| Description |
This product is unique in that another copper product exists press-attached to the inner bore of the product by two-step drawing. The most significant point of this is how well they fit. For this reason, it is produced under tight tolerance conditions. Specifically, the inner diameter tolerance is from +0 mm to -0.02 mm and the decenter tolerance is 0.025 mm at maximum. Moreover, the product is tiny, with a maximum diameter of 1.20 mm and a maximum length of 2.30 mm. The most important priority is to maintain the precision of the metal die parts. |
