EVO 400
EVO 400
The EVO 400 CNC Hobbing Machine is designed for precision gear hobbing with a maximum nominal module of 8 mm and a maximum workpiece diameter of 400 mm. It supports a hobbing width of up to 600 mm and a swing diameter of 570 mm. The machine features a hob arbor taper of SK45 hydraulic and a spindle speed range of 100 to 1200 rpm. The worktable has a rotational speed of 0 to 120 rpm and includes a diameter through hole of 375/160 H6 mm.
The machine is equipped with Siemens SINUMERIK ONE CNC, offering a simple and intuitive programming interface. It includes an asymmetric hob head, hollow torque motors on both the hob spindle and worktable spindle axes, and an optional two-position ring loader with an anti-collision device. Additional features include an NC tailstock, automatic thermal drift compensation, and a high energy efficiency chiller.
The tailstock and axes offer rapid traverse speeds of 10,000 mm/min (X axis), 6,000 mm/min (Z axis), and 3,000 mm/min (Y axis). The machine's compact layout is CE certified, ensuring compliance with safety standards.
The EVO 400 CNC is the first digital native CNC capable of creating a digital twin for improved business efficiency. It allows for simulation of part programming and machine operation on a PC, reducing design phase time and time to market. The machine supports continuous production monitoring and offline analysis.
The machine includes a high-efficiency motor and an HFK compact hydraulic power unit with a frequency converter, optimizing energy consumption. The high-efficiency chiller complies with Ecodesign regulations and features oversized heat exchangers and high-efficiency fans.
The machine can create hobbing toothing with large diameters, previously impossible on other machines. It supports designing clamping fixtures with larger diameters without collision risks, enhancing process rigidity. The asymmetric hob head offers high rigidity and precision, with a high torque motor and Heidenhain absolute ring encoder.
