This will redound the system the ability of high rotational speeds for manufacturing light materials such as wood or plexiglas.
It also enables the usage of relatively small and lighter materials.
· The spindle motor always work in high power ratio zone even if manufacturing hard materials which are needed to be manufactured at low rotational speeds
For future work, different materials which posses more durability and flexibility, would be tried in order to make this system more efficient.

Introduction To meet the increasing demand for energy and overcome to materials the limited availability of fossil, photovoltaic solar energy production, will become increasingly important.
But this compound contains expensive materials such as (In)) and (Ga) and toxic element such as (Se) [3].
From these unique features, CZTS is expected to be one of the promising materials for thin film solar cell.
