Gundrilling is a deep hole drilling process that uses a long thin cutting tool to produce holes in metal at high depth to diameter ratios.
Gun drill machine.
Gun drills are straight fluted drills which allow cutting fluid either compressed air or a suitable liquid to be injected through the drill s hollow body to the cutting face.
It permits high quality deep hole drilling.
Dependent on the requirements of the hole the machine conditions the batch size and the drilling depth gühring determines the most economically efficient tool option.
Gundrilling machines are capable of precision holes from 1 50 mm 0 04 2 00 in in diameter and can maintain accuracy in extreme depth to diameter ratios.
Gun drilling or deep hole drilling is a hole making machining process that generates holes that can be up to 200 times longer than the diameter of the hole.
Gun barrels are the obvious example.
Gun drilling is effective in diameters from 1 50 0 04 2 00 in.
