Turning Copper Commutators with the Know-how of LACH DIAMANT
Since the 60s, names like Bosch, Siemens and at that time AEG stand for the development and production of turning diamonds for turning copper commutators.
Worldwide the first presentation of polycrystalline diamond tools (PCD) at Hanover Trade Show in 1973 was at the same time the start of a new technology for machining non-ferrous metals – thereby also for the production of copper commutators. Up to that time, copper commutators were still machined with natural diamonds – with varying turning results – from 10 to a maximum of 120.000 pieces – the first use of this new cutting material by LACH DIAMANT, named “dreborid” PCD changed everything.
From now on, even Kautt & Bux, a manufacturer of raw commutators, could offer pre-turned copper commutators for the production of electric motors to its customers.
On the occasion of AMB 2018 in Stuttgart, LACH DIAMANT put together a special leaflet, featuring the entire PCD tool selection for maximum precision and tool life for the serial production of copper commutators, from now almost 50 years of experience. Showcased are PCD commutator turning tools for corner radius and peel turning.
A separate page is dedicated to prisms, or rather bearing shells, as surface during the turning of commutators in serial production.
Here too, the hardness of diamond – therefore PCD – proved its worth.
For all who cannot visit AMB or are unable to seek competent advice from LACH DIAMANT in hall 3 at stand 3E23, LACH DIAMANT put together a clearly laid out information package for an initial contact – please simply send your request to email@example.com.
