Granite Surface Plate Calibration Procedure
All of the granite we use has been carefully measured to establish the modulus of elasticity, allowing us to comply and exceed federal specifications and user requirements.
Granite Surface Plate Calibration Procedure are a must for accurate measurement and provide a flat and stable environment for inspection. They are free from temperature distortion and offer an exceptionally sturdy measuring environment due to their thickness and weight.
Measuring on uneven surfaces can give incorrect or inconsistent inspection results, using a granite surface plate can help eliminate this problem.
Advantages:
• High quality material and precision machining process ensure product quality.
• A traceable QC system is worthy of your trust.
• Efficient warehouse and logistics management ensure your delivery time.
• A two-year warranty makes you without the worries behind.
Granite Surface Plate Calibration Procedure refers to the advanced standards of the leading countries, and its flatness tolerance is in accordance with the JB/T 7975-1999 Surface Plate:
Grade 000 =1x(1+d/1000)/μm
Grade 00 =2x(1+d/1000)/μm
Grade 0 =4x(1+d/1000)/μm
Grade 1 =8x(1+d/1000)/μm
(d is the length of the diagonal)
