hole drilling

BHDT offers tube systems fabricated by deep hole drilling. With this high precision drilling operation tubes up to 21 m length with a drilling diameter from 20 to 200 mm can be fabricated.

With counter drilling even up to 300 mm inside diameter. The modern production equipment and the obtained know-how permit the treatment of different materials and allows very small fabrication tolerances. Due to high demands on quality and lifetime of high pressure components a smooth internal surface roughness is a mandatory requirement. BHDT achieves with the high precision honing machine an internal surface roughness better than Ra 0,1 µm on the high pressure components.
