Gun drilling is the machining of holes with a large diameter to depth ratio. Conventional drilling involves drilling holes slightly more than five times the diameter, while gun drilling can be as deep as 150 times the diameter of the hole. In any case, a hole with a depth equal to ten diameters must be processed using gun drilling methods and on specialized equipment. Deep hole machining is required in areas such as steel, nuclear power, aerospace, and oil and gas. Here, both the high quality of the holes and their dimensional and geometric accuracy are extremely important.
- Drilling high-strength steels
- Small diameter deep hole drilling
- Permanent control of the position of the drill
- High drilling precision
