The LT3 Large Orbital Crankshaft Grinding Machine is the latest innovation from Cinetic Landis Ltd. Designed to grind large crankshafts, the LT3 gathers state-of-the-art technological developments, providing outstanding features.
The machine grinds the crankshaft main bearings on axis and orbitally grinds the crank pins without having to remove the shaft from the machine, so increasing the accuracy of the geometry of the shaft. In addition, the machine is capable of grinding crankshaft end diameters, faces or tapers.
The design of the machine includes new FEA methods to develop unique bed and foundation design. The existing 6400 CNC machine control system was enhanced to allow the simultaneous application of up to 40 servo axes. New methods of supporting and locating the crankshaft together with unique grinding processes allowed finished part roundness results of less than 0,002mm on a 300mm diameter main bearing or crank pin. Both soft and hardened steel cranks have been ground. Hardened steel cranks include sidewalls & fillet radii.
