Job shops can easily add gundrilling to their in-house capabilities with the UNE series of gundrilling machines. These machines have a compact footprint and short lead time, while maintaining the accuracy that UNISIG is known for.

Find Machines    >

UNI single and multiple spindle production machines are capable of BTA or gundrilling, and are often paired with automation capabilities to result in production part manufacturing with extremely high accuracy.

Find Machines    >

These BTA drilling machines produce on-center holes in round workpieces, and can handle long workpieces with confidence.

USC Large Capacity BTA Machines

USC column-type machines drill precise holes in non-round workpieces up to 50 tons. USC machines are robust, capable machines, yet have a compact footprint.

Find Machines    >

USC-M drilling and machining centers allow mold manufacturers to perform multiple operations in a single setup, drastically improving throughput and removing design restrictions.

Find Machines    >

USC-TS machines use multiple spindles to BTA drill the thousands of accurate holes required by heat exchanger tube sheets, maximizing production efficiency for these energy applications.

UNR Reaming Machines

UNR reaming machines start with the precision technology of gundrilling machines, and are equipped to perform the reaming process, which creates a smooth, accurate hole in the rifle barrel blank manufacturing process.

Find Machines    >

After gundrilling and reaming, R-series machines use servo-driven motors for a controlled rifling process, resulting in high-precision blanks ready to be finished into rifle barrels with unmatched accuracy.
