Gundrilling of Camshafts Improves Engine Efficiency



The DeHoff 1024C is a six spindle gundrilling machine used for high-volume production of automotive camshafts. The machine is designed to gundrill a hole down the centerline of the camshaft to reduce weight. This enables a Tier 1 automotive supplier to produce lighter camshafts in large volumes for use in new high-efficiency engines.

The 1024C has a gundrilling capacity of 1" (25.4 mm) and a slide travel of 24" (610 mm). It features six gundrilling spindles on a single machine base, and utilizes adjustable tailstocks and hydraulic workpiece clamping. The camshafts are automatically loaded and unloaded using a lift & carry material handling system.

The machine features steel box ways and hand-scraped mating components rather than linear guide ways and milled surfaces. "This results in superior vibration damping, extended tool life and improved surface finish," said a Kays Engineering spokesperson.

DeHoff gundrilling machines are designed and manufactured by Kays Engineering in its Marshall, MO, facility.
