Long hole drilling precision metal processing by gundrill
Precision long hole drilling is a drilling process using a gundrill. As its name suggests, a gundrill was a type of drill for drilling the barrel of a gun. Nowadays, such crafting techniques and the facility thereof for drilling long straight holes are applied to various types of machinery parts.
Long hole drilling is performed by rotating each of the tool and the circular cylindrical object relatively to one other to avoid slide and bend of the hole. In the case of long hole drilling (φ0.1 diameter and 1,000mm lengths), the difference between the size of entrance and exit of a hole is within 1 mm error. However, the error difference depends on the outside diameter, the material and straightness thereof
We can perform long hole drilling within a range of φ4~32 and in range of less than φ4 by using several types of machinery and equipments.
Actual Performance:
Case 1 – φ1.0 mm diameter and 110 mm lengths
Case 2 - φ0.8 mm diameter and 90 mm lengths
We are proud of performing long hole drilling of not only for circular cylindrical objects but also for cubical objects. We also perform multiple holes drilling on end faces with high positional accuracy using NC machines. This multiple long holes drilling on end faces is available within a square range from 500mm wide to 240mm long for almost any size of objects.
EXAMPLES OF MACHINERY PARTS
Hinges for aircraft
(Indispensable technology for straight long hole drilling for tough-grinding material)
Drilling hole for cooling in large food-related machinery
(Difficult positioning for different material objects)
