UNISIG Gundrilling Machines
Our UNE Series is a versatile line of precision gundrilling machines designed to help manufacturers produce deep, straight, high-quality holes with exceptional accuracy and repeatability. Engineered for both job shops and production environments, UNE machines combine a compact footprint with a broad range of drilling capacities, intuitive operation, and automation-ready configurations. Compatible with indexable, brazed, and solid carbide gundrills, the UNE Series provides the flexibility to support everything from prototype work to high-volume production while delivering the reliability and performance expected from UNISIG deep hole drilling technology.
Assemble to order
UNISIG’s assemble-to-order program gives manufacturers the flexibility of a configured machine with significantly shorter lead times. Rather than building every machine from scratch or stocking fixed configurations, UNISIG maintains inventory of major UNE Series components that are assembled to each customer’s specifications after an order is placed. This streamlined approach reduces delivery times, improves manufacturing efficiency, and ensures customers receive a machine tailored to their application without compromising quality, performance, or long-term serviceability.
UNISIG GR-2 Gundrill Grinder
The GR-2 Gundrill Grinder is engineered specifically for precision gundrill grinding. Designed to produce accurate, repeatable sharpening results, the GR-2 combines precision machine construction, integrated inspection, and proprietary GrindView software to help manufacturers improve process consistency, extend tool life, and gain greater control of deep hole drilling operations. GrindView provides visual inspection, measurement, recipe management, and guided grinding workflows developed specifically for gundrill applications. Operators can verify cutting geometry, compare results to established standards, and produce consistent sharpening results while gaining greater insight into drilling performance and overall process control.
