Vertical gear shaping machine OHA50 CNC5

OHA 50 CNC 5 – vertical gear shaping machine with SINUMERIK 840 D control system ensuring control of five axis, and with digital servo-drives of controlled axis is very powerful universal shaping machine intended for shaping of inner and outer gearing of face gears with straight and helical teeth. Besides control of individual axis the system ensures control of all functions of the machine, course of automatic working cycle and fault and operation diagnostics.

The machine may shape also various curved disks, geared segments, and with special accessory also racks to length of 1000 mm. Up to 20 cuts may be selected for each shaping. Optimal cutting conditions may be selected for each cutting. Other machine versions enable the enlarged properties of the machine. Great working extent and applications determine this machine especially for piece and small lot production. The gear shaper OHA 50 CNC 5 with its conception and advantageous design fulfils the requirements of modern industry due to power, accuracy and machined surface quality.
