,system

Equipped with the standard Mitsubishi M80 CNC system, this machine includes a specialized CNC CPU with exceptional high-speed processing capabilities.

,Machine tool bed body and the main body structure

The foundation of the Intelligent Dual-Head CNC Milling and Drilling Machine Center is a marvel of engineering with its patented dual-head drilling structure. This design empowers the machine with dual mechanical spindles placed on either side, allowing for versatile single or synchronous dual processing. The column, crafted as an integrated double-head rail structure, and the core structure, made from robust grey cast iron, ensure exceptional rigidity and shock absorption. Reinforcements within the bed body, coupled with a thick structure, fortify its strength. The grey cast iron transverse sliding table and worktable add to the machine's stability and precision, thanks to a large span design. The column base is meticulously secured to the bed through scraping and grinding, and the 'meter' tendon reinforcement structure within the column enhances both stiffness and earthquake resistance. This precision-engineered design substantially boosts column rigidity and minimizes forward tilt from the spindle box. Moreover, the spindle box features high-strength cast iron, providing unparalleled stability.
,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.

,Lead Rail

The guide rail system supporting the X / Y / Z1 / Z2 axes is a testament to cutting-edge technology, utilizing imported rolling guide rails. These rails provide tremendous rigidity and stability, endowing the machine tool with high precision and enduring accuracy.

,Principal Axis

Boasting a dual spindle configuration, this machine tool integrates advanced spindle units capable of remarkable rotation speeds up to 20000 rpm, delivering a maximum torque of 21 Nm. The spindle's front end is equipped with an air seal, complemented by a standard BT 30 spindle handle and a set of ten pull nails, enhancing functionality and performance.
The power and torque dynamics are depicted as follows:
 

,Lube Oil System

The entire machine's guide rails and wire bars benefit from a sophisticated quantitative pressurized concentrated dilute oil lubrication system. This system is capable of adjusting both the oil supply cycle and volume at each lubrication point. Through electrical system control, it achieves seamless automatic centralized lubrication.

,Coolant Passage

An optional spindle cooling system complements the standard tool cooling system. A large-capacity water tank, featuring an immersion multi-stage stainless steel centrifugal pump, facilitates comprehensive cooling of both tools and workpieces. Additionally, it is equipped with a flexible nozzle system for enhanced cooling efficiency.
