TBT spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of TBT spindles and motor spindles — the German manufacturer and world leader in deep hole drilling for more than 55 years (TBT Tiefbohrtechnik GmbH & Co.).
TBT Tiefbohrtechnik, world leader in deep hole drilling for more than 55 years
TLDR: TBT Tiefbohrtechnik GmbH & Co. (Dettingen/Erms, Germany, more than 55 years of experience) is the world leader in the deep hole drilling sector, offering the whole of deep hole drilling technology from a single source — from gun drilling through to bespoke special machine solutions.
TBT Tiefbohrtechnik has established itself as the world leader in the deep hole drilling sector, a reputation founded on its commitment, flexibility and capacity for innovation in delivering bespoke customer projects. The manufacturer offers the whole of deep hole drilling technology from a single source, from gun drilling through to the most specific configurations: drilling cylinder heads, engine blocks or moulds, as well as drilling machines with spindles arranged horizontally or vertically, in gantry or moving gantry configurations, for machining heat exchanger plates. TBT has developed automatic tool change solutions compatible with long 3/4 drills and long BTA drills. The manufacturer is also a member of the Nagel group (alongside Gehring, Kadia and O.erre.pi), which allows it to offer complementary processes such as deep bore honing or bearing grinding.
A range of very high speed spindles for precision deep hole drilling
TLDR: TBT deep hole drilling machines use spindles running from 3,000 to 27,000 rpm depending on the configuration, with spindle mountings from 10 to 60 mm in diameter, combined with high-pressure coolant systems reaching 150 bar to evacuate chips at depth.
On TBT deep hole drilling machines, such as the T30 series, the spindle can run across a very wide range from 3,000 to 27,000 rpm, with drive power of 3.7 kW in continuous duty (up to 5.5 kW at 50% duty) and spindle mountings covering diameters from 10 to 60 mm depending on the application. These spindles are combined with high-pressure coolant systems reaching 150 bar at a flow rate of 48 l/min, essential to evacuating chips through the tool at drilling depths that can exceed several metres. On gantry configurations dedicated to machining heat exchanger plates, several spindles can be arranged horizontally or vertically to process a large number of holes simultaneously.
