Drilling Machines

TBTA-3A-6 Deep-Hole Drilling Machine

The TBTA-3A-6 has 6 inches (152 mm) of BTA drilling capacity and 48 inches (1,219 mm) of drilling depth. The work table moves horizontally back and forth to provide the X-axis travel, and the drill slide moves vertically on a column to provide Y-axis travel. The spindle motor is available with up to 75 HP. The high-pressure coolant system is rated at 200 gallons/minute of coolant flow and 1,500 psi of coolant pressure.

Small-Caliber Gun Barrel Processing Cell

A cell is typically composed of three machines. First, Precihole’s four-spindle gun drilling machine permits deep drilling of four barrels simultaneously. An open machine configuration facilitates robot access, minimizing operator involvement and supporting 24/7 operation. Depending on individual model configuration, the machine can drill IDs from 0.04" to 1.57" and barrel stock from 0.4" - 4.0" OD.

D3120 Indexable Insert Drill

Available in diameter sizes ranging from 0.562-1.375 in. and 16-42 mm with 2, 3, 4 x Dc, the new drill delivers maximum process reliability with simple and efficient chip removal, two coolant channels and polished flutes. Superior protection against friction is provided by the D3120 hardened and polished surfaces. This combination of surface hardness and improved coolant flow results in reduced wear on the drill surface.
