Ecogrind VX5 NEO


Ecogrind VX5 Neo is the flagship offering from the house of WIDMA Tool Grinding machines. The machine has high power and high torque is a directly driven grinding spindle that operates at the peak power of 38kW, with a maximum RPM of 9000 with oriented stop. The machine has an automatic wheel changer with five grinding wheel packs to enable the manufacturing of complex tools without breaks for unloading and reloading. Direct drives on the A and B axes ensure higher indexing accuracies, working at the maximum speed of 1200rpm and 50rpm. All the linear axes ball screws are directly coupled with AC servomotors, roller type guideways, and linear scales for all linear axes and move at the maximum traverse speed of 20m/min.

The machine comes with three-layer protection for ball screws and guideways that prevent operational breakdowns. The Ecogrind VX5 Neo is ideal for manufacturing tools from solid blank ranging in diameter from 3 to 25mm. Automation features such as automatic wheel pack measurement, robot loading/unloading for tools, and CNC traveling steady rest can opt for uninterrupted production of large batch size.

The machine comes with standard safety features such as an automatic fire extinguisher, pneumatic counterbalance for the vertical axis in addition to brake on the vertical servo motor, front door locking while auto cycle is on, and axes collision check through software. Ecogrind VX5 Neo is equipped with Num CNC and Numroto software – a globally preferred combination by tool makers.
