UNISIG’s UNE gundrilling machines

July 15, 2020



Ideal for manufacturers focused on high-volume/low-mix or low-volume/high-mix production environments, UNISIG’s next generation of UNE Series gundrilling machines delivers operational flexibility, improved performance, and effortless operation. Now available, the UNE Series is engineered and designed to simplify gundrilling. The UNE Series offers gundrilling solutions that are well suited for various industries, including firearms, automotive, medical, energy, defense, and aerospace.

With five models built from two frame sizes, the UNE Series can drill hole diameters from 1.4mm to 40mm and depths up to 3,000mm. The compact frame construction saves valuable floor space as well. Each machine can fit in close proximity to a shop’s existing machining center, lathe, or Swiss-style machine for efficient part-processing strategies. Built with quick and easy set-up in mind, the machines are small enough to be relocated when necessary. For added flexibility to grow with future production needs, all UNE models are robot-ready, allowing shops to add a robot whenever it fits into their budget and production schedule.

The single main spindle servo motor delivers the necessary horsepower for two spindle machines. When power is applied in single-spindle mode, however, shops can produce larger diameter holes to increase their capabilities and add new business without adding a new machine.

Unlike pressure-based coolant systems, the UNE Series features a programmable flow-based coolant delivery system designed to provide the right amount of coolant to the tool’s cutting edge. This enables an operator to confidently predict tool breakage and spend less downtime recovering an interrupted process.

Powered by Siemens, UNE Series machines feature intuitive controls that give operators a full process picture at a glance on a rich color interface with touchscreen capabilities. The control’s heavy-duty buttons also function when operators are wearing gloves.

Ergonomically designed and engineered with the building owner and operator in mind, UNE machines offer an automated door option, which can benefit companies with or without automation.

All UNE bases are FEA optimized and machined on five sides in single setup for highest overall precision. This allows for simplified installation with no foundation work required, and 3-point leveling on machines rated up to 1,000mm length.

UNE Series Overview:

  • Three two-spindle models available with maximum hole diameters of 12mm, 20mm, and 32mm. Hole diameters even greater when used in single-spindle mode
  • Two single-spindle models available with maximum hole diameters of 25mm and 40mm
  • Five rated workpiece designation options between 750mm and 3,000mm
  • Solid-carbide, brazed, and indexable gundrill tools
  • Automation ready
