Description:
Features of NICE high-precision adjusting shims:
1. Product precision
Precision is the key requirement for adjusting shims.Accurate adjustment for fuel quantity si completed depending
on grouping of products.We adopt high-precision optical ruler to control lapping dimension,and can control product
precision dimension within 0.002mm.We finish grouping by inspecting one product with two products inside
dust-free workshop.One product is measured for no less than 5 times from finishing process to finished product.
(Testing methods:use high-precision digital display micrometer to measure conformity between actual dimension
and required dimension,and whether the dimension for same-grouped products is same or not.)
2. Geometric tolerance
Geometric tolerance of adjusting shims is directly related to the maintenance quality of fuel injectors.Main
geometric tolerance requirement for adjusting shims is depth of parallelism.Large shim will affect product
tightness while small shim will affect reliability and stability of products.We adopt high-precision double-sided
lapping machine to ensure and control depth of parallelism for products within 0.002mm.Adoption of one-time
forming process better ensures product axiality.(Testing methods:use parallelism tester and deflection instrument
to test parallelism depth and axiality respectively)
3. Material
quality and hardness Material quality and hardness of adjusting shims affect durability and stability
of products.We choose high quality material and advanced thermal treatment equipments/technology.
4. Cleanliness
