A specialty screw machine shop is manufacturing underwater explosive casings made from aluminum bar stock for the U.S. Navy. These products must meet very strict tolerances. They use an EMCO multispindle lathe (four spindles per machine) with a water soluble coolant through the tool.
The customer needed to reduce the cycle time, reduce the amount of tooling, and reduce costs.
The EcoCut successfully decreased cycle time while eliminating three tools from the process.
