For a diameter-length-ratio from 15xD one generally refers to gun drilling. Gun drills are for example applied for the machining of camshafts, crankshafts, drive shafts, injectors, drill pipes for oil production, in the medical and the food industry. Dependent on the requirements of the hole, the machine conditions, the batch size and the drilling depth Guhring determines the most economically efficient tool option.
With spiral deep hole drills type RT 100 T available as part of an extended ex-stock programme for the drilling depths 15xD, 20xD, 25xD, 30xD and 40xD, the user benefits from maximum feed rates and cutting speeds and therefore benefits from a significant reduction in manufacturing times. Guhring achieves these advantages thanks to the following features:
Die spiralisierten Tieflochbohrer verfügen über eine auf die besonderen Anforderungen speziell angepasste Nutgeometrie für einen optimalen Spantransport aus tiefen Bohrungen.
Drilling depths up to 20xD without pecking cycles
Optimal wear resistance and excellent cutting conditions with deep holes thanks to the newly developed point geometry with optimised S web thinning.
A specially developed parabolic flute form with optimised surface finish quality ensures optimal chip formation and chip evacuation.
High surface finish quality
Thanks to the bright flute with high surface finish quality the chips are optimally evacuated.
