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 straight 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 heat-treat in-house, and thus realize perfect deep holes with short delivery time and no additional transports.
