Machine tools automatically machine crescent slots with different helix directions and arbitrary helix angles to any desired pitch or spacing around the roller circumference (either equal or unequal). They can also automatically engrave product specifications, grades, trademarks, and other markings at any position on the roller. Additionally, they can process non-standard rollers according to user requirements for any slot type, text, and markings. Achieving a high degree of automation, prominent functions, and multi-purpose capabilities.

This series of machine tools features an integral 4-guide way bed structure. The reference guide way is treated with integral ultrasonic quenching, emphasizing the high rigidity, precision, and stability of the entire machine. Additionally, it incorporates a full-coverage protective structure.

The lateral moving guide rail of the fly cutter milling head components is supported by high-precision heavy-duty linear cylindrical roller guide pairs. This ensures the high precision and rigidity requirements for the feed movement during fly cutter processing.

The workpiece spindle drive employs a gapless connection method, ensuring maximum transmission accuracy and controlling reverse clearance.

The spinning milling head and oscillating engraving head are arranged side by side with centralized control. Operators simply select the processing mode on the CNC system, and the machine tool automatically performs the function conversion, eliminating the need for manual mechanical adjustments.

The Flying Knife shaft drive chain is entirely made with 6-grade precision ground gears, ensuring that the tool path fully complies with the program instructions of the CNC system, eliminating hidden defects such as non-alignment of slots and broken tools caused by poor accuracy and rigidity in the drive chain. Particularly, its superior performance is more pronounced in the processing of small-sized tungsten carbide roller rings.

The flying knife spindle utilizes a large diameter H40 spindle end, which meets the requirement for processing 60mm equal ribbing.

All longitudinal and lateral linear motion axes of the machine tool are equipped with high-precision ball screw drives to avoid the inaccuracies of gear rack transmission. Under the automatic control of the numerical control system, it can achieve automatic movement and precise positioning from one hole pattern to the next.
