Main Features:
Y7250CNC CNC gear grinding machine with worm grinding wheel is used for batch machining of hard tooth face cylindrical gear shafts and discs. It can also be used for grinding of the gears with axial modification, including the taper gears and drum gears, as well as the gears with tooth profile modification by modified diamond rollers. 
Based on the continuous generating grinding principle similar to the gear hobbing method, this CNC gear grinding machine with worm grinding wheel is equipped with Siemens 840DSL CNC system. Its main CNC shafts include toolpost angle (A), grinding wheel rotating (B), worktable rotating (C), cooling nozzle rotating (B2), dressing wheel rotating (B3), station exchange (CRT), radial feeding (X), tangential feeding (Y), axial feeding (Z), and tailstock vertical motion (W). This machine is a 10-axis 5-linkage machine. This gear grinding machine features the following advantages: 
1)The worktable, tailstock, and dresser are integrated on the rotating worktable. By means of the positioning of rotating worktable, the worktable (Workpiece) is rotated to the operator’s easily accessible area to ease the loading and unloading of workpiece. 
2)The displacement grinding method is applied. With maximum speed of grinding wheel spindle at 7,000rpm and the speed of the dressing wheel at 3,000~6,000rpm, this gear grinding machine can fulfill the high-speed high-efficiency grinding to remarkably improve the productivity. 
3)The advanced technologies, including electric spindle direct drive, grinding wheel online dynamic balance, and full-closed-loop control, are applied to remarkably improve the positioning accuracy, drive accuracy, and grinding accuracy and meet the high quality machining. 
4)The operating interface of the machine is in-depth developed on the basis of Siemens 840DSL, and is capable of the axial modification in any shape, which remarkably reduces the qualification of the machine operator.
5)The machine can be fitted with robot (trussed type or articulated type) and bin to further promote the automation level, improve the machining efficiency, and lower the labor strength of the operator.
