Equipment

At Preece Machining and Assembly, we specialize in manufacturing complex, high-tolerance parts for the aerospace, defense, and medical industries. Our commitment to quality is reflected in our use of advanced CNC mills, turning machines, and precision inspection tools. We understand that in these critical sectors, reliability and performance are non-negotiable. That's why we prioritize top-tier equipment and meticulous processes to deliver parts that meet the highest industry standards—on time, every time.

5 Axis Milling

DMG DMU40

The DMU 40 Series offers high-performance 5-axis simultaneous machining with speeds up to 20,000 rpm across three configurations. The swivel rotary table and B-axis range of -35° to +110° provide exceptional flexibility for complex parts. With a loading capacity of up to 300 kg and advanced cooling systems, the machine ensures high precision and long-term stability. Built with a single-piece cast iron bed and direct-driven ball screws, it delivers outstanding accuracy and reliability for demanding machining applications.

DFV 5000

The Doosan DVF 5000 is a high-precision, 5-axis vertical machining center built for the efficient production of complex, small to medium-sized parts. Equipped with a high-speed spindle, automation-ready capabilities, and a large tool magazine, the DVF 5000 enables simultaneous 5-axis machining to meet the demands of industries requiring intricate parts with tight tolerances. Ideal for applications where precision and efficiency are paramount, the DVF 5000 ensures consistent, high-quality results in every operation.

3 & 4 Axis Milling

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.

Turning

My project (1)

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.

Inspection

Zeiss Spectrum 7/10/6

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 Zeiss CMM. Fully equipped with a RDS 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.
