HOBBING MACHINE TYPE ZFWZ 8000x40

Transcription

1 Inventory number 416/635 Year of production 1973 Serial number 7160 HOBBING MACHINE TYPE ZFWZ 8000x40 Application The machine is provided for milling cylindrical, helical and helix cogwheels. The tooth strip can be made by hobbing method using a hobbing cutter. Worm gear is milled using tangential technique by conical hobbing cutter or using in-feed hobbing by cylindrical cutter. There is an option to indent herringbone and internal teeth Herringbone and internal tooth demand additional device, which is appointed to our machine tool. The machine tool is also used to drilling and boring hobbing holes.
