Accu-Turn, Inc., located in Southeast Wisconsin, is your one-stop supplier for all your machining projects. We run sand castings, die castings, permanent mold, and solid stock. We also machine copper, brass, milled steel, and many different types of material. We have quality suppliers for all aluminum machining casting types, as well as suppliers for welding, stamping and plating. We have many CNC machines and support equipment. You can view a list of our equipment from the Equipment page.

Accu-Turn, Inc. delivers quality finished goods, and all of our inspection equipment is sent out for certified calibration: a coordinate measuring machine, various calipers, thread gages, pin gauges, and micrometers. Every job has a routing sheet that follows the job through our shop. Our routing sheets inform the operator what needs to be inspected, how it needs to be inspected and how often, during a run. Our quality department performs first, and last piece inspection along with random spot checks on the floor to make sure the job is running to print.

Today’s competitive market demands that machining firms stay current with the latest innovations and technology being made in the drilling, tapping, turning and milling industries. Equally important is the expertise of an experienced work force—together, our people have over 200 years of precision machining experience.

As a reliable machine shop that has been in business for over 30 years, we ensure quick turnaround and flexible machine schedules with a personal touch to all our customers, whether producing a one piece prototype or a large production run.
