Heavy duty CNC roll milling machine

YCK-500CH Cnc Crescent Groove Milling Machine adopts advanced CNC technology and processing programming software, which makes the mechanical structure of the milling machine relatively simplified and reduces some mechanical transmission links. While the reliability, flexibility and high efficiency are comprehensively improved, the amount of maintenance is significantly reduced. 

The CNC crescent milling machine is a machine tool specially designed and customized for the steel industry. Application scope and requirements of processing: Precision rib groove processing of high-speed steel rolls, carbide roll rings, tungsten carbide composite rolls and ordinary rolls (crescent grooves, contour ribs, etc.), the machine tool automatically cuts rolls with different rotation directions and arbitrary helix angles The crescent groove can be divided into equal (or unequal) divisions or spaces in the circumferential direction of the roll; it can automatically engrave product specifications, grades, trademarks and other marks on any position of the roll.

The 4 NC drive shafts of the CNC crescent milling machine are equipped with SIEMENS fully digitally controlled AC servo motors. Because the AC servo motors have the advantages of high precision, maintenance-free and strong adaptability to the environment, the milling machine can work reliably in harsh field environmental conditions for a long time.

The drive chain of the cutter shaft is all grinded with 6-level precision to ensure that the tool track fully implements the program instruction requirements of the numerical control system, and eliminates the recessive defects such as groove mismatch and broken tool caused by the poor precision and rigidity of the drive chain. Especially in the processing of small size tungsten carbide roller rings, its superior performance is more prominent.

●  Basic crescent groove forming function: The tool bar axis of the flying cutter milling machine and the workpiece (roller) rotary axis form a 90º angle with each other, the tool bar spindle axis is placed at the center of the roll ring groove, and the tool bar head is located on the plane perpendicular to the workpiece axis and the tool bar axis. When the machine tool is working, the tool bar spindle and the roll complete the interpolation rotation movement, and the tool bar axis performs the feed movement toward the center of the workpiece until the tool bar spindle axis reaches the required center of the projection arc of the roll ring groove transverse rib (crescent groove).

● Basic milling method:
