Precision Machining

Design and build under one roof + General purpose machining

The machine shop is the heart of bringing engineered designs to reality.  From state of the art CAM driven milling centers to traditional manual lathes and mills, precision machined components are in perpetual production.  Custom machined parts for aerospace, oilfield, medical and the robotics industry keep spindles turning.  Sisu machinists have great attention to detail and the true art of machining.  They program parts using modern software tools, yet can quickly turn a part on a manual mill for a customer prototype.
