JB COOK AUTO MACHINE CO LLC

JB Cook Auto Machine Co LLC specializes in precision machining and repair of commercial and industrial machinery, with a focus on heavy-duty components such as cylinder blocks for military and industrial applications. Their technical expertise lies in CNC grinding, milling, and surface finishing of high-tolerance metal parts, particularly for engine and powertrain systems requiring strict dimensional accuracy and surface integrity. The contractor demonstrates proficiency in restoring worn or damaged machine components to OEM specifications, utilizing advanced metrology and machine tool calibration techniques to ensure performance reliability under demanding operational conditions. Their specialization in cylinder block restoration suggests deep familiarity with metallurgical properties, thermal expansion management, and precision surface finishes critical for engine longevity and seal integrity. The company has delivered services directly to the Department of Defense, specifically supporting maintenance and sustainment of industrial equipment used in defense logistics and manufacturing environments. Their work for W071 Endist Omaha, though lacking detailed context, implies engagement with Army or Defense Logistics Agency supply chain maintenance operations, likely involving repair or refurbishment of mission-critical machinery. These engagements reflect a pattern of responsive, task-specific support for government facilities requiring on-site or near-site machining capabilities. Their primary industry focus is NAICS 811310, which encompasses the repair and maintenance of non-automotive industrial machinery—particularly heavy equipment used in manufacturing, energy, and defense sectors. This positions them as a niche provider of rebuild and restoration services rather than new component manufacturing, serving clients who prioritize cost-effective lifecycle extension over replacement. As a small business structured under entity code 2K, JB Cook Auto Machine Co LLC operates from Memphis, Tennessee, with no federal certifications on record. Their market presence is grounded in localized, high-skill machining services tailored to government and industrial clients requiring precision mechanical restoration.
