[0023] Step 2: Slowly slide the sliding base plate 3 toward the fixed base plate 9, visually observe and adjust the two-axis slide table 5 until the needle gauge can enter the pneumatic chuck at the rotating end without obstruction. At this point, the concentricity positioning adjustment is complete.

[0024] Step 3: Set the MCU control unit to control the rodless cylinder to slide out of the sliding base plate to the left, loosen the fixed end pneumatic chuck 7, put the 3mm position of the tip of the bare file of the machine root canal file to be tested into the fixed end pneumatic chuck 7, and pneumatically clamp after confirmation.

[0025] Step 4: Set the MCU control unit to control the rodless cylinder to slide the sliding base plate to the right until the rod end of the bare root canal file enters the pneumatic chuck at the rotating end by 3mm. After confirmation, pneumatic clamping is performed.

[0026] Step 5: Start the torsion motor to conduct a torsion test;

[0027] Step 6: After the test is completed, collect the test data;

[0028] Step 7: Loosen the pneumatic chuck at the rotating end, slide the sliding base plate to the left, loosen the pneumatic connector at the fixed end, and remove the test bare file.
