Kovosvit MAS spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Kovosvit MAS spindles and motor spindles — a Czech manufacturer with a history dating back to 1939, and a reference in vertical machining centres and CNC lathes in Central Europe.
Kovosvit MAS, a Czech machine tool manufacturer since 1939
TLDR: Kovosvit MAS (Czech Republic, with a history dating back to 1939) has built a solid reputation in the manufacture of metalworking machines, with a range covering vertical machining centres (MCV series), CNC lathes (MASTURN series) and robust, reliable drilling machines.
Since 1939, Kovosvit MAS has built a solid reputation in the manufacture of metalworking machines in the Czech Republic. The manufacturer offers a complete range of vertical machining centres (MCV series), available in standard, Power (heavy-duty machining) and Speed 5AX (high-speed 5-axis machining) versions, as well as CNC lathes of the MASTURN series, dedicated to the precise machining of parts in steel, non-ferrous metals and plastic. The machines in the range are designed to deliver excellent precision and repeatability, with moving parts mounted on linear roller guides and position measurement by linear optical encoders.
A range of ISO 40 interface spindles, from standard to high-speed 5-axis
TLDR: Kovosvit MAS machining centres feature ISO 40 interface spindles mounted on angular contact precision bearings, with rotation speeds of up to 12,000 rpm and power outputs of up to 45 kW on the most dynamic 5-axis configurations.
The vertical machining centres of the standard MCV series feature an ISO 40 interface spindle, mounted on angular contact precision bearings and driven by Heidenhain AC numerical controls, with rotation speeds typically of 10,000 rpm. On the 5-axis configurations of the MCV Speed series, the spindle, manufactured by Kessler, can reach 12,000 rpm for a power output of 45 kW, combined with a rotary table with A and C axes for multi-face machining. On the CNC lathes of the MASTURN series, the two-stage spindle, driven by an asynchronous motor, enables efficient turning in two different speed ranges, optimally suited to the application.
