Waterjet 2nd Operations
Starting a mill part as a near-net-shape waterjet blank often saves considerable time and material, in particular for large parts requiring precision features only in specific locations. Waterjet edges are typically better than +/- .005".
We tend to maintain a vertical fixture in the Fadal, with an in-house system of jig plates to precisely locate parts lacking reference surfaces parallel to an axis.
This one-off 18" machine base plate was waterjet-cut in 1/2" 6061 aluminum, including all the holes. Second ops here were countersinking and tapping holes using the Bridgeport. This part is for practical purposes indistinguishable from a fully CNC machined part, but incurred no CNC mill programming or setup cost.
This 7" diameter, 2" thick aluminum part was waterjet cut to net shape from 2" 6061 plate, then machined on the edges in a single rotary table setup.
These parts are blanked on the waterjet including the rack teeth, which the waterjet cuts with adequate precision for the application. The hole features are done in two setups using the Fadal.
Our signature sign clamp is waterjet-cut in 3/8" steel, then edge drilled, chamfered and tapped. This is an inexpensive way to make this sort of part.
This production part is waterjet cut to net shape in 1" 6061, then drilled and tapped in two setups using the Fadal VMC. The parts nest tightly for about 2/3 the material usage vs. machining from bar.
These parts are waterjet-cut to net shape in 1/2" 6061, then milled square on two edges, with shoulders and countersinks, in simple setups.
This bespoke clevis for an art installation is a mix of waterjet parts cut in 3/4" and 1/4" stainless steel, with Bridgeport 2nd ops, and two lathe setups for the pins.
