Twin-spindle gundrilling machine

Auto sales finally got back above pre-recession levels in 2014 with August sales reaching a seven-year high. After six long years, sales levels have matched 2007’s pace. More importantly, several research groups expect 2015 continue to grow. Today’s Motor Vehicles allows marketers direct access to this healthy industry with continued growth.

Marshall, Missouri – The Eldorado M75-48T two-spindle gundrilling machine, with 48″ (1,219mm) of slide travel, offers 60% more slide travel than the standard Eldorado model. The additional length allows the machine to accommodate nearly all the gundrilling applications a job shop will encounter.

The M75-48T has a gundrilling diameter range of 0.055″ to 0.750″ (1.40mm to 19.1mm). It features two gundrilling spindles with independent spindle control, allowing two different drilling cycles at the same time. The machine also uses counter-rotation of the workpiece to improve drilling performance.

The machine has cast iron boxways and hand-scraped spindle housings (versus linear guide ways and milled surfaces) for consistent vibration damping, extended tool life, and improved surface finish.
