Harmonic Drive has benefited from working with Duval in multiple ways. They always deliver on-time, their pricing is very competitive, and they provide the kind of rigorous quality that is required for our designs which have very limited tolerancing. From my experience, working with Duval feels like we are working at the same company in different departments. I can discuss projects and designs with them and decide on a course of action that we mutually benefit from—both financially and ease of manufacturability. I have recommended Duval Precision Grinding to my colleagues and to additional departments throughout our company. I recommend them because of past results, scheduling flexibility and most importantly, the quality of the product that they produce.
