OFA 100 CNC 6 Gear hobbing machine with CNC control

OFA 100 CNC 6 – Vertical hobbing machine OFA 100 CNC 6 is intended for milling of face gears with straight and helical tooth, chain wheels, worm gears milled by radial and tangential method, gear wheels with longitudinal modification, spline shafts and other types of gears milled by hobbing-type machining.

Modern design with limiting of clearances of milling carriage and table enables milling of hardened gears and high-speed milling of non-hardened gears with hard-metal tools.
Machine is intended for serial and single-piece production. The machine is suitable both for the series or is single-piece production. Operation, setting up and maintenance of the machine are conceived to be performed simply, swiftly and with ease. Automatic work cycle of the machine along with possible basic application of a work application of a work magazine offers the facility of multi-machine attendance. In its basic version the machine is equipped with the SIEMENS Sinumerik 840 D control system and drives. There are six controlled machine axes.

Controlled axes OFA100CNC6

Axis X – feed of the main stand on a horizontal lines bed
Axis C – rotation of spindle clamping table (workpiece)
Axis Z – feed the body slides after the vertical lines main stand
Axis A – pivoted milling slide
Axis Y – tangential feed to the milling slides towards workpiece
Axis B – rotation motion spindle tool
