Series 450 - Drive power: 22 - 75 kW
For heavy parts and high throughput
Thanks to the extreme stability of the entire machine housing and the high moment of inertia of the solid, machined rotor, Hellweg Series 450 cutting mills enable the gentle yet powerful reduction of thick-walled molded parts, plates, sprues, pipes, profiles, etc.
A special rotor (BR version) allows for single-stage reduction of even the most massive starting blocks.
