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.
