About Us
Since 1960, Downey Grinding has provided centerless grinding services with unbeatable quality and delivery at a competitive price. We consistently maintain tight tolerances and provide superior finishes on parts of virtually any material. Our grinding capabilities include infeed and thru-feed grinding of outside diameters ranging from .030” to 2.500” including parts with multiple diameters.
To maximize production efficiency, we maintain multiple fully automated grinders, a team of handle and bellows units, along with speed controllers for Titanium part applications. A 5,000 gallon centralized oil and filtration system keeps oil clean for optimum quality and surface finish.
Quality Assurance
Our comprehensive quality assurance program is designed to meet the highest industry standards, adhering to MIL-I-45208A, MIL-STD-45662, and MIL-STD-105E to ensure precision, reliability, and compliance with stringent military and industrial requirements. By integrating Statistical Process Controls (SPC) throughout the production process, we continuously monitor and analyze key metrics to maintain exceptional quality, minimize variations, and enhance overall consistency. This proactive approach allows us to detect and correct deviations in real time, ensuring that every component meets or exceeds customer expectations for accuracy, durability, and performance.
