Kay Engineering's Gundrilling Machine Performs Range of Operations
Kay Engineering’s DeHoff 20144 is used to perform gundrilling, pull boring, roller burnishing and thread tapping.
Kays Engineering’s DeHoff 20144 is a custom gundrilling machine designed and manufactured in Marshall, Missouri. According to the company, the DeHoff 20144 is used to make components for the world’s largest nuclear fusion reactor, the ITER Tokamak. Fusion reactors use extreme heat to fuse atoms together and create massive amounts of energy, while also not generating radioactive waste, CO2 nor greenhouse gas emissions.
The DeHoff 20144 is used to perform gundrilling, pull boring, roller burnishing and thread tapping on aluminum microwave guides. The microwave guides are long tubes used to heat the plasma fluid inside the Tokamak vacuum chamber to 150-million-degrees Celsius — the temperature needed for nuclear fusion.
The DeHoff 20144 has a gundrilling diameter capacity of 2" (50.8 mm) and a maximum drilling depth of 144" (3,658 mm). It features custom workpiece fixturing and tooling to perform the gundrilling, pull boring, roller burnishing and thread tapping operations all on a single machine.
Both the 420 (410) and 465 (464) digital boring heads come equipped with a 3ETech docking port for easy digital diameter adjustments.
The TinyMiniTurn line features a full range of solid carbide mini boring bars that enables machining from as small as 0.6 mm (.024″) diameters.
The L-703B Self-Centering Bore Alignment System works with Hamar Laser’s patented, self-centering targets that require only one measurement per bore.
