Core Engineering Advantages: Built for Complex Mold Geometries
Beyond general milling, the true strength of this series lies in its specialized components engineered exclusively for continuous, high-precision radial mold production:
Simultaneous 4-Axis Toolpath Integration
Driven by the premium SIEMENS 840D controller, the machine executes continuous synchronized motions across the X, Z, B, and C axes. This ensures the cutting tool maintains the optimal contact angle against complex segment molds at all times.
High-Speed, Ultra-Precision Spindle
Equipped with an advanced 30,000 RPM HSK-E40 spindle, it delivers the high-speed cutting (HSC) performance required to achieve mirror-like surface finishes, reducing post-machining polishing time by up to 70%.
Zero-Backlash Rotary System
The heavy-duty integrated C-axis rotary table features superior torque and stiffness, preventing micro-vibrations during heavy continuous machining of tough mold steel and aerospace-grade aluminum alloys.
High-Capacity Automated 24-Tool ATC
Designed for efficiency, the 24-tool Automatic Tool Changer supports seamless, uninterrupted automated machining cycles for highly detailed segmented mold inserts without human intervention.
Exclusive Applications: The Ultimate Engine for Next-Gen Tires
This machining center is strictly engineered to produce the entire spectrum of high-performance automotive tire molds:

- Aviation & Off-the-Road (OTR) Molds: Built to handle the high-strength materials and massive dimensions required for aerospace and heavy industrial tire applications.
Frequently Asked Questions on Tire Mold Machining
Is this machine suitable for processing modern Electric Vehicle (EV) tire molds?
Absolutely. EV tires are characterized by their extremely complex, narrow sipes designed to reduce road noise and rolling resistance. This requires incredibly fine cutting tools. Thanks to our 30,000 RPM high-speed spindle combined with the SIEMENS 840D controller's advanced look-ahead algorithms, this machine excels at micro-milling these intricate features without breaking micro-tools, delivering mirror-like finishes directly off the machine.
Why is a "Zero-Backlash" rotary system critical for this application?
When cutting tough materials like forged mold steel or aerospace-grade aluminum, the cutting forces can cause standard rotary tables to vibrate or shift slightly (backlash). Our Zero-Backlash rotary table is heavily preloaded to maintain absolute rigidity. This ensures that even during aggressive 4-axis simultaneous cutting, the toolpath remains perfectly stable, preventing surface chatter marks and ensuring the final tire mold requires minimal to zero manual polishing.
