Six axis robot with BORUNTE pneumatic floating electric spindle

The application scenarios for the use of floating electric spindles also require the use of compressed air, and some specifications require water or oil cooling devices. At present, most floating electric spindles choose carving type electric spindles with high speed, small cutting amount, and low torque or DIY electric spindles as the driving force due to the pursuit of small volume. When processing larger burrs, harder materials, or thicker burrs, insufficient torque, overload, jamming, and heating are prone to occur. Long term use can also lead to reduced motor life. Except for floating electric spindles with large volume and high power (power several thousand watts or tens of kilowatts).

When choosing a floating electric spindle, it is necessary to carefully check the sustainable power and torque range of the electric spindle, rather than the maximum power and torque marked on the floating electric spindle (long-term output of maximum power and torque can easily cause coil heating and damage). At present, the actual sustainable working power range of floating electric spindles with maximum power labeled as 1.2KW or 800-900W on the market is about 400W, and the torque is around 0.4 Nm (maximum torque can reach 1 Nm)
