SycoTec spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of SycoTec spindles and motor spindles — SycoTec GmbH & Co. KG, the German manufacturer from Leutkirch, a recognised reference in high-speed precision motor spindles.
SycoTec, German reference in high-speed precision motor spindles
TLDR: SycoTec GmbH & Co. KG (Leutkirch, Germany) is a recognised manufacturer of high-speed, high-precision motor spindles, with compact models that have enjoyed particular success in bar turning, micro-engineering and the Swiss watchmaking industry.
SycoTec motor spindles, manufactured in Leutkirch, Germany, have established themselves as a reference in high-speed precision machining. The small type 4015 dc model, with a housing diameter of 25.4 mm, a power rating of 300 watts and running at up to 80,000 rpm, has enjoyed particular success with more than 500 units sold in France in bar turning and micro-engineering — the Swiss watchmaking industry having responded favourably to fitting this spindle on various machining centres. SycoTec today covers a wide range of applications (milling, drilling, engraving, grinding) with ranges extending from compact engraving spindles to automatic direct-grip tool change systems for industrial machining.
A range of hybrid bearing motor spindles, up to 100,000 rpm
TLDR: SycoTec motor spindles cover a wide speed range, from 5,000 to 80,000 rpm on standard models and up to 100,000 rpm on certain brushless (BLDC) motor configurations, with hybrid or steel bearings with lifetime lubrication and dynamic runout below 1.5 microns.
SycoTec motor spindles, such as the 4025 model, use a bearing system made up of two hybrid bearings and one steel bearing, with lifetime lubrication, guaranteeing dynamic runout of less than or equal to 1.5 microns for a collet clamping range of 0.3 to 4.0 mm. Three-phase asynchronous motor models cover speeds from 2,500 to 60,000 rpm depending on the configuration, while brushless DC motor (BLDC) spindles can reach 80,000 to 100,000 rpm. On high-speed industrial models, such as the 4033 Dc spindle with automatic direct-grip tool change, speed can reach 100,000 rpm for a power rating of 475 W. The ATC series includes an automatic taper change system for automated production processes, while the HFP series covers housing diameters from 48 to 105 mm for speeds of up to 60,000 rpm.
