CNC Internal Grinding Machine

CNC Internal Grinding Machine

Series: i GRIND 200

Elitech i GRIND 200 CNC Internal Grinding Machine is a high-performance CNC internal grinding machine built on a rigid rectangular cast body with cross roller guideways on both X and Z axes — ensuring high rigidity, low friction and ultra-smooth movement for long-term accuracy. Equipped with Siemens 808D Advanced or Fanuc 0i-TF Plus CNC controller, it is fully programmable for high-speed, high-cut internal grinding cycles.

Widely adopted in bearing and auto ancillary industries, the i GRIND 200 is optimized for mass production of high-precision bores up to 200mm OD clamping and 80mm grinding length. An optional twin spindle configuration enables simultaneous face grinding referenced to ID grinding — eliminating secondary operations.
