UNE 12-2 Compact Gundrilling System

Versatile, productive and reliable, the UNE 12-2 compact gundrilling system brings new levels of increased manufacturing capacity to a variety of industries, including automotive, medical and firearms. Whereas a shop may perform deep-hole drilling on Swiss automatic machine tools, a dedicated deep-hole drilling solution, such as the highly engineered UNE 12-2, significantly reduces lead times and provides a higher degree of accuracy and precision. Due to its compact design, the UNE 12-2 is easy to install in a shop’s existing CNC machining cells.

The UNE 12-2’s process monitoring and control system displays real-time machining data. The system tracks measurements such as advanced thrust power and coolant pressure and reports them back to the operator, which allows for optimization of the machine’s operating conditions. The fully programmable coolant system creates ideal temperatures on the cutting surface to eliminate thermal damage to workpieces.

The UNE 12-2 has many uses in different industries, from fuel rail components for diesel engines and transmission shafts for the automotive industry to blanks for surgical tools in the medical industry. For firearm production, the UNE 12-2 can create barrel sizes from .17 caliber to .50 caliber. With an optional barrel reamer, the machine performs two steps of the barrel blank production process.

As with all UNE series systems, the UNE 12-2 is a high-performance drilling machine that increases a shop’s productivity and lowers production costs by allowing it to bring more jobs in-house, according to the company. UNISIG’s deep hole drilling technologies are all engineered and manufactured in the United States with high-performance components. It features cast iron headstock and chip box components, cartridge spindles with premium quality bearings, and a high precision preloaded ball screw feed. Its counter rotating workpiece headstock greatly enhances concentricity, and therefore dramatically increasing accuracy of finished parts.

 

Related Glossary Terms

  • computer numerical control ( CNC)

    computer numerical control ( CNC)

    Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.

  • coolant

    coolant

    Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.

  • drilling machine ( drill press)

    drilling machine ( drill press)

    Machine designed to rotate end-cutting tools. Can also be used for reaming, tapping, countersinking, counterboring, spotfacing and boring.

  • feed

    feed

    Rate of change of position of the tool as a whole, relative to the workpiece while cutting.

  • gundrilling

    gundrilling

    Drilling process using a self-guiding tool to produce deep, precise holes. High-pressure coolant is fed to the cutting area, usually through the gundrill’s shank.

  • reamer

    reamer

    Rotating cutting tool used to enlarge a drilled hole to size. Normally removes only a small amount of stock. The workpiece supports the multiple-edge cutting tool. Also for contouring an existing hole.
