MB 600U: Compact CNC universal cylindrical grinding machine for workpieces up to 600 mm

The MB 600U is a CNC universal cylindrical grinding machine based on the MaiBase platform for high-precision internal and external cylindrical grinding of workpieces up to 600 mm. It was developed for applications where different workpieces and machining processes need to be implemented flexibly and economically on one machine – from single parts to series production.

  • M.+M. Mai software with GUIDE for guided and simple program creation on the workpiece
  • IPC operating system Windows 10 IoT
  • Hand panel with axis and speed selector switch
Base
  • FEM-optimized polymer concrete bed for maximum stability and durability
  • Mechanical separation of machine and peripherals for thermal stability and minimization of vibration influences
Tailstock
  • Up to 100 kg workpiece weight
  • MT3 and MT4
  • Stroke 20 mm (optional 60 mm and 120 mm)
  • Adjustment range +/- 30 µm
  • Pneumatic and hydraulic lift-off
Universal workhead
  • Applications with stationary or rotating spindle
  • Speed range 1 – 1,000 min-1
  • Roundness accuracy ≤ 0.001 mm (optional ≤ 0.0005 mm)
  • Oriented spindle stop
  • MT4, MT5 and MT6 available
Table/Slide
  • Linear guideway for X-axis, low-maintenance, high-precision
  • Low-wear sliding guideway for Z-axis
  • Optical position measuring systems on X- and Z-axis
  • High dynamics thanks to speeds of up to 8 m/min on Z- and X-axis
Ergonomics
  • Good overview of the grinding process
  • Centrally and easily accessible interfaces for table attachments
  • Thoughtful accessibility for cost-effective maintenance and service
  • Optional with automatic door opening
Load capacity
  • Cantilever 100 Nm
  • Between centers up to 100 kg (depending on variant)
Swiveling wheelhead (B-axis)
  • Significant reduction in non-productive times thanks to fast swiveling of the fully automatic wheelhead
  • Highest positioning and repeat accuracy through the use of a Hirth coupling

Thanks to its modular design and the swiveling wheelhead, the MB 600U enables versatile grinding strategies while reducing non-productive times. It is particularly suitable for complex grinding tasks on larger and longer workpieces with high demands on dimensional accuracy, surface finish and form accuracy.

The robust machine structure made of polymer concrete, high-precision guideways and modern CNC technology ensure high process stability and reproducible results – even on demanding components. At the same time, the machine offers excellent accessibility and flexible automation options.

Thanks to its versatility, the MB 600U can be optimally integrated into a wide range of production environments and offers a powerful solution for companies that require maximum flexibility combined with high precision.

Available with the following control

FANUC Oi-F Plus
