Chamfering Machine Offers Fast Setup, Processing Speed

Liebherr offers its LCD 300 ChamferCut, a stand-alone chamfering machine using the company’s ChamferCut method designed for repeat accuracy and long tool life. The ChamferCut method is said to offer a number of advantages for gear deburring, including high speed; no reduction in hob length; independent selection of hob and ChamferCut geometries; smaller and more broadly applicable tool diameters; and long tool service life in dry machining.

The machine enables geometrical optimization of gear clamping for chamfering purposes and provides maximum rigidity for machining. These features plus fast setup enable it to perform the same finishing work on gears as roughly two to three hobbing machines, the company claims. New software for the user interface is based on Fette ChamferCut tool settings sheets, and the operator can enter and correct ChamferCut process settings via the CNC axes. The machine is loaded automatically in line with the ring-loader principle, although the use of robots or gantries is also a possible alternative. This makes its incorporation into an automation process flexible.
