Currently, there are mature rolling mill mandrel crescent groove machining machines, mainly divided into two types based on structure and function: oscillating cutting milling machines with milling heads and spinning (fly cutter) cutting milling machines. Each type has its own advantages and disadvantages in terms of function and structure. We have innovated and developed the XK9350FA CNC spinning fly cutter engraving machine. This machine discards the overall replacement of oscillating cutting milling heads and spinning (fly cutter) cutting heads commonly used by manufacturers to achieve the structural scheme for switching crescent groove, text, and pattern processing. It employs a novel fly cutter slotting mechanism and a quick-change oscillating lettering structure for the milling head.
The fly cutter's transmission, positioning, clamping, and support structure employs a series of new functional structures, discarding the traditional worm gear and worm structure used in the high-speed rotation transmission components (worm gears and worms are prone to wear and failure in high-speed transmission, and their efficiency is low). This ensures efficient and rapid operation, with the fly cutter structure capable of processing transverse rib grooves and the fly cutter system offering good rigidity. It is stable and reliable. This structure has obtained a utility model patent certificate, a type of tool holder support block structure, patent number ZL2018217804827. This machine tool has obtained two utility model patent certificates, one for an adjustable center support structure, patent number ZL2018217798968; and one for an adjustable centering mechanism, patent number ZL201821779872.
The servo-driven flying knife transmission mechanism employs pure gear transmission (6th grade accuracy, ground), featuring high transmission precision, rigidity, and stability.
The milling head spindle features a variable frequency, stepless speed electric spindle with a power of 2.2KW and a high speed of 8000rpm. It can be equipped with a suitable speed based on the requirements of different materials to meet engraving needs.
Disassemble the support structure of the flying knife and it transforms into a milling head carving mechanism, convenient and quick.
The milling head employs a new type of rolling arc guide rail support, which resolves the rigidity issue of the head support while significantly enhancing the sensitivity and positioning accuracy in the rotational direction.
Numeric Control System Full-Automatic Programming, simple and convenient. You can adjust the cutting process and easily align the tool using the handwheel insert feature at any time during the machining process without having to stop.
