Product Description
The VMC855-D CNC Vertical Machining Center Delivers 12000 RPM Direct-Drive Spindle for Precision Mold & Aluminum Machining
Model: VMC855-D | Core Keyword: CNC Vertical Machining Center
CNC Vertical Machining Center Overview
The VMC855-D CNC Vertical Machining Center is a robust vertical machining center with a 12000 RPM direct-drive BT40 spindle, engineered for high-precision, high-speed operations. This milling machine handles workpieces up to 500 kg with 800×550×550 mm X/Y/Z travels, ideal for tight-tolerance manufacturing.
It excels in milling precision mold components, high-speed aluminum part production, and medical device machining. Its rigid structure also supports frequent high-speed drilling and tapping, delivering ultra-smooth surface finishes and maximum operational efficiency.
VMC855-D Key Features
- Rigid Machine Frame: Meehanite castings optimized via finite element analysis, with reinforced stiffeners, ensuring exceptional mechanical rigidity for heavy cuts and stable precision.
- Fanuc Control System: Standard with Fanuc Oi-Mf Plus control system, product quality design comparable to high-end global brands.
- High-Speed Direct-Drive Spindle(DD Spindle): ¢150mm BT40 spindle with FAG/NSK bearings, max speed 12000 r/min, delivering ultra-fine surface finishes for precision molds and aluminum parts.
- Stable Thermal Control: Forced circulation cooling system + spindle oil temperature cooler, maintains consistent spindle temperature to extend service life and preserve accuracy.
- 24-Position Tool Changer: Arm-type BT40 tool holder, supports max tool diameter 125mm (non-adjacent) and max tool weight 7 kg, reducing tool change time for high-volume production.

FAQ
Q: Can the VMC855 CNC Vertical Machining Center handle precision mold machining with 12000 r/min spindle speed?
A: Yes, the VMC855’s 12000 r/min direct-drive BT40 spindle delivers ultra-fine surface finishes, meeting the strict requirements of precision mold manufacturing. Its ±0.003 mm positioning accuracy ensures consistent tight tolerances, reducing post-processing work and boosting production efficiency.
Q: What are the advantages of a DD spindle compared to a BD spindle?
A: The motor of a DD spindle is directly connected to the spindle via a coupling. Without the vibration and noise caused by belt transmission, the machining surface texture is finer; it features fast rigid tapping speed, small start-stop inertia, and is suitable for frequent tool changes and high-speed cutting; there is no need to replace belts or adjust belt tension. However, since the motor heat is directly transferred to the spindle, it must be equipped with an oil cooler for constant temperature control.
Q: How should I choose between the VMC855 with a 12000rpm DD spindle and the one with a 10000rpm BD spindle?;
A: If your products are mainly aluminum alloy parts, small precision molds, or you require frequent high-speed drilling and tapping, and pursue ultimate efficiency and surface finish, choose the VMC855-D with a DD spindle. If your factory handles a wide range of jobs, often needs to machine hard materials (such as steel and stainless steel), or has a sensitive budget and pursues high cost-effectiveness and versatility, choose the VMC855 with BD spindle.
