High-speed Gear Hobbing Machine Model
YS3120CNC&YS3132CNC
MIAN
FEATURES
The major structure members are of double-wall design
to ensure a nice rigidity;The AC spindle motor is directly mounted on
the hob head ,and the drive is transmitted to the spindle via three
pairs of high-precision cylindricial helical gears,thus minimizing the
transmission error and imprving the accurasy and rigidity of the
transmission.When the hob head is swiveled to a desired angle,it is
firmly clamped on the hob slide by the five-point clamping system.
The automatic tool clamping device has enabled the
machine to perform a quick and rapid tool-changing operation. The hob
shifting plate is hydraually clamped at multi-points.The hob head has a
short suspension length which provides a high body rigidity.
Big-diameter and high precision cylindrical gears are
adopted in the transmission chain and supported by high-precision and
high-rigidity bearings importedr from overseas.
The machine is equipped with a unique automatic
locking mechanism.An extremely high pressure force can be applied to
clamp the workpiece to assure a stable cutting accuracy.
All major slideways,featured in perfect vibration
resistance,strong bearing power.high guiding accuracy consistency,are
designed in large rectangular shape,inserted with steel strip,hardened
and coated with Teflon.
Heat sensors are installed at key positions of the
machine,and the temperature of cooling oil can be controlled by the
temperature regulator. The cooled oil runs back to and circulates in the
machine bed to create a nice thermal balance for the whole machine body
so as to obtain the desired hobbing accurracy.
The machine is equipped with a reliable trouble
locating system and thoughtful Safety protection facilities.
