CNC OD Grinding Machine GA27 & Cylindrical Grinder
Accessories
Hydrodynamic spindleThe grinding wheel spindle of this CNC OD grinding machine is made of high-grade alloy steel (SNCM220) by precision machining, including multiple heat treatments, grinding, polishing, etc. for enhanced durability. The spindle is supported by a unique hydrodynamic bearing to provide excellent rigidity and shock resistance. (End measuring device is optional.)
Rotary center / Fixed center head stock The simple and stable head stock is equipped with high-precision bearing, which greatly improves the rigidity and rotation precision of the spindle. Excellent waterproof ability enhances the durability of the machine.
Manual/Hydraulic tailstock The oil-filled type lubrication system of tailstock consolidates the waterproof and dust-proof abilities, and ensures the high-precision of tailstock.
CNC Control SystemIt is equipped with advanced CNC controller and form-filling type operation interface, and has editable standard grinding cycle program. It can also customize the dressing shape for special grinding request. It is easy to learn and understand.
