TECMES, a Company of AUTOROTOR group, manufactures mechanical base assembly machines with radial arms, full production lines and special equipment as per customer's needs. One of the most important advantages of the radial arms system is that a single power source ( a motoreducer located inside the bench) drives all the main syncronized movements like: - rotation of piece-holder disk - arms simultaneous movement - turret lifting and lowering . Other significant pros are: - high production rate: up to 120/140 pieces/min. - easy access to the machines - low maintenance and running costs - low installed power: about 1.5 Kw - low price. The operating priciple of the machine is patented.
