The experimental table can conduct three types of dental sizes, displacement, force, and transmission efficiency of different spiral sidelines, and adopt advanced data collection transmission systems and data processing analysis software. One of the equipment.

Experimental project content:

1. Test the relationship between rectangular, trapezoidal, sawtooth spiral parameters and displacement;

2. The force test of the rectangular, trapezoidal, and sawtooth spiral spiral;

3. The transmission efficiency testing and analysis of the transmission efficiency of rectangular, trapezoidal, and sawtooth spiral;

M--n technical features:

1. The experimental table is driven by a DC speed regulating motor with a reduction. It is equipped with a clever design of the test parts and the adjustment mechanism. The input screw end is equipped with a torque speed sensor.

2. With three types of dental spirals, there are 5 guides of trapezoids, and two kinds of guidelines each with rectangular and jagged shapes. It is used to test the spiral transmission input torque and speed, and nut moving line speed of different dental guides to calculate its transmission efficiency.
