Precision, value, and on-time delivery are the hallmarks of the manufacturing services we provide at H.H. Arnold. For over six decades we have been committed to providing superior customer service, and a level of flexibility that can accommodate the most challenging project requirements.

Our milling capabilities are ideally suited for a diverse range of applications; this includes everything from a prototype, to large-scale blanket orders. We operate high precision machining systems that feature a work envelop of up to 20” in length, 40” in width, and 25” in height. Engineered for robust performance, our milling machines are designed to power through materials that are difficult or impossible to machine economically on lesser systems. When this capability is combined with our precision grinding resources, we can achieve ultra-precise surface finishes and tolerances that can meet the needs of virtually any application.

As a true full-service machine shop, our expertise and equipment resources extend well beyond the machining and grinding phase of a project. On the front end, we can provide engineering support, reverse engineering, and in-house CAM programming. On the back end we handle all deburring and cleaning, our quality department will prepare QC reports and is equipped with a broad range of test and inspection equipment, to ensure and verify all dimensional specifications, and full compliance with the most stringent industry standards.

Each of our departments and our entire staff operate through a culture of quality. We apply lean methodologies and common sense processes to enhance every phase of production. The results have been a history of success and return customers who have placed their trust in our ability to deliver on our promise of uncompromising quality.
