,Introducing the ZD-G400, an intelligent dual-head CNC milling and drilling center, masterfully crafted with the strength of HT300 gray cast iron. This machine boasts a double spindle and dual tool magazine for exquisite precision cutting. Its seamless electromechanical integration gives it an aesthetically pleasing and graceful design. With just a single clamping, it effortlessly and continuously performs a range of processes including milling, drilling, boring, expanding, reaming, and tapping.
This versatile machine is ideally suited for the intricate and varied processing of medium and small-sized box, plate, and shell-type components.
The machine's bed body is engineered with a high rigidity classic C-type structure, rigorously optimized through finite element analysis and topology optimization. This design innovatively shortens the stress path to significantly enhance rigidity. Crafted entirely from HT300 cast iron and subjected to half-stress annealing and natural aging, it ensures superior durability. The P-level straight rolling rails along the X, Y, and Z axes provide unparalleled stiffness, stability, and reliability.
2,Spindle: The cutting-edge double spindle system features a BT30 internally housed spindle, reaching an impressive maximum speed of 20,000 RPM, ensuring top-tier performance.
3,Knife library: This robust machine highlights a double knife library system, utilizing an arm-type mechanism to guarantee dependable quality and consistent performance. With clip arm replacement, the tool magazine holds a capacity of 21 tools, enabling swift tool changes.
Drive: The integration of a direct connection drive with the three-axis motor and high-precision ball screw elevates transmission rigidity and positioning accuracy. With linear rolling guides across all three axes, the machine exhibits minimal vibration at high speeds and zero crawling at lower speeds.
- The dual-spindle drilling and tapping center effortlessly processes two identical parts simultaneously, doubling efficiency and productivity.
- Equipped with a single, user-friendly numerical control system, this machine handles two units with ease, optimizing operation while conserving energy.
- The innovative double Z-axis structure allows for automatic compensation of tool length across both spindles.
- The dual spindle configuration masterfully handles milling, drilling, boring, tapping, and more on two identical parts in one go.
- Standard high-speed dual spindle rotation speed: an impressive 20,000 rpm/min, setting industry standards.
- Featuring a dual knife library setup, this machine executes rapid and automatic tool changes with ease.
- With a high-power cooling pump, the machine guarantees ample and efficient cooling capabilities.
- A fully sealed protective cover ensures unmatched safety and maintains a clean and hygienic working environment for operators.
- Equipped with a scour device, this machine ensures effortless cleaning and cutting operations.
- The automatic centralized lubrication system promises prolonged durability and efficiency of the wire rod guide rail.
- Precision and reliability in positioning assure superior processing quality every time.
- The powerful chip removal system effectively prevents chip accumulation, thereby reducing manual cleaning efforts significantly.
- With an extraordinary movement speed of 60m/min, it dramatically shortens non-cutting time, boosting productivity.
- Providing high-speed, stable processing capabilities, this machine is an outstanding choice for bulk production.
,Feed Mechanism
The X / Y / Z1 / Z2 axes are driven by a sophisticated feed mechanism that employs high-performance AC servo motors. These motors are ingeniously coupled with gap-less elastic couplings, which directly engage with the ball screws, ensuring seamless reciprocating motion across all axes. The wires are supported by a pre-stretched fixed structure at both ends, enhancing overall reliability and precision.
The power and torque dynamics are depicted as follows:
