Gundrilling Machine’s Hand-Scraped Features Increase Accuracy

The DeHoff 1024C six-spindle gundrilling machine from Kays Engineering makes centerline holes in automotive camshafts such as those used in high-efficiency engines. The machine has a 1" (25.4-mm) drilling capacity and a 24" (610-mm) drilling depth. In addition to its six spindles, the 1024C features adjustable tailstocks and hydraulic workpiece clamping. Camshafts are automatically loaded using a lift-and-carry material handling system. Other features include a high-pressure coolant system, Beckhoff controls and a full machine enclosure.

A durable, heavy-duty design incorporates a cast iron drill head base with hardened and ground steel box ways, plus hand-scraped and fitted saddle, gibs and straps. This design provides high vibration damping, extended tool life, and improved hole accuracy and surface finish, according to the company.
