HELTOS SIRIUS VS 25-290 UPRIGHT DRILL PRESSES

Technical Description

The HELTOS SIRIUS VS 25-290 is a robust upright drill press designed for precision drilling, reaming, and threading in both single-part and series production. It features a 35.4-inch swing and a powerful 1.5 HP (1.1 kW) motor operating at 900 RPM, delivering a spindle speed range from 80 to 2,800 RPM with two selectable speed ranges via a frequency converter. The drill press accommodates a maximum drilling diameter of 1 inch in 600 MPa material with a drilling depth of 7.1 inches. It utilizes a Morse taper #3 spindle, offering a spindle reach of 10.4 inches and a maximum distance from spindle end to table of 35.4 inches, with the table height adjustable between 7.1 and 35.4 inches. The worktable measures 12.6 by 12.6 inches, equipped with three T-slots (0.55 inches wide, spaced 3.15 inches apart) for flexible clamping. The machine’s column diameter is 4.7 inches, with a vertical headstock movement of 6.7 inches and a vertical bracket movement with the table of 16.1 inches. The feed mechanism provides four steps with feeds ranging from 0.003 to 0.013 inches per revolution, enabling fine axial pressure up to 1,798 lbf on the spindle. The drill press includes a coolant system with a 20-liter tank and a 30 liters/min flow rate for efficient cooling during operation. The overall machine dimensions are 25.6 inches wide, 44.5 inches long, and 90.6 inches high, reflecting a robust and versatile design for heavy-duty drilling applications in demanding workshop environments.
