What are the symptoms of failure to meet the design requirements of electronic universal testing machines?

The electronic universal testing machine is one of the precision testing machines. While paying attention to the internal configuration of the testing machine, we must also do a good job in the appearance. The generous appearance not only gives people a good impression psychologically, but may also reflect a company’s attention to details. Regarding the attitude towards the problem, if there are big problems with the appearance, then I believe that the quality of the product will not be trusted by users. Among them, the appearance of the electronic universal testing machine is unqualified as follows.

1. The paint and putty of the testing machine do not have sufficient strength, cannot resist oil and corrosion, and may peel off. 10. There are spots on the surface of electroplated parts, the coating is uneven, and there is peeling.
   2 The various labels on the testing machine are not clear. The electronic universal testing machine sign is not fixed in an obvious position. The fixed position of the sign is incorrect, uneven, unstable, and skewed.
   3 The unprocessed surfaces of all parts and accessories of the electronic universal testing machine are not primed and painted. Rust, molding sand, oil and other contaminants were not carefully removed before priming and painting. The painted surface is incomplete, not smooth, uneven and inconsistent in tone, with spots, wrinkles, bubbles and adhesions, etc.
2. The surface color of the blackened parts is uneven, with spots, rust, etc.
3. The color of the paint of the testing machine is not beautiful and elegant, the tone is not soft, the color registration is uncoordinated, the boundaries of different colors are not clear, and they contaminate each other.
4. There are rust, burrs, bumps, scratches and other defects on the processed surfaces of electronic universal testing machine parts.
   7 The countersunk head screw protrudes from the outer surface of the part, and there is obvious eccentricity between its head and the countersunk hole.
   8 The appearance of the electronic universal testing machine has bulges, depressions, roughness and other damage that are not specified in the drawings.
5. There is obvious misalignment at the edges of the joint surfaces of parts and components of the testing machine. Doors and covers are inconvenient to assemble and remove.
