CNC Machined Parts

At Progressive Machine Works, Inc., we have been devoted to providing high quality machining at competitive prices since our inception in 1922. Our many years of experience in conventional machining have paved the way to provide exceptional CNC machining services. We utilize advanced 4 axis vertical and horizontal machining centers, large and conventional lathes. We offer a variety of CNC machining processes, including milling, drilling, boring, tapping thread milling, knurling, counter boring, pocketing, reaming, and facing. Also available are CNC turning options such as contour, form, taper, and straight turning. We offer internal, external, inch, metric, and API threading, and our facility can handle numerous types of materials in various dimensions. Materials include ferrous, non-ferrous, carbon steel, iron, alloys, brass, bronze, stainless steel, and plastics. We specialize in large diameter turning jobs, accommodating diameters up to 36”, turning lengths up to 66”, and lifting capacities up to 5 tons. Our precision machinery can also cut workpieces to tolerances of ± 0.0001”. We produce volumes from small lots to large runs, with fast lead times typically ranging from 2 to 4 weeks.
