In 2019 SerWeMa successfully delivered a second large milling head AWK M40U for gear cutting machines in the range of Ø4.000 mm – Ø14.500 mm and module range up to 50 mm. A recent significant increase in demand for large gear cutting machines and the resulting orders inevitably leads to an increased demand for high-performance milling heads. Up to now – especially in the large machine sector – all parts have been manufactured completely new, i.e. from the new housing casting to the last gear wheel. Current simultaneous orders in the range of up to Ø4.000 mm each in India, Slovenia and China, up to Ø8.000 mm in India, up to Ø14.000 mm in Australia and up to Ø14.500 mm in Russia have given us the opportunity to find an alternative solution to the costly new production.

The great challenge was to develop a modern milling head that would meet the constantly growing requirements in terms of set-up time, machining time, rigidity and, last but not least, the demands of ever more powerful tools. SerWeMa has once again implemented its own core competence of modernization in this key component group. From the “old” conventional milling head, a motor milling head with an impressive 74 kW drive power and a powerful 10.000 Nm torque at the milling spindle was developed.
Further technical data can be provided as follows:
Max. Cutter diameter: 400mm
Max. Cutter length: 500mm
Max. Cutter adjustment (shifting): 600mm
Max. millable module: 40mm (gear hobbing)
50mm (single part / form milling)
Max. Cutter speed: 125 rpm (higher on request)
The result is a milling head that can be manufactured or made available at short notice, but is at the same time powerful and reliable, and can easily compete with comparable new products!
We look forward to hearing from you. We can also offer similar reconstructions and modernizations for many other machine types (SCHIESS, KOLOMNA, LIEBHERR, PFAUTER, etc.).
