According to the relative position of the rotor of the screw motor and the milling cutter, the coordinates of the helical tooth form and the cutter are-established.

Based on the finite element simulation technology to carry out the study for theory and structure of screw motor, it will provide some reference for the stator bushing's development and application.

Electrical system and temperature controlling system is designed by professional Taiwanese engineer; Heating wires and screw motor is imported from Taiwan, to ensure long hours working of the machine.
