● Detection tool:digital caliper or micrometer.
● Indicate the code for inspection.
● The number of outlet slots is 5×2.
● hole A is not roundness≤0.20mm,both sides of the hobbing plane of the parallelism≤0.20mm,no significant warping.
● hole hole anastomosis is not allowed to have a step,feel smooth and unimpeded.
