UNISIG Drilling System Gives New Lift to Aerospace Landing Gear Production
MENOMONEE FALLS, Wis. – UNISIG, the leading manufacturer of deep hole drilling systems and technologies, engineered its new B700 Drop Bed machine to effectively generate the critical, high-precision features on large and irregularly shaped aerospace components such as landing gear struts. Conversely, the extreme flexibility of the new machine allows it to also process medium sized, more uniform shaped workpieces with minimal changeover time from one to another.
The B700 offers an expansive working range with its servo programmable workpiece headstock capability, yet it sports a streamlined overall footprint that makes for spacesaving 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 the programmable moving headstock allow the B700 to process parts as long as 157" (4000 mm) or as short as 20" (500 mm). In addition to high-precision deep hole drilling, the machine’s operational capabilities include other complex deep hole machining operations necessary in the production of other aerospace parts such as axles, beams, control rods and components for actuators. These include capabilities such as internal contouring via an optional servo bottle boring axis.
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 productively 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 cylindrical 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.
UNISIG engineers and manufactures all of its equipment in the United States with highperformance components. The company provides machines with all necessary durable tooling and machine accessories. Upon installation, UNISIG provides comprehensive training on machine operation and application support to help customers achieve production goals.
