It is mainly used for grinding tungsten carbide roll ring, compound roll, high speed steel roll and R pass groove as coarse grinding, semi fine grinding,fine grinding and non spark grinding for high speed wire production. The shaped diamond grinding wheel is used to grind the hole and outer circle of the hard alloy roll ring, At the same time,numerical control control can be used to realize the R arc angle of the hole of the grinding hole .

The MK8450 CNC roll grinder mainly consists of a grinding wheel rack,a headframe, a worktable and a lathe bed.

The wheel frame is mainly provide the driving force of the wheel rotation, and the same time，it can move forward and backward.The wheel frame is moved before and after the movement of the ball screw. The guide rail adopts the direct guide rail support, which has high sensitivity, no damping and fast response speed, so the terminal negative feedback is realizes and the transmission precision is high.

The spindle motor of head frame can be controlled by frequency converter

The left and right sides of the worktable are driven by ball screw drive,fine pressure rail support,small damping,good vibration resistance and fast response speed.the upper work table adopts the inclined plane to support the head frame,which is convenient for drainage and at the same time using the weight of the headframe and the workliece on the guide rail.the headstock can automatically realize the parallel side of the headstock and the inclined side of the worktable.

CMK8450 CNC roller grinding machine, the body uses the whole 2+2 guide structure, that is, the horizontally layout of the bed four guide, four guide rail to provide the saddle and tail of the movement and positioning,and the front side of the front side of the bed to set a auxiliary guide as the auxiliary support for the saddle. This ensures that the saddle and tool holder have better rigidity and can bear greater cutting torque.

The bed guide rail adopts the whole super audio frequency quenching to ensure the micro abrasion of the feed parts,and maintain high accuracy and high stability for a long time. A certain height difference is designed between the saddle guide rail and the tailstock guide to ensure that the chip and coolant will not invade the saddle rail.

CMK8450 CNC roller grinding machine, the bed saddle holder adopts the adjustable body tool frame scheme and the gigantic swallow tail support guide, which greatly improves the stability of the tool holder. The tool carrier can improve the rigidity of the tool bar during the lathe turning process and reduce vibration. And adjust the position of the tool carrier to adapt to the roll processing of deep groove. This tool carrier scheme is very effective in the roll lathe of HERKULES company in Germany. When turning high hardness roll outer circle, the stability is guaranteed.
