I. Abnormal Accuracy Repeatability Accuracy: If the dimensional deviation exceeds ±2 micrometers after 10 consecutive measurements of the same

I. Mechanical Reference Calibration Prevention Platform Leveling: Use a level to calibrate the worktable surface, ensuring a verticality error ≤ 0.

1. Inaccurate mechanical reference calibration: Key indicators such as perpendicularity and concentricity may not meet standards, possibly due to equi

I. Preparation before calibration Tools needed: Level (accuracy 0.02mm/m), feeler gauge (0.01-1mm), marker, thin barley paper, cotton cloth. Equipment

I. Basic Accuracy Verification 1. Repeatability Test: Measure 20 times consecutively using a standard part. The repeatability accuracy should be ≤0

I. Pre-test Preparation Tool Preparation: Use a temperature sensor with an accuracy ≥ ±0.1℃ (regular calibration required), and set up 9-15

1. Preheating Stage Preheating Temperature: Set according to material type. For metal parts, 100-120℃ is recommended. For plastic parts, the melting t

1. Temperature Control Preheating and Welding Temperature: Preheating temperature, welding temperature, and time must be set according to the material

I. Parameter Setting Optimization Temperature Control: Set preheating temperature, welding temperature, and time according to material type (e.g., met

1. Color Dot Method: Apply red lead powder evenly to the surface to be measured. After rubbing it on a standard plate, bright spots will appear. Withi

1. Flatness Inspection Methods Color Dot Method: Cover the working surface with a 25×25mm square hole plate and count the number of contact spot
