Certificate of Compliance 

Duval Precision Grinding can provide a Certificate of Compliance (CoC) proving that the part supplied or grinding service performed meets all required specifications.

Statistical Process Control

Statistical process control (SPC) uses statistical methods to achieve the consistent production of parts, focusing on early detection of issues and the prevention of problems. Duval Precision Grinding uses SPC to monitor and control every process, be it refurbishing, coating, or precision grinding a part. If effectively applied, SPC enables the consistent delivery of client parts with minimal to zero rework or scrap.

100% Inspection Reports

Duval Precision Grinding offers 100% inspection reports. To provide a 100% inspection report, an expert machinist inspects and then completely documents every dimension of a part.

First Article Inspection Report 

First article inspection reports are a service Duval Precision Grinding offers clients to ensure that, as the job moves on the shop floor, the production work meets all requirements. The process includes inspection of the the first part and approval by the customer before the job proceeds.

In addition to these certifications, Duval Precision Grinding voluntarily complies with DOT 49 CFR Part 40, and has developed and implemented a DOT workplace drug and alcohol program. The program has clear policies, provisions for education and training, drug and alcohol testing, and referral for evaluation and treatment when necessary.
