This part exemplifies the combination of precision turning and 4th axis CNC Milling. Turned on both ends with the internal bore held to a tolerance of +/-.0002. Using a rotary milling fixture the part is milled, drilled and tapped in one operation. The rotary process ensures that the true position of all features is properly maintained well within prescribed tolerances.

You can see our CNC Milling capabilities in this cover. This solid model was created in Solid Works from the customer drawing and the part was programmed using CAMWorks and its automatic feature recognition technology. It was verified using computer simulation on the solid model and sent directly to one of our FANUC Robodrill Millers for a quick and accurate creation of the cover.

This gear housing demonstrates a mix of CNC turning, CNC Milling, 4th Axis Rotary Milling and outside processing. Proper alignment between the gear teeth and the part features is paramount. This was accomplished by designing the machining process and tooling in close coordination with the gear hobbing vendor. We were able to create a tooling hole for the gear hobbing vendor which we subsequently removed in later machining operations. The finished product fit seamlessly into the customer’s end product.

This small part made of vespel, a costly raw material, takes only five operations to machine to completion. In the process design we were able to create many of the features in our rotary milling operations and make this part from the leftover material of it’s mating part. The finished product not only met, it exceeded, customer specifications at considerably less cost.

One of the front line capabilities at Dalton Manufacturing Company is CNC turning. We routinely turn castings and solid shapes with bearing bores held to tolerances of +/- .0002 of an inch. These parts are 100% inspected at the machine using a combination of precision gage pins and a Sunnen Bore G Gage. Our consistent high-quality levels have won us the highest confidence of our customers and the ability with many to provide parts on a “ship to stock” basis.
