UNISIG Spotlights New Drilling System for Aerospace Components at MMTS

MENOMONEE FALLS, Wis. – At the Montreal Manufacturing Technology Show, UNISIG Deep Hole Drilling Systems will present how its new B700 Gap Bed machine effectively generates the critical, high-precision features on large and irregularly shaped aerospace components such as landing gear struts. The company will also highlight its other deep hole drilling systems and technologies in booth 858 during the show taking place in Montreal, Canada, at the Place Bonaventure May 16-18.

Besides landing gear components, the extremely flexible B700 also processes medium sized, more uniform shaped workpieces with minimal changeover time from one to another. It offers an expansive working range with its servo programmable gap capability, yet it sports a streamlined overall footprint that makes for space-saving installations and enhanced ergonomics. This is unlike other comparable deep hole drilling machines that are often inflexible dedicated systems as well as oversized and cumbersome.

A 63" (1600 mm) swing over bed size along with a moving headstock allow the B700 to process shorter parts or longer ones up to 157" (4000 mm). In addition to high-precision deep hole drilling, the machine’s operational capabilities include other complex deep hole machining operations – such as internal contouring via its servo bottle boring axis – necessary in the production of other aerospace parts such as axles, beams, control rods and components for actuators.

For performance and superior process control, the B700 packs a preloaded drive system together with high horsepower and precisely controlled in-process feedback system for real-time monitoring. With a 126-hp tool spindle and 90-hp work spindle, the machine quickly and easily solid bores up to 8" (200 mm) diameters and counterbores to 12" (300 mm) diameters. Another productivity-enhancing feature is a 250-gpm coolant flow for excellent heat reduction, efficient chip evacuation and superior surface finish quality.

The B700 machine expands UNISIG’s extensive B-series line designed for on-center drilling of round workpieces in applications such as aerospace, defense and oil gas. In addition to standard BTA drilling methods, these machines are also capable of counterboring, trepanning and skiving and roller burnishing processes, achieving the extremely strict tolerances required by manufacturers in these and other industries.


Headquartered in Menomonee Falls, Wis., UNISIG is a world leader in the manufacture of deep-hole drilling systems and technologies for precision-focused metalcutting industries, including aerospace, automotive, energy and medical. A state-of-the-art production facility and reliable network of local suppliers allow the company to design and manufacture its BTA, gundrilling, trepanning and skiving machines as well as its tooling solutions and automation in the United States.
