1. This is a 4-axis CNC machine: the cradle roll (X-axis), the workpiece rotation (Y-axis), the sliding base feed (Z-axis) and the reciprocating movements of the cutter (S-axis).
2. The machine cuts gears with the Generating Principle, of which the gear being cut makes relative rolls repeatedly together with the imaginary generating gear (represented by the reciprocating movements of the cutter).
3. The cutter head is mounted on the cradle and the gear being cut is mounted on the spindle. The indexing box is located on the sliding base, and the cradle and the sliding base are fixed on the machine bed.
4. Two cutters with linear cutting edges are mounted on the cutter head and make reciprocating linear movements together with the cutter head.
5. A connecting rod mechanism is adopted on the cutter head, which is driven by means of a variable-frequency motor to make the reciprocating movements of the cutter.
6. High-precision worm and worm wheel pairs are used for both cradle spindle and indexing box spindle, which are driven by means of servo motors.
7. A ball lead screw, driven by a servo motor, is used for the feed movement of the sliding base.
8. SIEMENS 828D CNC control system is equipped for the machine.
9. A full-enclosure with good visibility and anti-oil splash and automatic chip conveyor are equipped on the machine.
10. An independent and sealed electrical cabinet with an air conditioner is equipped for the machine.
