Kay’s Engineering’s DeHoff 518 cell is a gundrilling machine for high-volume production of scroll compressor driveshafts. The shaft requires a different diameter hole to be drilled in each end for lubrication of the scroll bearing. 

The gundrilling machine is comprised of nine gundrilling spindles used to drill the opposing holes. The larger diameter, shorter hole is produced first using three gundrilling spindles on a single machine base. The smaller diameter, deeper hole is produced next using six gundrilling spindles, two separate machine bases with three spindles each. 

The gundrilling machine has a 0.5” (12.7-mm) gundrilling capacity and an 18” (457-mm) slide travel. The machine features a cast-iron drill head base with hardened and ground steel box ways, plus hand-scraped and fitted saddle, gibs and straps versus linear guideways and milled surfaces.
