HIGH PRECISION PUMP SHAFT PRODUCED BY MICRO TOOL COMPANY

With over 50 years of experience, our extensive knowledge of modern CNC Turning and high precision CNC grinding gives us the competitive advantage.  This project required us to aggressively rough machine the shaft and then finish turn and CNC grind to tolerances of +-.0002” and bearing journal concentricities of .0002” maximum runout.   Finish grinding was performed on our super precision Kellenberger CNC grinder.
