Multi-Z-axis tapping engraving machine - metal aluminum parts processing
For the metal processing field, Weihong has specially launched a solution based on the NK530M/NK300CX CNC system, combined with Weizhi spindle driver + Weizhi servo driver + spindle motor/electric spindle. The system diagram is shown in Figure 1.
The main features of the Vihongduo Z-axis tapping system include:
• Reduces two positioning steps, significantly improving tapping efficiency;
• New generation axial servo motor, 24-bit multi-turn, shorter length, and better protection;
• Full bus control ensures precise and efficient tapping;
• The spindle servo supports most commercially available high-speed electric spindles, offering strong compatibility;
• Tailored to the specific characteristics of the industry, the axial servo and spindle servo employ a special three-proof process, resulting in a high level of protection.
In addition, the system can run the NC programs in each Z-axis independently and control the spindle machining independently without affecting each other; the powerful secondary development module can flexibly customize intelligent vision solutions according to the customer's production cycle.

3. Circular function
Surface machining and arc machining are prone to quadrant overshooting. Different arc sizes and different feed rates require different corresponding system compensation amounts.
Self-learning along the circle: By self-learning from machining at different radii and speeds, a compensation database is established. During machining, the system makes judgments to automatically compensate and eliminate backlash (Figure 4).

Circle adjustment: Manual fine-tuning of a specific circle is performed manually, and the adjustment can be visualized, with the size of the arc error directly displayed, greatly improving the adjustment efficiency (Figure 5).

Full-screen displays, foldable screens, cloud services, and the latest 5G technology are among the many cutting-edge technologies being incorporated into products. Every new product inevitably brings about significant changes in manufacturing processes, and each improvement in product processes inevitably places higher demands on the manufacturing industry.
