USK Series Knee-Type Machines

The highly precise UNISIG USK series CNC knee-type deep hole drilling machines are the best choice for shops that machine complex, highly accurate workpieces. Due to refined control of the drilling process, diameter-to-depth ratios of over 200:1 are possible. USK series machines are also particularly adept at routine and successful machining of exotic materials, including Inconel.

Several different machining processes can be completed on USK series machines thanks to the multiple machine configuration options resulting in minimal changeover. This modular option provides maximum flexibility to machine a variety of workpieces on a single machine.
