EcoGrind SX5 LiMo

HIGH TECH MACHINES FOR MICRO TOOLS

WIDMA’s Ecogrind SX5 LiMo is a specially designed machine for manufacturing micro tools, ranging from 0.5 to 12mm diameter. It features a high axial force linear motor for all axes to produce near-zero vibrations as required for such precision machining. It comes with a three-wheel pack automatic wheel changer (AWC) that can hold up to nine grinding wheels and helps produce complex micro tools in a single setup.

The machine operates at a peak power of 11kW. It has direct drives for both A-axis and B-axis to ensure higher indexing accuracy. The specially designed top clamp and steady rest ensure rigid support and clamping of the tool. The machine base is rigid enough to dampen the vibrations emanating from the cutting forces. To ensure the safety of the machine and machine operator, 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, axes collision check through software. Robot loading/unloading of tools helps running of the machine uninterruptedly for long working hours. Num CNC and Numroto software help to produce tools with tighter dimensional tolerance.
