Multi-Spindle Screw Machining

Roberts Automatic can meet your needs for complex or simple parts with our wide range of multiple-spindle screw machining centers. We machine parts from steel, stainless steel, brass and aluminum.

We often hold tolerances on our screw machines that would require CNC machining or secondary operations saving you time and money.

Our screw machines are supported by our complete tool making department with a 5-axis CNC tool grinder and a wire EDM machine. This provides shorter lead times on new parts and revision changes, greater creativity, higher productivity, tighter tolerances, better quality and lower costs.
