The Elma all-electric machine series from Negri Bossi USA, Newark, Del., has been renamed and upgraded for faster injection, more precise and repeatable movements, and reduced maintenance. In particular, direct-drive clamping has been extended to larger models. The new Canbel VE line will make its worldwide debut at the upcoming NPE show in Chicago in June. The series includes 11 models from 77 to 935 tons. Each model has four Siemens servo motors, one each for the clamp and ejection, while the injection unit has two servo motors arranged one behind the other and coupled directly to the screw. Negri Bossi now also uses direct drive on the toggle clamp of machines from 300 tons on up (previously it was used only on smaller models). Direct drive provides higher clamp speeds than before on the larger presses. The servo motors have an "energy return system," which recaptures energy used while braking (decelerating) the motor. Negri Bossi says this provides a 2.3% energy return. The Canbel VE series is reportedly unique in having separate lubrication systems for the ballscrew and toggle, which allows using different lubricants appropriate to each function. Controls have been upgraded to allow users to create custom-configured screens. The Canbel line uses the same base frame as Negri Bossi's Canbio hydraulic machines, which reduces the overall cost of the new press line. It also allows customers to combine features of the Canbio and Canbel presses to yield hybrid designs.
