Weiss Spindeltechnologie motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of Weiss Spindeltechnologie motor spindles — a German manufacturer of high-precision motorized spindles, part of the Siemens/Innomotics group, whose spindles equip many machine-tool builders across all brands.
Weiss Spindeltechnologie, German motor spindle specialist since 1957
TLDR: Weiss Spindeltechnologie (Maroldsweisach, Germany, founded in 1957, a wholly owned subsidiary of Siemens since 2003, now part of Innomotics) is a recognised specialist in the development and manufacture of high-precision motor spindle units for turning, milling, grinding and robotic machining.
Founded in 1957 in Maroldsweisach, Bavaria, Weiss Spindeltechnologie has established itself as a leading player in the development and manufacture of high-precision motor spindles. Having become a wholly owned subsidiary of Siemens AG in 2003, and then part of Innomotics GmbH, the company designs a full range of spindles, standard or bespoke, for a wide variety of machine-tool builders. Unlike a builder of complete machines, Weiss supplies its motor spindles as a component, subsequently integrated by third-party manufacturers into their own machining centres, lathes or grinding machines — which is why it is not uncommon to find Weiss spindles on machines from very diverse brands (Blohm, Bridgeport, Chiron, Famup, Grob, Hermle, Huron, Liechti, among others).
A range of motor spindles covering turning, milling and grinding
TLDR: Weiss offers an extensive range of motor spindles — high-torque spindles for turning, powerful B-axis milling spindles for lathes, twin-wheel grinding spindles for machining with virtually zero axial expansion — as well as fully customised solutions for specific applications.
Weiss covers the full spectrum of machine-tool builders' motor spindle needs: high-torque spindles designed for turning applications, special spindles made to measure for demanding turning operations, powerful B-axis milling spindles for multitasking lathes, as well as grinding spindles fitted with two wheels for machining shafts with virtually zero axial expansion. The manufacturer also offers indexed electric spindles for turning and fully customised solutions, built to order according to the precise requirements of the end customer. Each spindle undergoes rigorous quality control, including verification of the electrical continuity of the rotors, insulation, impedance and breakdown resistance of the stators.
