1. BLANK’S FEATURE
a. Material: KZ-3YF
b. Sintered Particles’ Size Ave≤0.3um
(By intercept measured)
Sintered particles size is very vital for bending strength at FERRULE substance.
Reportedly, that size should be controlled within 0.3um.
c. Pore-Free
The refined Binder system materialized Pore-Free.
d. Inner diameter with the few taper (less than 3um)
The few taper of the inner part is able to produce the ‘SINGLE-MODE FERRULE’ well |
| efficiency. |
| Center-Less Polishing (when the process was beginning): |
|
| SC Type can be processed fromΦ2.62±0.03 toΦ2.55±0.005. |
 |
| LC Type can be processed fromΦ1.70±0.03 toΦ1.50±0.005. |
| |
| Steel Wire Setting |
 |
| When the metal of fixation, set wire size should be chosen properly for avoid of inclination |
| Ferrule Blank’s Line as small as possible; |
Length Cutting
SC Type: 10.6~10.8mm
LC Type: 6.8~7.0mm |
 |
★Pay attention to above points, the Single-Mode Ratio will over 80%.
e. Fine Concentricity
Our Blank with fine concentricity (refer to the attached inspection data with products) can be grinded |
| 100um at a time avoid wire’s injury. |
f. Color
Pearl like white |
