Our Staff! With a combined total of over 2 centuries of experience machining every conceivable material from steel to Ultem©, our Plant II staff includes specialists in CNC milling, CNC turning, fixturing, programming, and tool path and code generation using the latest CADCAM tools and techniques.  CAD capabilities include SolidWorks, AutoCAD, and Surfcam.


The high quality of our work is our state-of-the-art equipment. This equipment includes vertical machining centers with up to 4-axis machining and up to a 30 x 16 x 28 work envelope, CNC lathes with up to 1.625” bar capacities and up to 6” chucking capacities, Tsugami CNC Swiss screw machines capable of 7-axis simultaneous machining, Mori Seiki and Emco-Meier bar-fed machining centers with subspindles and live tooling, and several cam-driven screw machines capable of high-volume production.


For the outstanding quality of our work is our comprehensive and fully documented quality system. This ISO9001:2000 certified system is maintained by a full-time Quality Manager, who ensures that all gauges are NIST – traceably – calibrated, that all procedures are followed, and that all quality assurance documentation is completed. A copy of our Quality Manual is available upon request.
