The linear optical axis is an automatic technology transmission system part, which has the effect of correctly guiding the rolling bearing and realizing the uniform linear motion. When purchasing a linear optical axis, the most important thing is its performance. The following are the main points for judging the performance of the linear optical axis:
Straight optical axis
1. Raw material of straight optical axis: No. 45 steel is better, followed by high carbon steel, and medium carbon steel is slightly weaker. Of course prices will also vary.
2. Intensity of surface layer of straight line optical axis: Generally, the intensity of surface layer is above HRC58. More importantly, it is the uniformity of deep layer hardening and intensity of the whole surface layer. The intensity test ensures that the Rockwell plus or minus 2 degrees is qualified.
3. The flatness of the linear optical axis: it is related to the accuracy of the dominant. Generally, the manufacturer will straighten it when entering and leaving the warehouse, but the product with a very large height and diameter will cause bending during transportation or damage to its own net weight.
4. Linear optical axis electroplating process: The thickness of the high-quality electroplating process layer should be more than 0.02mm. Cheap products are likely to reduce the thickness of the electroplating process layer, resulting in spot rust in the case of long-term use.
Regarding the judgment of the performance of the linear optical axis, the editor will introduce it to you here. The completion of this uniform linear motion system software must have the following standards: simple design scheme; stronger execution ability; low-cost maintenance cost; application of durable raw materials that have undergone rigorous selection; precise diameter specifications; high frequency heat treatment process; true concentricity; true straightness and surface treatment.
