Liebherr will exhibit their LCS 1200 gear grinding machine at IMTS. LCS 1200 combines both generating and profile grinding into one machine. It is able to handle workpieces up to a diameter of 1200 millimeters. Gears up to module 12 can be economically processed with the generating grinding method. The machine has the capacity to produce noise-minimized gears in a two-flank grinding process exactly to a specified twist design. With profile grinding, gears up to module 22 or a profile height up to 50 millimeters can be ground. Tools with either electroplated cBN or dressable tools with corundum, sinter corundum, or cBN basis can be used for both grinding technologies. The high productivity machine can be supported by machine-integrated automation, also designed and built by Liebherr. For the generating-grinding method, the maximum outside diameter of 320 millimeters on a grinding worm and the minimum usable diameter (which depends on the gear data), built in combination with the tool length of 230 millimeters, offers the longest tool life in this machine type class on the market.
