Kondisi: bekas, Tahun pembuatan: 1990, Core drilling diameter – max. 6 mm Drilling depth 350 mm Swing diameter mm Total power requirement 15 kW Ledpfxjt Hw A To Aahehr Machine weight approx. 3500 kg Space requirement approx. 5000 x 1200 x 2200 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 drill steady 500 mm Installation length between tailstock and fixed drill steady 450 mm Quill travel max. approx. 450 mm Tailstock sleeve stroke 40 mm Tailstock adjustment on table 450 mm Table size approx. 400 x 680 mm Continuous feed rate 20 – 850 mm/min (!) Rapid traverse approx. 7,000 mm/min Infinitely variable spindle speeds 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 requirement 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 performs the drilling feed and rapid retraction. This allows for significantly higher feed and rapid traverse speeds, and the travel distances of the drilling tool are considerably shorter. This enables much higher economical efficiency in small-diameter drilling operations. 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, spindle speed max. 360 rpm, traversable approx. 450 mm longitudinally on the table. Large coolant installation mounted on the machine with high-pressure pump approx. 100 bar and 5.5 kW output, tank volume approx. 250 litres with circulation pump, and with band filter unit 10 my (fleece), coarse chip collector. Control panel with KM pressure indicator and effective current display as well as digital display for spindle speed, feed rate, and coolant temperature, and potentiometer for infinitely variable spindle speed and feed rate settings. Drilling depth/travel/return stroke are entered electronically via keyboard panel. Various warning and malfunction indicator lamps, process control managed by a SIEMENS S 5-100 U controller. Fully soundproofed machine enclosure with sliding doors for quick changing of workpieces and tools (collet chuck mounting). Various small-diameter drilling tools included.
