measurement accuracy

Material and performance impact

It can ensure the positioning between the workpiece and the workpiece. The relative position and dimensional rotation can meet and meet the design requirements, and the hardness, strength, toughness, plasticity, wear resistance, corrosion resistance and service life of the material are not affected after processing.

Material and performance impact

The comprehensive personnel experience can actually guarantee the following accuracy:

(including testing tools, instruments)

  1. Aperture accuracy (∅1.5——∅30 ±0.002mm)
    (∅31——∅60 ±0.005mm)
    (∅61 or more ±0.008mm)
  2. Pitch (or position ¤) (5-150mm ±0.003mm)
    (152-250mm ±0.005mm)
    (255-400 ±0.01)
  3. Surface roughness: less than 0.4
