USC-M Milling and Drilling Centers

For manufacturers that have an opportunity to benefit from the combination of deep hole drilling and milling operations, UNISIG offers the USC-M series. Machines maximize production by allowing the fastest deep hole drilling with milling, with 5-axis positioning, to perform a range of complex machining in a single machine and setup.

USC-M series machines offer a full range of solutions for manufacturers, including heavy weight table capacities, a rotating A-axis, automatic tool changers, and intuitive controls on each machine. Models are available in a range of capacities and options, with engineered universal (gundrilling + machining) or dedicated (deep hole drilling, milling) spindles.

USC-M Machines are available in three base configurations to meet the full range of manufacturer needs.

Universal gundrilling + milling combination spindle with quick changeover for a range of operations in a single machine

Dedicated spindles for BTA + gundrilling, and milling, for powerful machining capabilities and improved feed rates

Dedicated spindles for BTA + gundrilling, and milling, plus robust options for the ultimate in milling and drilling performance
