The new Gear Shaping Machine LS 180 F
The LS 180 F is suitable for cluster gears machining
Liebherr-Verzahntechnik GmbH has expanded its portfolio for small workpieces with the LS 180 F shaping machine. This small shaping machine is equipped with a movable cutter head slide to shape in different axial positions without having long set-up times.
"Shaping continues to be the gear manufacturing technology of choice for gears to be part of transmissions with minimum available space - one of them being cluster gears with limited cutter overrun, which can be machined in one clamping without additional set-up times," said a company spokesperson. "To date Liebherr could only offer larger machines for such flexible applications, since its smaller shaping machines did not feature the necessary movable cutter head slide. The new LS 180 F now enables Liebherr to provide the right size of machine with a lot of features for small workpieces too."
This redesign now enables the cutter head slide to be operated electronically, which cuts down on set-up times and delivers greater precision. The feature also enables workpieces with both internal and external gear teeth to be machined in the same clamping operation. In this version the shaping machine is equipped with a twin-track cam as standard. The LS 180 F continues to be available with a mechanical helical guide. The new version is also compatible with older versions, meaning that existing helical guides and removal cams can be used with the LS 180 F.
"One actual application is, for example, a component used to adjust aircraft landing flaps," said Dr. Andreas Mehr from the Grinding and Shaping Technology Development and Application team at Liebherr-Verzahntechnik GmbH. "Every component features three gears that have to be positioned accurately to each other. That is why it is absolutely necessary to machine the entire gear tooth machining procedure in one clamping. But there are also potential customers for the LS 180 F in pump manufacturing as well as in the motorbike and tractor industry."
Given its range of possible applications, this machine could be of interest for job shops. "This machine is versatile," said Andreas Mehr. "Given its high stroke rate of 1,500 double strokes per minute, this machine can produce particular small quantities very cost-effectively."
The LS 180 F enables Liebherr to combine the small footprint of the Platform 1 with applications that were previously only feasible using larger machines.
