CM 12H

The Abwood CM12H utilises a high power single spindle to remove material from the bottom or top of sawn multi-crystalline blocks. This maybe used as an alternative to saw cropping of block ends where the material to be removed is minimal.



  • Four Spindle Simultaneous Grinding for reduced cycle time
  • High pressure coolant system for maximum wheel life
  • Low cutting forces result in reduced sub-surface damage for improved wafer yield
  • Full CNC control system for ultimate machine flexibility
  • Integrated laser measuring system for in-process component inspection
  • Cost effective alternative to standard industry sawing equipment


High Material Removal Rates

A 15kW spindle motor coupled with a very coarse super-abrasive wheel allows for material removal rates of over 1000mm3/s. The result is that it is possible to process 10 multi-crystalline bricks per hour with removal of up to 10mm in total from the ends of the block.
