At SFI, Inc. we offer precision CNC machining for a range of applications across a spectrum of industries. Our newly expanded, modern ISO 9001:2015 certified and accredited facility features vertical machining centers and twin spindle turret lathes.

These capabilities allow us to machine most metals and plastics including aluminum, steel, brass, bronze, ABS, nylon, and plastic, in sizes up to 60” in length, 25” in width, and 14” in height.

We can turn components up to 9” in length, and 15” in diameter and our heavy lifting equipment can handle up to 5,000 lbs. Our machines boast features such as 4 axis, live tooling, three and four jaw chuck fixturing, and pallet workholding.

We specialize in the machining of complex parts rapidly and affordably with consistent high quality results, maintaining tolerances to ±.0001”. All phases of manufacturing are carried out on-site, utilizing such machining processes as milling, drilling, tapping, boring, and turning. These capabilities are augmented by various value added services such as rapid prototyping, complete engineering services, special packaging and assembly, as well as a number part finishing options.

Everything that we manufacture is subject to stringent quality measures; we employ advanced inspection techniques and utilize a traceable calibrated Instrumentation system. Our operation is geared for production from prototype to volume runs, with typical lead times of 2-4 weeks. For more information about our precision CNC machining services or our other value-added capabilities, please see the table below or contact us directly.
