6-Spindle Gundrilling Machine Produces Lighter Camshafts for Improved Automotive Efficiency

The DeHoff 1024C 6-Spindle Special is a custom-designed machine for gundrilling a centerline hole in automotive camshafts. It enables a Tier-1 automotive supplier to produce lighter camshafts in large volumes for use in new high-efficiency engines.

The 1024C has a 1-inch (25.4 mm) drilling capacity and a 24-inch (610 mm) drilling depth. It features six drilling spindles on a single machine base, and utilizes adjustable tailstocks and hydraulic workpiece clamping. The camshafts are automatically loaded using a lift-and-carry material handling system.

The machine features a durable, heavy-duty design that incorporates a cast iron drill head base with hardened and ground steel box ways, plus hand-scraped and fitted saddle, gibs, and straps (versus linear guide ways and milled surfaces). This results in superior vibration damping, extended tool life, and improved hole accuracy and surface finish. Standard elements are also included on the DeHoff 1024C, such as a high-pressure coolant system, Beckhoff controls, and a full machine enclosure.
