Gun-Drilling

There are many applications for gun-drilling in the fabrication of large dies and machine-tools:

• Water-cooling system
• hydraulic-connections
• lubrication-lines
• pneumatic-connections
• in forged blocks of tool-steel
• in large welded structures
• in flat plates and base structures
• in aluminium-plates and bars

Gun-drilling is typical in the area of:

• diameter from 8 mm to 50 mm
• drilling depth from 2000 mm to 4000 mm
• tolerances are so tight, that several deep holes will meet straigth or at angles. So total depth can be doubled by drilling from both sides !

For large blocks of forged or rolled steel it is necessary to anneal and to homogenize the material before drilling. With our large kilns we can heattreat in-house, and thus realize perfect deep holes with short delivery time and no additional transports.
