XK8450HD CNC roll notching machine is suitable for processing cylindrical with diameter less than 500mm, length less than 2500mm roll, automatic processing of φ 5~ φ 60 screw steel roll of various specifications of crescent, high rib groove (GB1499-2017 standard). And according to customer requirements of automatic cutting different rotation direction, arbitrary helix crescent groove angle, can equal to any in the roll week (or unequal) indexing or spaces, but also can automatically seal product specifications, in the roll on any position grade, brand mark. Also can be arbitrary groove, text, marking processing of non-standard roller according to user requirement. The utility model can achieve the purpose of high automation, outstanding performance and multiple purposes of one machine.

XK84 series CNC roller notching machine adopts integral 4 guide structure of lathe bed, benchmark equipment with overall super audio quenching, outstanding guarantees the high rigidity, high precision and stability. The utility model can achieve the purpose of high automation, outstanding performance and multiple purposes of one machine.

The transverse moving guide rail of the "flying milling" adopts high precision heavy duty linear cylindrical rolling guide pair support (used on high precision CNC roller lathe). Ensure high precision and high rigidity of feeding motion in flying cutter.

Workpiece spindle drive with no gap connecting method, the maximum guarantee the transmission accuracy, control the reverse clearance.

The flying milling head and the swing carving milling head are arranged in parallel and centrailzed control. The operator only needs to select the simple machining mode on the CNC system, and the machine tool automatically realizes the function conversion without manual mechanical conversion.

The knife shaft transmission chain all use 6 grade precision grinding gear, to ensure the full implementation of program instruction tool path of NC system, eliminating the groove processing because the accuracy of transmission chain, poor rigidity caused by misalignment, broken knife hidden defects. Especially in the processing of small size tungsten carbide roll ring, it highlights its superior performance.

The main shaft of the fly cutter adopts the H40 type big diameter spindle end, which can meet the requirement of processing 60mm equal rib groove.
