Attention should be paid to the optical axis positioning of stainless steel, which should be carried out according to the requirements in the process of processing and using.

Compared with the ordinary optical axis, the volume of stainless steel optical axis is relatively large, in this case, if the positioning is not accurate, the effective torque effect will become greater. And the measure to change this problem is to achieve positioning, and how to operate it concretely.
In general, if the mechanical load center of gravity and the screw center overlap state, should choose a smaller diameter of straight optical axis. If the stroke is relatively small, or the screw and shaft fixed installation, or the screw and shaft parallel to the case of good, small diameter products will be more consistent. But if the opposite is the case, the chosen optical axis should be thicker. The triggering principle of the long axis and the optical axis is to control the switch by judging the resistance of different resistance values formed by the light induction. When the handle is not pressed down to the OP value, because the optical path between the infrared light emitting tube and the infrared switch tube is blocked by the handle grating, the infrared switch tube will have no illumination and the resistance value will be infinite, equal to open circuit.
Linear guideways use four-row arc grooves, and coordinate with four-row beads and other 45 degrees of contact angle to achieve the purpose of bearing load in different directions to ensure the stability of the guide rail with higher rigidity.
