FROM PROTOTYPE TO PRODUCTION Keystone Precision Machining is an outstanding supplier of precision-machined parts for a wide variety of industries including defense contractors. Our 13 employees run modern CNC turning and milling centers producing parts from ferrous and non-ferrous metals and plastics. We're known for the quality parts that we produce six days a week from our 7000 sq. ft. facility located in North Wales, Pennsylvania, 25 miles north of Philadelphia. We've grown significantly in the last few years and have expanded our capacity with the addition of two new CNC milling centers and one new CNC lathe. We take quality very seriously and, over the years, have maintained the highest quality ratings with our customers. Some of our most demanding customers have designated us certified supplier which means our machined parts go directly to their stock or production line.
