The key to the quality, speed and versatility of SPEEDFAM Double-sided Machine involves a principle known as the 4-way Motion. Utility of the 4-way Motion reduces machining time, surpassing the 2-way and 3-way Double sided machines. Here is how 4-way motion is achieved.
Direction of rotation of the lower and upper plates in relation to the carriers (1 and 2)
Rotational of the carrier in (3)
Axial spin motion of the carrier about the Center of lower and upper plates (4)
