KN-213 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-211 and KN-212 series which are still reputed in various industries.
KN-213 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) |
2 types of table drive (hydrouric cylinder + stopper or AC servo motor + ball screw) are selectable to fit ground work width / length. |
(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. |
