Main Features:

This machine is a four-axis three-linkage CNC gear shaping machine in longitudinal layout that realizes the back-off motion by oscillating toolpost, the radial feeding by moving column, and the inclined back-off motion by laterally offsetting column parts. The control shafts include X-axis (Radial feeding motion), C1-axis (Cutter rotating motion), and C2-axis (Workpiece rotating motion). A variable-frequency and variable-speed motor is installed for the spindle to realize the stepless speed regulation of the main motion.

This machine is installed with standard SIEMENS 828D system and with common communication interface. The human-machine interface is applied to realize the parametric programming.

This machine can be used for shaping of cylindrical spur disc gears, multiplex gears, internal and external gears, and sector gears by continuous indexing method. Depending on the user’s needs, this machine can be used for machining of stem gears, helical gears, and small taper gears if installed with special accessories. This machine features following characteristics:

1. The large-plane mold injected slideways are used for the radial feeding of this machine to realize excellent drive stiffness, high support capacity, good shock resistance, low friction coefficient, and high guide precision and meet the high-precision repeated positioning requirement. The high-precision beveloid worm gear pairs are applied for the toolpost and worktable.

2. The machine incorporates the steady and reliable cutter stop function.

3. A simple and reliable adjustment mechanism is especially designed to compensate the inclination of cutter spindle vertical geometric position beyond the machine permissible error due to the wear of back-off cam and roller.

4. The optional static pressure toolpost (If installed), which includes static pressure slideways and static pressure bearings, can meet the need of high speed strokes and incorporate excellent precision retainability.
