High speed and high precision spindle: 1)With transmission of the high torsion tooth form leather belt, the electric machine works no slipping and escapes the emergence of noise and heat. 2)The main spindle turns at high speed with precise angular contact ball bearing and ball-bearing. The standard speed can be 8000r/min¡£ 3)Through cooling system, the high-performance oil spindle bearing, can control temperature rise effectively. 4)With the adjust equipment of ird dynamic balance, the main spindle can show high machining precision and escape resonance while working at a high speed. Plastic cloth for the first layer, canvas for the second layer and packing with wooden case at last, together with pallet on the bottom of woode box
