Landis LT3e

large crankshaft
grinder

With part length capacity ranging from 4,500mm up to 8,500mm and beyond, the Landis LT3e is the ideal solution for large crankshaft grinding. Flexible, precise and productive, this is the state-of-the-art solution for your large crankshaft grinding needs.

Accurate, flexible and reliable grinding for large components

It’s not just the size of the Landis LT3e that’s impressive. It is also packed with the latest technological developments and features to ensure the highest quality and productivity, including:

  • CNC hydrostatic wheelhead and workhead bearings
  • Concentric and orbital capabilitiy
  • Up to 40 brushless servo axes
  • Hydrostatic wheel and crankhead spindles with integral spindle drives
  • Electronically synchronised crankheads
  • In-process gauging
  • Linear motors on infeed and traverse
  • Linear motor infeed and cross traverse on dresser

    Robust & Reliable

    In addition, the Landis LT3e can grind pins and journals up to 350mm in diameter, throw up to 250mm and swing up to 850mm. This is all possible while maintaining stability and performance at weights up to 8,500kg.

    In fact, geometric accuracy of the shaft is increased by grinding the crankshaft main bearings on axis, while orbitally grinding crank pins. All without having to remove the shaft from the machine.

    Low maintenance and minimized downtime

    With its long-lasting hydrostatic spindles and bearings, the Landis LT3e is a durable machine with low maintenance requirements. Downtime is minimized, which keeps production running efficiently, further saving you time and money. In addition, the health and safety risks associated with operator interaction are reduced.
