ChamferCut solutions
The new stand-alone solution LD 180 C offers new opportunities for introducing
the method in existing production lines.
Clean-edge gear teeth prevent damage during workpiece
transport, hardness cracks, and gear wear. They also
facilitate the assembly process and improve the tool life.
Chamfering using ChamferCut delivers high-quality edges
with reproductive accuracy, and is more cost-effective than
press deburring and chamfering with tapered end mills. It
is thus no wonder that chamfering is so popular among car
and commercial vehicle manufacturers as well as in gear and
engine manufacturing. Advantages of the method
Perfect chamfers for existing production • ChamferCut tools can easily and cost-effectively be re-
sharpened approx. 20 times
The version with workpiece diameter up to 180 millimetres is
designed for the automotive area. Machines with a diameter
up to 300 millimetres are generally more suitable for contract
gear manufacturers and the truck sector.
As the installation area is restricted in existing lines, the
machine and control cabinet can be positioned separately as
an option. The machine can also be operated from the right
or left.
The loading can be effected by belts, robot cells or other
automation solutions. Similar to all Liebherr solutions for the
ChamferCut method, the LD 180 C also works with maximum
productivity in order to guarantee very short cycle times. It
can machine small to medium workpieces with a diameter up
to 180 millimetres and length of 200 millimetres. Although
extremely precise chamfers are created with the ChamferCut
method in comparison to other deburring methods, the
lowest tool costs are still incurred, which shortens the
amortization period considerably.
The LD 180 C and LD 300 C handle both wet and dry
machining, and have a high tool life with both machining
types. The machines have simple and intuitive controls,
which can be easily programmed with the user prompts.
