For over 60 years at H.H. Arnold, we have specialized in providing our customers with a single-source solution for precision cylindrical grinding and machining. Our ability to serve a broad customer base, in a highly competitive industry is a direct result of our commitment to customer service, and constant investment in the most advanced precision grinding equipment available. Our facility is equipped with over 20 precision grinding machines and we continue to grow our capabilities. This allows our team to develop the optimal solution for even the most challenging requirements.  This resource is augmented by a machine shop that utilizes various high precision milling and turning systems.

Unlike much of our competition which can only provide specific capabilities, our resources allow us to deliver a complete solution and products that require no further processing once they leave our dock. It also allows us to offer a level of flexibility that can accommodate most requirements, regardless of volume or schedule.

As manufacturers everywhere drive to streamline their supply chains, this type of end to end service is becoming a must-have process capability. However, we take value a step further, with our efficient processes and advanced equipment resources, we can offer a combination of fast turnover and competitive prices that are unmatched in the industry.

Our position as a leader in precision grinding is also built on the skill and craftsmanship of our staff and a commitment to quality that extends to every part of our organization. From the toughest alloys to engineered plastics, ceramics, and much more, H.H. Arnold is the name to know for high precision grinding and machining.
