KN-113 ID GRINDER

KN-113 series are CNC controlled fully automatic cycle cylindrical grinders seeking after more performance, better rigidity, higher grinding efficiency and flexibility. the design roots were IZK's KN-111 and KN-112 series which are still reputed in various industries.


  KN-113 SERIES FEATURES

(1)

Both cross feed and spindle table employ V & Flat wide slide guide way which promise high rigidity as well as damped vibration.

(2)

Excellent CNC control system with sufficient memory capacity and easy operation enable "Menu" style condition setting. About 10 size Nos. of work pieces are registerable.

(3)

Equipped with rigid rotary disk dresser unit, tough wheel spindle and rich dressing menu, both Ceramic and CBN wheels are adoptable.

(4)

Various design of Autoloading device matches with steady function for wide variation of work piece form.

(5)


To maintain precise bore cylindricity, a stepping motor is furnished on the swivel base oh work table for revolving the swivel in "one -touch" operation. Also provided with "constant peripheral speed" function of grinding wheel to supplement its diameter wearing down.

(6)

Two choices of table traverse mechanism to meet the size and form of work pieces, i.e. Eccentric cam oscillation for higher frequency or Ball screw traverse driven by AC servo motor.

(7)

A whole machine cover "top deck" style prevents coolant splash leakage.

(8)

To protect coolant invasion into the slide table, higher slide position level and washout provision for bed face are setting.

(9)

To obtain easier operation when necessary, lower hight location of control switch/buttons are employed.
