MTE spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of spindles and milling heads on MTE machines — fixed-bed and travelling-column CNC milling machines designed for machining large parts.
MTE, a specialist in bed-type and travelling-column milling machines
TLDR: MTE (MTE Deutschland GmbH, Montabaur-Heiligenroth, Germany) builds fixed-bed and travelling-column CNC milling machines, with high-power, high-torque spindles and a particular focus on service over the whole life of the machine.
MTE presents itself as a milling specialist and highlights innovation, quality and precision. Its catalogue includes fixed-bed CNC milling machines and travelling-column milling machines in several sizes: on the used market you find the BF, BT, RT and Kompakt Plus series, some installed for more than twenty years. The manufacturer offers maintenance and repair service from Montabaur.
High-power, high-torque mechanical spindles
TLDR: The MTE milling machines observed use ISO 50 (SK 50) gearbox spindles, with power ratings of 15 to 40 kW and swivelling milling heads.
Machine listings give a few orders of magnitude. A 2016 RT-3000 is listed with a 0 to 3,000 rpm spindle, 40 kW, 1,360 Nm of torque and an ISO 50 DIN 69871 AD taper. A 2000 Kompakt Plus is listed at 40 to 2,500 rpm, 15 kW, SK 50 taper. On the BF 3700, the manufacturer describes a 32/40 kW spindle motor and an automatic milling head swivelling 2.5° × 2.5° in two planes, with an oil-cooled three-speed gearbox. These values vary with model and year: we confirm them from your machine's nameplate.
On these heavy machining machines, an MTE spindle never works alone: the swivelling head and the gearbox are part of the same diagnosis. When a machine has been fitted with an MTE motor spindle or a retrofitted motorised spindle, we handle it the same way, with a run-in test in our workshop.
MTE spindles and heads covered (non-exhaustive list)
- Spindles of fixed-bed milling machines (BF, BT series)
- Spindles of travelling-column milling machines (RT series)
- Spindles of compact milling machines (Kompakt Plus series)
- Automatic swivelling milling heads
- Multi-speed, oil-cooled spindle gearboxes
Interfaces and specifications
The MTE spindles we repair are mainly ISO 50 / SK 50 taper (DIN 69871 AD), with power ratings between 15 and 40 kW and speeds of around 2,500 to 3,000 rpm on the examples found. Exact values depend on the model, to be confirmed on quotation.

Frequently asked questions
Do you repair the spindles of MTE fixed-bed and travelling-column milling machines?
Yes, we work on the spindles and milling heads of both machine families.
Do you work on swivelling milling heads?
Yes, we inspect the head, its swivel axes and its gearbox during diagnosis.
Do you repair older MTE machines with a Heidenhain TNC 410 control?
Yes, we work on machines whatever their year or CNC control.
What is the average turnaround for a complete overhaul?
Allow around 20 working days in our workshop, depending on the condition of the spindle and parts availability (bearings, seals, specific components).
