Standard Equipment & Features
Integrated Milling and Hobbing Functions Planing Function Included Ø50 mm Arbor-Mounted Milling Spindle Counter Bearing for Maximum Rigidity Continuous Diagonal Hob Shift CNC-Controlled Machine Axes Automatic Steady Rest Height Positioning Long Rotor Machining Capability High Surface Finish Quality High Profile Accuracy
Machine Advantages
Milling and hobbing operations performed on one machine, eliminating secondary setups. Fully unattended machining of a complete rotor is possible. Capable of machining extremely long workpieces up to 8 meters. Easy conversion of existing machining programs to the LWN 300 PM coordinate system. All machine axes are CNC controlled for maximum precision. Automatic calculation and positioning of steady rests during machining. High-rigidity spindle with outboard support ensures excellent surface finish and long tool life. Continuous diagonal hob shift utilizes the entire hob face, distributing wear evenly. Complete rotor hobbing without frequent interruptions for insert changes or measurements. Designed specifically for high-precision machining of oil & gas rotors and other difficult-to-machine helical components.
