SCHIESS RF 30 gear hobbing machine

The SCHIESS RF 30 gear hobbing machine is a specialist machine for machining large gear wheels. The machine is designed for machining of gears by processing individual pitches of a gear wheel. The milling machine processes a workpiece with diameter from 60 mm to 3500 mm and a weight of up to 25 t. The spindle of the milling machine rotates at a speed from 6 to 69 rpm. The SCHIESS RF 30 machine is designed for milling with: – cylindrical milling cutters in steel / cast iron up to module: 24/30 – disc milling cutters in steel / cast iron up to module: 33/42 – end mills in steel / cast iron up to module: 33/42 50/65 Technical data of the SCHIESS RF 30 milling machine largest diameter of the milled workpiece: 3500 mm largest diameter of the milled workpiece in the circumferential method and with tooth pitch up to 45 3000 mm smallest diameter of the milled part: 60 mm largest vertical adjustment of the milling machine slide: 2000 mm maximum load of the chuck disc: 25 t external diameter of the clamping table of the chucking disc: 1980 mm external diameter of the chucking disc 2200 mm diameter of indexable worm wheel: approx. 2000 mm average pitch worm stroke: 8.Pi grip disc opening: 500 mm bore depth: approx. 1000 mm largest diameter of hobbing cutter: 320 mm largest diameter of circular milling cutter: 360 mm largest tooth pitch (inclination to wheel axis): 45 degrees diameter of the milling spindle in the front bearings: 150 mm rotation of the milling spindle: 6-69 rpm. rotation of main drive motor: 690-2250 rpm. power of main engine: 18 kW feed of the milling slide per rotation of the chuck disc, for circumferential milling: 0,16-8 advance of the milling sieve per rotation of the milling disc, for single pitch milling: -0,16-8 Feed rate of the milling ram, for worm gear milling, per rotation of the chuck disc: 0,08-4 rotation of the chuck disc when setting the machine to work: 0,7-1,8 rpm motor rotation for quick changeover: 700-2100 rpm. motor power for quick changeover: 8 kW quick changeover of the milling machine slide: 150-450 mm/min. rapid traverse rack: 150-400 mm/min.
