M.+M. Mai machines:
Cylindrical grinding in perfection

Whether conventional or CNC controlled: M.+M. Mai cylindrical grinders process even complex workpieces with outstanding accuracy.  They are the ultimate solution when it comes to series production of high-precision workpieces for the automotive, aerospace and aerospace industries or medical industry. 


Their rigid main structures, high-precision guides, hydraulically operated slide adjustments and hydrodynamically mounted grinding spindles guarantee maximum precision and operational safety.
