The base, column, spindle housing, cross slide, and worktable are all made from high-strength cast iron. These components undergo dynamic and finite element analysis to ensure maximum rigidity. The vertical machining system’s wide base, box-shaped column, and fully supported cross slide offer exceptional load-bearing capabilities, making it suitable for heavy-duty operations.

1. The belt-driven spindle comes with an external cooling system. The front-end features P4-grade precision angular contact bearings, while the rear is equipped with P4-grade roller bearings. This spindle, powered by a servo motor, reaches speeds of up to 8000 rpm for the ML-850 model (12,000 rpm for the MV-1160 model). It is ideal for both high-speed precision cutting and heavy-duty low-speed operations.
2. Equipped with high-performance grease-lubricated bearings, the spindle housing also includes an oil-cooled temperature control system to manage heat, minimizing thermal deformation during extended operation.
3. The powerful belt drive offers efficient, slip-free transmission and is easy to maintain.
4. The spindle assembly uses dynamic balancing technology to ensure smooth operation at high speeds, reducing vibration and ensuring precise machining results.

Both axes are equipped with P4-grade roller linear guides. The axes use hardened sliding rails with composite sliding supports, featuring high wear resistance and precision.

Fitted with a nitrogen gas balance system, ensuring stable movement even at high speeds. This balance mechanism provides optimal weight distribution between the counterweight and spindle box, allowing the Z-axis motor to maintain excellent load characteristics during machining.

1. All three axes are fitted with C3-grade high-precision ball screws combined with preloaded double nuts to ensure minimal backlash, delivering high accuracy.
2. The ball screws are supported by 60° angular contact bearings, ensuring smooth and precise motion during operation.
3. To reduce thermal expansion, the ball screws are pre-tensioned. This setup also enhances the rigidity of the transmission system, further improving positional accuracy during high-speed machining.
4. The ball screws are directly connected to the servo motors using flexible couplings, ensuring efficient power transmission with minimal backlash.
5. The pre-tensioning process increases the rigidity of the screws and eliminates issues related to heat expansion during fast movements, thus improving the machining system’s positioning and repeatability accuracy.

The vertical machining center is equipped with a 24-tool capacity arm-type tool magazine. The shortest path is automatically selected for each tool change, minimizing tool switching time. The dual-arm automatic tool changer operates via a motor and cam-driven mechanism, ensuring fast and stable tool exchanges. (Optional feature)

The machining center includes a fully enclosed protective system with a spiral chip conveyor, suitable for handling general metal and non-metal chips. For materials like cast iron and aluminum, optional chain or scraper-type chip conveyors can be integrated for more efficient waste management.

A centralized lubrication system ensures precise and consistent lubrication of the machining center’s guide rails. This pressure-relief system delivers the exact amount of oil required, preventing excess waste and ensuring smooth operation.

The machining system features an integrated oil-water separation system that collects waste oil from the lubrication rails into a rear-mounted tank. This prevents contamination of the cutting fluid and extends the lifespan of the coolant. (Optional feature)

Equipped with the Mitsubishi M80B CNC system, the control unit ensures stable and reliable operation. This machining system offers precise control over all CNC machining functions and auxiliary processes, allowing for accurate and efficient production.
