Gear hobbing semiautomatic machine BCH-332 CNC2 (NC2)

main / production /

The Gear hobbing semiautomatic machine with upright axis of workpiece for treatment of spur and helical gears, sprockets, worm wheels with hobs by method of form-generating. Structural features: The semiautomatic machine has a configuration with upright axis of workpiece and with movable table. The hydraulic cylinder of blanks clamping is built into the tables spindle. The semiautomatic machine DCY-332 СNC 2 is equipped with the CNC system mod SINUMERIK 802D and with the SIEMENS drives. The semiautomatic machine DCY-332 NC 2 is equipped with the SIEMENS pro-grammable controller and drives. Adjustment of rotational speed of hob spindle as well as of values of axial and radial feeds is realized with frequency converters-powered servomotors (depending on version) steplessly. High static and dynamic rigidity due to rational shape of column and support car-riage guides as well as rigidity increase of main shape-creating units. To use full length of hob cutting edge its periodical travel along the axis (shifting) is provided. The semiautomatic machine has a centralized lubrication system. Maximal outer diameter of gear to be cut, mm 320 Maximal module to be treated, mm 6 Maximal helix angle of teeth to be cut, deg 45 Maximal width of face to be cut (of spur gear), mm 220 Diameters of table, mm 250 Distance between the tool axis and the table axis, mm 25...250 Maximal dimensions of hobs to be installed, mm    - diameter 160    - length 140 Maximal hob travel along the axis (shifting), mm 120 Range of numbers of hob revolutions, rpm 50...500 Range of upright feeds, mm/min 1...1000 Range of radial feeds Mm/min 1...750 Number of coordinates to be controlled 3 Number of coordinates to be controlled simultaneously 2 Power of primary motion drive, KW 5,5 Overall dimensions (length x width x height), mm 2560х1470х1915 Weight of the semiautomatic machine, kg 6500
