We don´t just machine cnc turning parts,We develop the process to ensure both quality and repeatability for every part that we deliver

ISO 9001:2015 Certified. CNC 5-axis screw machining up to 32MM and Swiss machining services up 1-1/2″ are available. Bar stock rounds, hexagons, rectangles, rods and square material forms are handled. Screw machining can be done in capacities from 1/32 in. to 1-1/2 in. Prototypes through high-volume production runs, blanket orders, cyclical production or one-offs.

Multi-axis machining enables simultaneous operations which significantly reduce cycle times (i.e. front, back, & cross working in a single operation).

Swiss turning capabilities are ideal for maintaining tight tolerances on complex shafts, bone screws, pins, rods, mandrels, medical fasteners, flanges, fittings, studs, bushings, housings,connector components, sockets & contacts and precision tubing.
