HELTOS V 20 B UPRIGHT DRILL PRESSES

Technical Description

The HELTOS V 20 B is an industrial upright drill press manufactured by the Czechoslovakian machine tools factory, designed for precision drilling applications across various materials. This robust machine features a 1.5 kW three-phase motor operating at 400V with a 1400 RPM input, delivering variable spindle speeds ranging from 71 to 2,800 RPM through 15 distinct speed steps achieved via a V-belt drive system with adjustable tension. The drill press accommodates a maximum drilling diameter of 20mm with a Morse #3 spindle taper and offers a drilling depth of 160mm, supported by a 250mm spindle reach. The machine's rigid cast iron column measures 110mm in diameter and provides 350mm of vertical headstock movement for enhanced workpiece accessibility. The horizontal clamping table measures 320 x 320mm and features three T-grooves (14mm width, 80mm spacing) for secure workholding, with adjustable positioning between 150-500mm from the spindle end. The feed system provides both manual and mechanical options with four selectable steps ranging from 0.08 to 0.32 mm/rev, while a geared rack mechanism controls vertical table and headstock movement. The machine incorporates a mechanical clutch and right-left reversible spindle capability, achieving a maximum axial spindle pressure of 4,000 N. An integrated coolant system supplies 30 L/min from a 20-liter capacity reservoir. Overall dimensions of 510 x 970 x 1,345mm (W x L x H) make this a substantial industrial-grade installation, suitable for job shops and manufacturing facilities requiring reliable, repeatable precision drilling.
