Processing workpiece range: Ф500×2500
Applicable roller thread specifications: φ5~φ50mm
Cutting method: "flying knife" cutting and processing of transverse rib grooves + milling head to engrave letters, numbers, and trademarks
Workpiece material: It can process ordinary chilled cast iron rolls, composite rolls, high-speed steel rolls and tungsten carbide roll rings.
1. This series of machine tools has a flat-V guide rail structure, super audio quenching, HRC48 or above, good rigidity, ability to withstand large cutting forces, good wear resistance, good guide rail accuracy, and good accuracy retention.
2. The transmission, positioning clamping, and support structure of the flying knife adopts a series of new functional structures, abandoning the traditional worm gear structure used in the high-speed rotating flying knife transmission parts (the worm gear is easily worn and fails during high-speed transmission. and low efficiency). It ensures high efficiency and speed, the flying knife structure processes transverse rib grooves, and the flying knife system has good support rigidity. Stable and reliable. This structure has obtained a national patent, and this machine tool has obtained 2 national patents.
3. The flying knife support structure draws on the characteristics of the same type of machine tools in Italy. The support block needs to be supported by an arc surface, which has a good support effect. The toolbar needs to be fixed with a spring chuck, and at the same time, a movable top is used at the top of the toolbar to support it. The support rigidity and precision of the tool holder.
The flying knife has high rigidity, high-precision support, and reasonable structure. See the picture for details:
4. The servo-driven flying knife transmission mechanism adopts pure gear transmission (level 6 precision, ground), with high transmission precision, high rigidity, and smoothness.
5. The milling head spindle adopts an electric spindle with variable frequency and step-less speed regulation, with a power of 2.5KW and a speed of 8000rpm. According to the needs of different materials, the appropriate rotation speed can be selected to complete the engraving needs. Removing the support structure of the flying knife converts it into a milling head engraving mechanism, which is convenient and fast.
6. The engraving and milling head need to be supported by the latest rolling arc guide rail, which solves the rigidity problem of the milling head support and greatly improves the sensitivity and positioning accuracy in the rotation direction.
7. The automatic programming software developed by our company and Siemens is embedded in the CNC system. You only need to input parameters such as roll diameter and specifications, and the crescent groove processing program and engraving program will be automatically edited and generated. Reduces tedious programming work and improves processing efficiency. During the machining process, you can use the handwheel insertion function to adjust the cutting process at any time without stopping the machine, making it easier to set the tool.
