Green Vine independently develops and manufactures double swing electric spindles. The maximum spindle speed can reach 12000rpm, with three linear motion axes of X, Y and Z and two rotary motion axes of A and C, and can realize any four-axis linkage.

Features

With constant temperature water cooler, spindle circulation cooling, tool center cooling, tool external cooling, stator coil in the spindle is sealed by “glue injection”, the spindle end face is hermetically sealed, the disc spring broach mechanism, and the claws are made of steel balls.

Features Description

The A-axis and the C-axis are driven by Taiwan’s HIWIN torque motor. They have the advantages of compact structure, large torque and no backlash. The water cooler is used to cool the torque motor to ensure the double-angle electric spindle for a long time. Stable operation under high temperature conditions. The HEIDENHAIN absolute rotary encoder is installed on the A-axis and C-axis to ensure indexing accuracy.
The front part of the main shaft adopts the patented multi-layer labyrinth seal design and air-tight design. The stator coil inside the main shaft is sealed by “glue injection”, which isolates the external coolant and makes the electric spindle have a longer service life. The stator of the electric spindle is cooled by a water cooler to ensure stable operation of the electric spindle under long-term and high-temperature conditions. The main shaft adopts nitriding treatment to improve the service life, and the main shaft and the rotor are dynamically balanced according to the G0.4 standard, thereby ensuring the stability of high-speed machining. The broaching mechanism of the spindle is tensioned by the German brand disc spring, which is more than 8 times longer than that of other manufacturers. The claw is made of steel ball tensioning sleeve structure, compared with the split claws used by other manufacturers. Strong anti-dust ability, simple structure and low failure rate.
