VMC855 Vertical Machining Center | 3-Axis Linear Rail CNC Milling Machine with 24T ATC

Description

The VMC855 vertical machining center is a high-performance 3-axis CNC milling machine with 8000 rpm BT40 spindle, 24-tool magazine, and linear guideways. Ideal for mold making, automotive parts, and complex metalworking with ±0.005mm repeatability.

The VMC855 Vertical Machining Center is a robust, high-precision 3-axis CNC milling machine designed for single-piece and batch production of complex parts. Built with a rigid cast iron frame, Taiwan HIWIN ball screws, and optional FANUC/SIEMENS/MITSUBISHI control systems, it delivers reliable performance for drilling, milling, boring, tapping, and cam/mold machining operations. The linear rail structure ensures fast traverse speeds and long-term accuracy, making it ideal for workshops and industrial production lines.

Core Advantages

✅ Ultra-Rigid Cast Iron Construction

All major components (bed, worktable, slide, column, spindle box) are made of resin sand castings with two aging treatments to eliminate stress. Optimized via SolidWorks and Ansys, the frame minimizes vibration and deformation under heavy cutting, ensuring consistent long-term precision.

✅ High-Speed BT40 Spindle Unit

Equipped with a Taiwanese high-rigidity BT40 spindle, driven by a 7.5 kW motor with speeds up to 8000 rpm. P4-grade spindle bearings and KLUBR grease lubrication ensure low heat and long service life, while spindle orientation and rigid tapping support full threading operations.

✅ Precision Motion & Control

X/Y/Z axes use HIWIN C3-grade double-nut preloaded ball screws with P4-grade 60° contact angle bearings. Rapid traverse speeds reach 40/40/24 m/min, with ±0.016 mm positioning accuracy and ±0.005 mm repeatability. The Z-axis servo motor includes an automatic brake for safety during power outages.

✅ 24-Tool Automatic Tool Changer (ATC)

Standard 24-tool magazine (16T optional) offers fast, reliable tool changes with minimal downtime. Hat-type or disc-type magazines with damping structures reduce impact, supporting tools up to Ø160 mm (adjacent) and 8 kg in weight.

✅ Complete Support Systems

Cooling System: High-flow pump with large-capacity tank, switchable water/air cooling, and M-code controlled nozzles.
Chip Removal: Split Y-axis protection with sloped bed surface directs chips to a pull-out drawer for easy cleaning.
Lubrication: Centralized automatic thin-oil lubrication with quantitative separators ensures even lubrication of rails and screws.
Safety & Protection: Full machine enclosure, rail covers, and pneumatic triplex filtration for reliable operation.
