About Duval Precision Grinding

Duval Precision Grinding is a specialist grinding shop in Chicopee, Massachusetts. It works on internal diameters, external cylindrical surfaces and flat faces rather than offering a general catalogue of machined parts. Its published material scope includes stainless steel, titanium, aluminum, high-strength alloys, ceramics and PEEK, as well as coated and plated surfaces. The shop combines grinding with process engineering, custom tooling and workholding for component geometry. ID work is measured in-house, and OD programs can include grinding after a coating or plating operation. Coating and plating may be coordinated with outside vendors; those treatments are not presented as Duval in-house processes. Customers can use the official contact page to discuss drawings and grinding requirements.
