IMT GmbH spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of IMT GmbH spindles and motor spindles — the German manufacturer from Gießen founded in 1998, a specialist in high-frequency motor spindles reaching up to 100,000 rpm.
IMT GmbH, a German high-frequency motor spindle specialist since 1998
TLDR: IMT GmbH, a family business based in Gießen in Hesse, Germany, has developed bespoke spindle solutions for many sectors since 1998. The range covers milling motor spindles, grinding motor spindles (Grind series), solutions dedicated to printed circuit board drilling (PC Board), spindles for robotic applications and spindles for tooling and moulds.
IMT GmbH, a modern family business based in the heart of Hesse in Gießen, has developed bespoke spindle solutions for a variety of application sectors since its foundation in 1998. The product portfolio covers powerful, state-of-the-art spindles together with the accessories needed for production, with strict quality control and thorough testing across all products, all manufactured in Germany and certified to ISO 9001:2015.
The modular design of IMT spindles allows almost every spindle to be adapted to individual customer requirements and needs, with recognised expertise in bespoke solutions alongside a broad range of standard products. Applications cover automotive manufacturing, medical and dental technology, optics and signage technology, with spindles deployed in tool and mould making as well as in general mechanical engineering and specialised production lines. IMT also offers its own repair service: we work as an independent workshop, with no exclusivity, for manufacturers who want an objective diagnosis, a controlled turnaround from France or Switzerland, or coverage across a multi-brand fleet.
A range of modular IMT motor spindles, up to 100,000 rpm
TLDR: The IMT Classic series offers motor spindles in various models with rotation speeds up to 100,000 rpm, diameters from 16 to 140 mm and power ratings from 0.04 to 20 kW, complemented by the Grind series for high-precision grinding and a proprietary IMT4.0 sensor for bearing condition monitoring.
The IMT Classic series, a proven technology for cost-conscious use, offers motor spindles in various models with rotation speeds up to 100,000 rpm, diameters from 16 to 140 mm and power ratings from 0.04 to 20 kW — a span covering micro-machining as well as more substantial milling applications. The Grind series, intended for high-precision grinding applications, combines high bearing rigidity with excellent concentricity, with an intelligent Touch-Sense function providing dressing process monitoring.
The PC Board solutions, developed specifically for printed circuit board machining and protected by patent, offer quick and simple integration into the machine system. For robotic applications, IMT offers special solutions with interfaces giving robots an additional degree of freedom. The IMT4.0 sensor, developed specifically for bearing condition detection, stands out for its compact design, with a high-precision vibration sensor easily fitted to spindles already prepared for it, for integrated predictive maintenance. IMT also pairs its spindles with dedicated frequency converters (SD2S and SD2T types), whose power levels are specifically matched to each spindle series — a point to specify at quotation stage, since the spindle and its drive form a single assembly.
