the benchmark for flexible orbital grinding
In addition, the Landis LT2e delivers improved cycle times and maximized production levels with industry leading spindle power. Integral drive and hydrostatic bearings ensure the highest quality roundness.
Meanwhile, ergonomic loading and the ability to simultaneously grind with wheels spaced as close as 20 mm, ensures cycle time is kept as low as possible and parasitic time is reduced to a minimum.
Machine highlights
This machine continues to set the benchmark for precision and performance in orbital grinding with additional features that include:
- CBN grinding wheels
- Fully hydrostatic spindles and way systems
- Linear motors for linear axes
- Reliable, high-accuracy machining of complex components
- High quality finish
