Deep hole drilling is done with special gun drills. Gun drills are straight fluted drills which allow oil to be injected through the drill’s hollow body to the cutting face.
The high pressure oil provides lubrication and cooling to the cutting edges and removes the swarf from the hole. Tolerances of drilling depends on the material being drilled and the accuracy of the deep hole drililng machine. Longer aspect ratios can be drilled with demanding tolerances. Depth-to-diameter ratio of 400:1 is possible.
Machinefabriek Tuin is equiped with 2 BTA machines and several ELB machines, all purpose-built gun drilling machines, to achieve highest productivity and process reliability.
A central oil management system assures best oil conditions, both on cleanness and temperature, which is a must for demanding products.
Common industries include energy, oil and gas exploration, Hydraulics, Automotive and plastic injection molds.
Deep hole drilling is a solution within demanding industries for integrated cooling systems, integrated electrics-and data communication wiring, integrated pneumatics and hydraulics.
