Through innovative ideas & progressive attitude, VMC has become a world-class supplier.

Over the years Valley Machining grew from an Iowa area supplier of screw machine products to a Midwest supplier of screw machine and precision CNC machining. Today Valley supplies precision screw machine products, CNC lathe and CNC mill products and assemblies across North America and exports around the world.
