Quality ID Grinding Service Process Control

All ID grinding services and measurements are performed in-house at Duval Precision Grinding in a strict, climate-controlled facility. When dealing with tolerances of up to +/–0.0001, even small variations in the environment can alter measurements and the grinding process. Maintaining a temperature of 68°F guarantees that all grinding work and measurements are consistent and accurate. Once the grinding is complete, our machinists measure and recheck the parts using a state-of-the-art CMM inspection process to ensure parts meet the customer’s precise specifications. At Duval Precision Grinding, the job isn’t done until it is perfect.

Advanced ID Grinding Capabilities

Duval Precision Grinding partners with coating and plating vendors and is capable of managing the process for clients preferring a single vendor for coated and plated precision parts requiring ID grinding. For those products that require additional coating or plating, Duval will grind and measure parts for tolerance after coating or plating has been added to ensure that the final product meets your required specifications. We focus on delivering perfectly ground and perfectly measured surfaces on every ID grinding job, as we know even a minuscule burr or protrusion can cause premature wear and the loss of functionality.
