UNX-CP machines from UNISIG are designed to meet the challenges of off-center holes with extreme depth to diameter ratios. Cartesian and Polar positioning [CP] are combined with advanced motion control to achieve the highest accuracy in small diameter deep hole drilling. Programmable off-center continuous counter-rotation improves hole concentricity, even at depth to diameter ratios of 375:1.
Increased precision and production - our UNISIG UNE6-2i-750-CR gundrilling machine featuring in-machine automation with a dual-gripper for rapid part exchange. Reduce the time spindles are not drilling with the dual-gripper head, robot makes fewer trips back and forth to retrieve parts and exchanges parts while other spindle drills. The dual-gripper opens possibilities for dual layer pallets, increased run time, dual workpiece program cycles, and workpiece lengths up to 300mm (12in) without the need for gripper changeover.
The next evolution of automation, this UNISIG UNE6-2i-750-CR Gundrilling Machine is optimized with more advanced features to boost the dual spindles up-time, producing more parts, faster, increasing throughput. In-machine automation coupled with a part staging station as well as front and rear loading collet chucks form the trifecta of production efficiency.
For rapid parts gundrilling, whether for the firearms industry, marine industry, or other manufacturing industry, check out this overview of our UNISIG 4-Spindle Gundrilling Cell with flexible automation. Drilling one part or two different parts quicker and more efficiently than one machine alone, this automated cell system employs two UNISIG UNE20-2-1000-CR gundrilling machines. In this video you will see advanced features including our UNISIG Automated Cell Controller, dual UNISIG CBP stations, laser verification technology, 6-axis robot with End of Arm Tool change, ergonomic parts staging stations, and on-demand part inspection station.
For small diameter gundrilling, our UNE6-2i machine allows manufacturers to maintain tolerances while taking advantage of two independent spindles. Designed for what's typically medical applications, parts can be drilled easily from each end, for accuracy without sacrificing productivity or floor space.
The complete gundrill grinding solution to re-sharpen your gundrills consists of the grinder, a universal holder for gundrill tools, a digital camera, measuring software, a computer and monitor. The system is base plate mounted for tabletop or cart use.
Before UNISIG, fully automated barrel production was only possible for the largest firearm OEMs. Now, UNISIG has opened the door for small to mid-sized as well as very large manufacturers by developing scalable barrel production cells, designed for productivity and reliability.
