Mahr M2

Stav: použitý, Rok výroby: 1990, Maximum core drilling diameter: 6 mm Drilling depth: 350 mm Swing diameter: mm Total power requirement: 15 kW Machine weight approx.: 3,500 kg Space requirements approx.: 5,000 x 1,200 x 2,200 mm TECHNICAL DATA: Drilling diameter - solid drilling approx.: 1 - 6 mm Drilling diameter - boring approx.: 10 mm Drilling depth: 350 mm Centre height above table: 170 mm Installation length between quill head and fixed drilling steady: 500 mm Installation length between tailstock and fixed drilling steady: 450 mm Stroke of the drilling quill max. approx.: 450 mm Fedpfjt Hw A Tox Acxjpd Stroke of the tailstock clamping quill: 40 mm Tailstock traverse on the table: 450 mm Table size approx.: 400 x 680 mm Drilling feed, stepless: 20 - 850 mm/min (!) Rapid traverse approx.: 7,000 mm/min Spindle speeds, stepless: 5,000 - 12,000 - 24,000 rpm (!) Work spindle drive: approx. 4 kW * Total drive approx.: 15 kW - 380 V - 50 Hz Weight: 3,500 kg * Space requirements approx.: 5,000 x 1,200 x 2,200 mm Accessories / Special equipment: The high-frequency drilling spindle is housed in a rectangular quill, which carries out the drilling feed and rapid return. This allows for significantly higher feed and rapid traverse speeds, and the travel paths of the drilling tool are considerably shorter. This ensures much more economical operation in the small drilling diameter range. The HF spindle is a GMN spindle type TSSV 120 S, oil-cooled, controlled via REFU. Hydraulic workpiece clamping tailstock, motor-driven, approx. 0.8 kW, stroke approx. 40 mm, quill speed max. 360 rpm, travels approx. 450 mm longitudinally on the table. Large drilling oil unit mounted to the machine with high-pressure pump approx. 100 bar and 5.5 kW output, tank volume approx. 250 litres with circulation pump, and band filter unit 10 µm (fleece), coarse chip collection container. Control panel with km-pressure indicator and effective current indicator as well as digital display of spindle speed, feed rate, and coolant temperature, plus potentiometers for stepless input of speed and feed rates. Drilling depth/working stroke/return are entered electronically via keypad. Includes various fault indicator lamps, sequence control by SIEMENS S5-100U controller. Complete noise-insulated enclosure of the machine with sliding doors for quick changeover of workpieces and tools (collet chuck mounting). Various small-diameter drilling tools included.
