500mm CNC straight bevel gear generator

The machine adopts Huazhong 8 CNC system, three axes and two linkage, machining straight bevel gear CNC machine tool, suitable for automobile, agricultural machinery, aviation and machine tools and other machine manufacturing departments in batches, small batches and single parts production.

This machine tool is processed with two standard planer knives according to the hypothetical flat-top gear principle. Rough cutting and fine cutting can be carried out on the same machine tool. Rough cutting adopts the cutting method, the working mode selects the position of "planer", and the mode of shaving selects the position of "coarse cutting". By rolling cutting method, the position of "planing tooth" is chosen by working mode and the position of "fine cutting" is chosen by gear shaving mode. After NC starting, the gear blank must withdraw quickly from the cutting position, which must be greater than the upper position of the tooth (the back shift of the saddle, that is, the positive movement of Z axis). After the rocker returns quickly (the rocker rotates clockwise X to the pendulum angle), the gear feed (saddle forward, that is, the negative Z axis movement) to the gear feed (bed saddle forward, that is, Z axis negative movement) to Rolling position, X axis Y axis linkage, so that the cutter and the tooth billet roll each other (rocker counter-clockwise X-rotation, workpiece head clockwise Y rotation), rocker table rotation to swing angle, this tooth finish, the blank out of the cutting position, Must be greater than the top of the tooth (saddle backward, that is, Z axis forward movement), the rocker table fast return (the rocker table clockwise X rotation to the pendulum angle), the workpiece head fast return (counter-clockwise Y-rotation to the beginning of the tooth position), after the rapid return of the workpiece head (counter-clockwise Y-to the beginning of the tooth), The tool head rotates a indexing angle clockwise to realize automatic gear splitting. The next tooth is then processed, and the blank is fed to the roll-off position (saddle forward, that is, negative Z-axis movement). Oh, keep shaving your teeth. This circulates until all gears are cut and the machine stops automatically.
