OUTLINE

The KN-113 series is composed of CNC-controlled, fully-automatic cylindrical grinders that pursue high level grinding in terms of performance, rigidity, efficiency, and flexibility. The design is rooted from IZK's well-received KN-111 and KN-112 series.

KN-113 is traverse cut type. KN-213 is plunge cut type.

FEATURES OF THE KN-113 SERIES


(1) Highly reliable V-flat guide slides are provided but with a wider guide width. Through this, the feed table and wheel spindle table have better rigidity and damped vibration.

(2) A CNC device that boasts of user-friendly operations and big memory capacity are provided which help set the grinding parameters through a menu setting environment. A total of 10 job types ocan be registered.

(3) A highly rigid disc type rotary dresser unit, dress menu, and wheel spindle are built-in the machine that can adopt both ceramic and CBN wheels.

(4) Various automatic loading system designs are available to match the work piece form. Device matches with steady function for wide variation of work piece form.

(5) In order to maintain precise bore cylindricality, a step motor is furnished on the swivel base of the workhead table. Swivel movement is executed through a one -touch operation. Moreover, a "constant peripheral speed" function for the grinding wheel is provided in order to accommodate a stable wheel wear.

(6) Depending on the work piece width and length, two table traverse mechanisms are available to choose from :1) eccentric cam oscillation for higher frequency or 2) ball screw traverse mechanism driven by an AC servo motor.

(7) A whole machine cover "top deck" style is provided to prevent coolant splash.

(8) In order to prevent coolant infiltration into the slide table, the slide is designed higher than the bed. A machine-bed-washout provision is also provided for eliminating sludge build-up.

(9) The operation switches have been ergonomically set at a lower height level for easier access.
