Machining accuracy
|
measurement accuracy
(Processing measurement and quality control quality)
- Position accuracy guarantee: can reach ±0.0015mm. (including position, symmetry, inclination, verticality, parallelism, etc.)
-
Dimensional accuracy guarantee: can reach ±0.001mm (including
straightness, roundness, cylindricity, flatness, line profile, surface
profile, etc.)
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.
The comprehensive personnel experience can actually guarantee the following accuracy:
(including testing tools, instruments)
-
Aperture accuracy (∅1.5——∅30 ±0.002mm)
(∅31——∅60 ±0.005mm)
(∅61 or more ±0.008mm)
-
Pitch (or position ¤) (5-150mm ±0.003mm)
(152-250mm ±0.005mm)
(255-400 ±0.01) - Surface roughness: less than 0.4
-
Parallelism ‖, concentricity ◎, verticality ⊥ (150 or less ±0.003)
Symmetry ≡ (150-250 ± 0.005)
(250 or more ±0.01)
True roundness ○, cylindricity, area: within 200mm2, ±0.003
200-500mm2 ±0.005
500-800mm2 ±0.008
