This large press had some really tight parameters to achieve, 100kN push force, 4m long, and squareness and runout of microns!
Precision Bosch linear roller rails were used, calculated not to move during the pressing forces. Planetary Roller Screw was used to provide the force whilst retaining the speed needed to move the carriage.
Coupled with a load cell for force measurement, and a linear measurement system capable of 0.3 micron accuracy, this machine was seriously accurate.
All controlled with Labview, and integrated into the customer’s product control system.
