Precision leveling wedge LA series

for machine tools

Farrat Levalators improve large, precision and long bed machinery performance by increasing alignment accuracy, rigidity and stability as the most accurate method of precision alignment. Improving large, precision and long bed machinery performance Farrat Levalators improve large, precision and long bed machinery performance by increasing alignment accuracy, rigidity and stability as the most accurate method of precision alignment. Large machines generally need good foundations both to reinforce the machine bed and to reduce vibration by mass damping. Farrat Levalators are the vital connection between machine and foundation enabling machine and foundation to become one unit. A machine on weak supports may as well not have a foundation. They can be fully grouted in, thus achieving a virtually built-in or encastré support which considerably increases the stiffness of the machine base and creates a complete machine foundation integration. Farrat Levalators overcome all the deficiencies of jackscrew support. Jackscrews are generally inadequate for large machine support as they are only virtually pivot supports and are therefore not stiff enough either horizontally or vertically. They distort under excessive loads thus limiting hold down bolt tension and create localised stressing in both machine bed and support plate. Our Levalators consist of a high grade cast iron basebox machined on the inside to support the screw driven fully machined lower wedge (high grade cast iron) which in turn elevates the fully machined steel top wedge.
