The Model YKX39320 machine is external tooth milling machine; the model YKX39320N machine is internal tooth milling one. Both of them are of 5-axis control ones. Based on the principle of single-index forming milling, the machine are able to cut helical gears with Z- and C-axis coordinated control. They are designed for manufacturing spur gears, helical gears (sharft, disc and internal gears) and slightly tapered & crowning gears with larger diameter, etc.

The machines have the features of high efficiency and rigidity. They are specially used for the industries to manufacture gears, such as wind power, engineering machinery, large-sized speed reducer, etc.
