Several of the helicopter’s drivetrain components are gundrilled to produce hollow centres, which reduces mass while maintaining high rotational rigidity.
The 1536T has two gundrilling spindles with each spindle on an independent slide. An operator control panel is installed on both sides of the machine, enabling each gundrilling spindle to be independently controlled. This provides the end user with the flexibility to run two different parts simultaneously.
The machine has a 1.5 inch (38mm) diameter gundrilling capacity and a 36 inch (914mm) slide travel. It features steel box ways and hand-scraped mating components (instead of linear guide ways and milled surfaces). This results in superior vibration damping, extended tool life, and improved surface finish.
DeHoff gundrilling machines are designed and manufactured by Kays Engineering in Marshall, Missouri, USA.
