Quality Control at Every Stage of Production
At B&H Machining, quality is not an afterthought—it is the foundation of everything we do. Our quality-first mindset guides every stage of production, supported by full-time, dedicated inspectors whose sole focus is ensuring every part meets specification. We utilize advanced inspection technologies, including Coordinate Measuring Machines (CMMs) and vision inspection systems, to verify dimensional accuracy, critical features, and tight tolerances.
To ensure consistency and repeatability, we apply Statistical Process Control (SPC) to monitor key dimensions and identify variation early in the manufacturing process. This proactive approach allows us to maintain stable processes, minimize risk, and deliver reliable results across both prototype and production runs.
From first article inspection through final verification, our inspection team works closely with machinists to uphold rigorous quality standards. B&H Machining’s disciplined inspection practices, skilled personnel, and continuous improvement mindset ensure every part reflects our commitment to precision, reliability, and customer confidence.

DMG-MORI NLX2500 with Industrial RobotCoordinate Measuring Machine (CMM) Inspection Capabilities
B&H Machining utilizes advanced Coordinate Measuring Machine (CMM) technology to ensure dimensional accuracy and consistent quality across every part we produce. Our inspection capabilities include the ZEISS Contura and ZEISS C 400 CMMs, providing high-precision measurement for both small, intricate components and large, complex parts. These systems allow us to verify critical dimensions, geometric tolerances, and complex features with exceptional accuracy and repeatability. By leveraging ZEISS CMM technology, we can perform detailed part inspections, first article inspections, and in-process quality verification to ensure parts meet customer specifications and industry standards. This level of measurement capability supports tight-tolerance machining, reduces variation, and helps identify potential issues early in the production process. Our CMM inspection process plays a key role in delivering reliable, repeatable quality and ensuring confidence in every component we ship.

DMG-MORI NLX2500 with Industrial RobotKeyence Vision System Inspection
B&H Machining utilizes a Keyence Vision System to perform fast, accurate, non-contact inspection of micro machined and small precision components. This system is especially effective for verifying fine features, tight tolerances, and intricate geometries commonly found in micro machining applications. The Keyence Vision System enables high-resolution measurement of small dimensions, edge profiles, hole locations, and feature-to-feature relationships without contacting the part, helping prevent deformation or damage. Its ability to measure multiple features in a single setup supports efficient first article inspections, in-process checks, and final inspections for micro components. By integrating vision-based inspection into our quality process, B&H Machining ensures accurate dimensional verification, improved inspection efficiency, and consistent quality for micro machined parts and other precision components.

DMG-MORI NLX2500 with Industrial RobotGeneral Inspection Tools & Measurement Equipment
In addition to advanced CMM and vision-based inspection systems, B&H Machining utilizes a full range of general inspection tools to support accurate dimensional verification throughout the manufacturing process. These tools are used for in-process checks, setup verification, and final inspection to ensure parts consistently meet customer specifications. By combining precision hand tools with standardized inspection procedures, our team maintains tight control over critical dimensions and tolerances. Routine use of general inspection equipment helps identify variation early, supports efficient production workflows, and reinforces consistent part quality across all job types. These tools play an essential role in maintaining accuracy for both simple components and complex, tight-tolerance parts.

ITAR CertificationStatistical Process Control (SPC)
B&H Machining utilizes Statistical Process Control (SPC) to monitor, control, and improve machining processes throughout production. SPC allows us to track critical dimensions and process variables in real time, helping identify trends or variation before they impact part quality. By collecting and analyzing measurement data during production, our team can make informed adjustments to maintain consistent results and tight tolerances. SPC is especially valuable for repeat production, tight-tolerance components, and high-volume machining where process stability is essential. This data-driven approach supports continuous improvement, reduces scrap, and increases overall process reliability. Through the use of SPC, B&H Machining ensures greater consistency, repeatability, and confidence in every part we produce.
