ACCUMAX MACHINING INC

Accumax Machining Inc. specializes in the precision manufacturing of high-tolerance mechanical components for defense applications, with demonstrated expertise in producing sleeve bearings and shaft sleeves for fluid power systems. The company’s core capabilities center on precision machining of metallic components to exacting military specifications, including tight dimensional controls, surface finish requirements, and material integrity standards critical for bearing and pump assemblies. Their work involves advanced CNC machining, grinding, and finishing processes tailored to aerospace and defense-grade alloys, ensuring reliability under extreme pressure and thermal loads. Key differentiators include their ability to deliver mission-critical, low-volume, high-precision parts with strict traceability and quality control—essential for defense-grade fluid power and rotating equipment systems. Accumax Machining Inc. has established a consistent relationship with the Department of Defense, delivering specialized components used in hydraulic and lubrication systems aboard military platforms. Their work supports subsystems requiring fail-safe performance, such as actuation mechanisms and power transmission units, indicating deep integration into defense supply chains for mechanical subsystems requiring exacting engineering tolerances. The company’s primary industry focus lies in Ball and Roller Bearing Manufacturing and Fluid Power Pump and Motor Manufacturing, where they serve as a precision component supplier rather than a full-system integrator. This positions them as a niche enabler within the defense industrial base, supporting system integrators by producing mission-critical internal components that ensure system longevity and operational readiness. Accumax Machining Inc. is a small, locally based manufacturing firm headquartered in San Jose, California, operating under a 2L corporate structure. While no formal government certifications are listed, their consistent delivery of defense-grade parts suggests adherence to AS9100 or equivalent quality management standards. Their geographic proximity to key defense contractors in Northern California enhances their responsiveness and logistical agility within the defense supply network.
