machining

Harrison Steel operates rough and finish machine equipment, giving our customers options on how cast parts are finished prior to delivery.

Our facility features three areas capable of machining castings up of 60,000 and 14,000 pounds, respectively. Our expert machine shops can meet specific tolerances from /- .75mm for rough machining to +/- .015mm for finish machining of assembly ready parts. Our Statistical Process Control (SPC) ensures we manufacture and machine each part as intended by our customer’s specifications.

The Finish Machining area incorporates the use of Master Cam with customer supplied models to generate CNC programs. We also have the capability to design and fabricate machining fixtures in house to reduce costs and lead times.
