Mitutoyo CRYSTA Apex V-Series CMM
Quality is the at the core of what we do here at PMA. We inspect every part that is produced in our shop on our Mitutoyo Crysta Apex CMM. Fully equipped with a Renishaw PH10MQ articulating head to reach tight or difficult areas without custom styli or star probes. Full first article inspection and 3rd party inspections are common place.
HAAS VF4 SS
The VF-4SS, with its 12,000 RPM Spindle, 1000 PSI spindle coolant system, and full part probing feature, allows us to have high-volume production with shortened cycle times to improve our customers experience.
HAAS VF2
Similar to the VF-4SS, the VF-2 is a high performance machine that gives us the ability to drill small, deep holes with its 1000 PSI Spindle coolant system and 12,000 RPM Spindle for extra small tooling.
Hyundai Wia L2100SY Lathe
Our Hyundai Wia L2100SY lathe is a production work horse. Equipped with a LNS bar feeder and dual spindles this machine can handle part quantities in the thousands. In addition to dual spindles the machine has Y-axis milling capabilities. Allowing PMA to produce high complexity, high volume production runs.

Life Sciences and Medical Automation
Life science automation is where Preece Machining & Assembly first began to get traction in the competitive world of machining. Unlike most of the other industry customers we serve, our Life Science clients are not required to manufacture their products in the United States. We have found that our Life science and Automation clients can achieve results locally they never thought were possible. PMA produces CNC machined components faster and of higher quality than our overseas friends. We have had the opportunity to produce end effectors, reaction vessels, and assembly fixtures for many big names in life science and medical automation companies around Boulder and the United States.
