Candidates for Lathe

Some parts are obvious lathe candidates. Consider the piston for a spool valve, or a hydraulic fitting. The cylindrical symmetry of these components, coupled with complex external geometry and challenging internal features, makes them permanent residents of the turning department.

Conversely, the rectangular valve body that mates with those turned parts, with its large milled surfaces, detailed pockets, and intersecting bores will never be spun on a lathe, no matter how live-tool capable that machine may be.

These are some of the reasons why our CNC machining service has turned to, well, turning. By adding live-tool (end mill) equipped CNC turning centers to our already extensive three-axis milling service, we’re able to produce better surface finish on cylindrical features and at a typically lower price for customers. Lathe also makes more efficient the manufacture of those parts that may skate on the edge of our milling capabilities. And if the goal is eventual low-volume production, turned parts are good candidates.

Have a design concept for the next best camera lens housing? How about a revolutionary drive shaft for a lawnmower, one with milled flats and threaded cross-holes? Chances are, we can deliver a turned prototype for that geometry.

Turning parts such as these offers several advantages over milling. As implied previously, long length to diameter ratios on pistons and shafts give mill operators an upset stomach. Turning a set of candlestick holders for your Aunt Martha’s 60th birthday, however, is a piece of cake on a lathe.
