The model Y3132CNC4 heavy-duty CNC gear hobbing machine is of 4 axes CNC one, its control axes: axis X-radial feed motion; axis B-rotary motion of the hob spindle; axis C-rotary motion of the worktable and axis Z- the axial feed motion or with an extra axis Y- hob shifting controlled by A.C. motor. Its 4 axes coordinated control: B, C, X and Z. The model Y3132CNC5 heavy-duty CNC gear hobbing machine is of 4 axes CNC one, its 4 axes coordinated control: B, C, X and Z. An extra axis Y- the hob shifting is controlled by servo- motor. The series economic machines are designed to cut cylindrical spur & helical gears, crowning or slightly tapered gears, etc. and can bear capacity of heavy load under powerful and high speed cutting. It is suited for the industries that produce gears in mass production, such as automobile, engineering machinery, etc.
