YK7163 CNC gear grinding machine is newly diveloped on the bases of our original Y7163 gear grinding machine,It is mainly used for grinding involute cylinderical gears,The use of CNC technology greatly simplifies the machine structure, eases its opeartion, extends its use, and is thus much helpful for furher improving its working accuracy. It is widely used in industries of machine tool, locomotive, vessel, mineral, and metallurgicalmachinery, etc.CNC controlled generating,indexing and feed.Special CNC realizes parametric programming which makes convenient and flexible operation.The full closed loop controlling function of CNC system is helpful to improve the working accuracy of the machine. Working accuracy is up to 4-5class/GB 100095-68.AC servo motor driving makes fast response, and large speed regulation rang e.The stroke speed of the grinding wheel is regulated whth a variable frepuency stepless governor gear.The wheel dresser can meet the needs of dressing for all kinds of modified gear profiles.
