Landis LT2HHe

heavy-duty
crankshaft grinder

With the ability to process crankpins and journals on crankshafts and other components up to 4.5m long, the Landis LT2HHe is the world’s largest capacity, fully-automatic twin wheelhead CBN grinding machine. It provides precision, flexibility and productivity, combined with high quality and efficiency.

heavy-duty crankshaft grinding for large applications

Designed to handle large components, the Landis LT2HHe includes all of the fundamentals you would expect from a Landis machine. Combining high flexibility and precision with reliability and throughput.

Workheads are servo-driven to improve accuracy by eliminating torsional windup and vibration. Belts, pulleys, gears and jack shafts are also eliminated, helping to reduce maintenance and downtime.

automatic loading & unloading

The precision performance continues with hydrostatic wheelhead and cross slides, wheel spindles and workheads, as well as automatic in-process gauging, centerline correction, and taper control and adjustment.

Loading and unloading is also automatic, ensuring parasitic time is at a minimum while reducing the health and safety risks to operators.

RELIABILITY - FLEXIBILITY - PRODUCTIVITY

The reliable performance of the Landis LT2HHe ensures grind cycles are handled with ease while eliminating scrap. Meanwhile, its flexible table tooling with servo-driven rack & pinion adjustment and twin wheelheads provide the adaptability to process a range of workpieces.

Some of the many cycle options available on the LT2HHE include:

  • Finish grinding of two workpiece features simultaneously
  • Finish grinding a main and crankpin journal diameter in combined operation
  • Finish grinding other concentric diameters and thrustwalls by various sequencing of the wheelheads

key machine features

Stable and secure in its heavy-duty cast iron bed, the Landis LT2HHe includes a range of features that ensure a precise, high-quality finish.

  • Wear-free hydrostatic x-axis slideways for maximum stiffness, repeatability and vibration dampening
  • Linear motors for ultra-responsive and exact positioning
  • The z-axis is also controlled by a linear motor on linear rails for precision contouring and dressing
