SGC3163J2 Series
CNC Horizontal Gear Shaping Machine - SGC3163J2 Series

The Model SGC3163 is CNC Gear Hobbing Machines equipped with the Siemens 802D CNC system. The main drive is transmitted,at an infinitely variable speed,from a frequency-controlled motor. The X-axis and the Z-axis, actuated by independent AC servo motors,can be moved simultaneously.
The machines feature in reliable safety, short transmission chain,smooth running,robust structure,rigid transmission,less floor space coverage,wide range of applications and high performance--price ratio.

The Models YKN3163 is CNC Gear Hobbing Machines designed for cutting cylindrical straight gears,helical gears,sprockets and short spline shafts by the continuous indexing method. If required by the customer,the machines are capable of cutting workwheels by the radial power infeed method. The machines are also capable of cutting little tapered gear teeth,the crowned gear teeth and the like special gears.

The machines are versatile in functions and well adaptive to different applications. They are not only well-suited for batch production of gears in the manufacturing industies of automoblie,tractor,metallurgical machinery and transportation machinery,but also well-recommended for small batch production or jot-lot production of gears in the machine tools and machine-building industries.
