Machines Combine Deep-Hole Drilling, Milling for Moldmaking
Amerimold 2017: Unisig USC and USC-M deep-hole drilling and milling machines are designed to allow moldmakers to combine operations, reduce setup time, increase accuracy and eliminate mold design restrictions associated with traditional machining centers.

The reliable and compact column-type USC machines perform BTA and gundrilling operations and can generate highly accurate holes ranging to 1.5" in diameter in large workpieces on available table weight capacities ranging to 50 tons. For increased part processing capability, optional milling spindles and rotary tables are also available.
USC-M series machining centers use two independent spindles along with rotary workpiece tables and programmable headstock inclinations to perform high-accuracy, seven-axis deep-hole drilling of hole diameters ranging to 2". Advanced CNCs provide five-axis positioning, while automatic tool changing and laser presetting contribute to the machines’ abilities to perform all required machining in one operation.
Lockheed Martin’s precision machining of composite skin sections for the F-35 provides part of the reason why this plane saves money for U.S. taxpayers. That machining makes the plane compelling in ways that have led other countries to take up some of the cost. Here is a look at a high-value, highly engineered machining process for the Joint Strike Fighter aircraft.
Cryogenic machining achieves dramatic tool life gains not by flooding the cut, but by refrigerating the tool.
The recipe for best results is simple: Start with a rigid machine, add a high pressure through-the-spindle coolant system, then combine these with the right drill geometry plus the right speeds and feeds.
