company maintains a partner-loyalty philosophy, explicitly refusing to compete with its customers' downstream businesses, and is supported by a documented management team spanning General Manager, Sales, Production, Quality, Engineering, ISO, and Shipping functions.

Core offering

Aggressive Grinding Service provides contract precision grinding and machining services for carbide, advanced ceramic, and PCD materials, operating approximately 100 CNC and manual machines from a 42,000 sq ft facility in Latrobe, PA. Core offerings span surface, centerless, OD, ID, peel, and double-disc grinding, plus CNC machining, wire EDM, ID honing, and wheel dressing, supported by ISO 9001:2015 certified quality inspection. Customers submit RFQs and receive standard 3-5 day turnaround with 24-hour expedited options.

Product overview

Aggressive Grinding Service provides precision carbide grinding and advanced ceramic finishing as a service-based operation rather than a software product. The company operates approximately 100 machines from its 42,000 sq/ft Latrobe, PA facility, offering a unified suite of grinding and machining services. Core capabilities span nine specialized service areas: Machining (CNC 3-4 axis machining, turning, boring, threading), Surface Grinding (traditional, double-disc, and rotary), Centerless Grinding, OD Grinding (CNC and thread-grinding), Peel Grinding (5-axis cylindrical), ID Grinding, ID Honing, Wire EDM, and Wheel Dressing. These services are supported by integrated value-added modules including real-time SPC quality monitoring using Zeiss and Keyence metrology equipment, ISO 9001:2015 certified quality management, and the company's signature rapid delivery service achieving 3-5 day standard turnaround. The service portfolio targets carbide, ceramic, HSS, and stainless steel precision components across high-volume production runs (thousands of parts per day capacity) and tight tolerance requirements (as precise as 0.000050 inches).
