Kays Engineering Inc.’s DeHoff G560-DR2 gun barrel drilling and reaming machine has a quick tooling changeover after the barrels are gundrilled that allows a pull-reaming operation to be performed using the same machine. 

Kays Engineering Inc.’s DeHoff G560-DR2 drilling and reaming machine performs both operations on gun barrels. After the barrels are gundrilled, a quick tooling changeover allows a pull-reaming operation to be performed using the same machine. The twin-spindle machine has a drilling capacity of 17 to 50 caliber and a slide travel of 60 inches (1524 mm), the company says.

According to the company, the G560-DR2 is part of a turnkey package of gun barrel manufacturing equipment offered by DeHoff, including machines for gundrilling, pull-reaming, button rifling, cut rifling, as well as tooling, heat treat ovens, and gaging equipment.

The drilling and reaming machine features a cast-iron drill head base with hardened and ground steel box ways, plus hand-scraped and fitted saddle, gibs, and straps. This results in vibration damping, extended tool life, and improved surface finish, the company says.
