Company description
Sub-contract deep-hole drilling
Drill diameter 1 - 100 mm (solid drilling).
Drill depth up to 2000 mm (78 3/4 inches) from one side and up to 4000 mm (157 1/2 inches) from both sides.
centrical and eccentrical (asymmetric) drillings, if desired as well in oblique planes.
In any free cutting material up to an hardness of about 43 HRC respectively an tensile strengh of about 1300N/mm².
Workpieces up to a weight of 5.5 tons can be transported by our forklifts and gantry cranes.
On our depp-hole drilling centres we can provide additional work besides deep-hole drilling such as tapping,
reaming and 2.5D milling operations.
