Some comments from our clients
Agilent TechnologiesTuesday, January 25th, 2011
"Our industry relies on the capabilities of companies like West Valley for helping us to develop and produce products quickly and accurately. We've sent drawings of parts to West Valley with such demanding tolerances and conditions that I was sure they would politely decline to quote. We are no longer surprised by their reasonable quotes, fast delivery and, most importantly, outstanding quality of these difficult parts."

"We routinely rely on West Valley to provide us with the parts used in our optical systems designs. The components range in size from extremely small parts used in optical fiber communications applications to large aspherical projection lenses. These are tight tolerance applications requiring careful attention to concentricity and flatness in addition to the usual machining issues. From common materials such as aluminum or stainless steel to exotics such as kovar and invar, West Valley has the knowledge and experience necessary to provide us with the quality we require."

“I just picked up [the assembly you machined] and did a quick initial assembly with the other components. I just wanted to tell you I am incredibly impressed with finish and quality. Everything bolted as it should and the door/chamber interface look spot on. Thank you for delivering such good work and catching a couple of my mistakes along the way.”
