Frequently Asked Questions - JBL-23F JILONG

What is the maximum number of cleaves the JBL-23F cleaver can perform?

The cleaver can perform up to 48000 cleaves in total, with each cutting point lasting up to 2000 cleaves. The blade has 24 rotatable cutting points.

What type of blade does the JILONG JBL-23F use?

It uses a tungsten steel blade with a diameter of 22 mm, thickness of 4 mm, and cutting edge length of 3.2 mm. The blade hardness is 91.50 HRA.

How do I replace the blade on the JBL-23F?

To replace the blade, rotate the cutting wheel to a new cutting point. When all 24 points are worn, the entire blade assembly should be replaced. Refer to the manual for detailed instructions.

What is the cleave angle specification?

The cleave angle is ≤0.5°, ensuring smooth and precise fiber end faces.

How do I clean the cleaver?

Clean the blade and holder with isopropyl alcohol and a lint-free cloth. Avoid touching the blade edges. Regular cleaning maintains cleave quality.

Is the JBL-23F suitable for single-mode and multimode fibers?

Yes, the cleaver is designed for both single-mode and multimode optical fibers, providing consistent cleave angles within specification.

What is the density and strength of the blade material?

The tungsten steel blade has a density of 14.75 g/cm³ and a transverse rupture strength (TRS) of 2200 MPa.

How can I contact JILONG for support?

You can contact Nanjing Jilong Optical Communication Co., Ltd at [e-mail] or visit www.JILONGOT.com. Address: 12F, Changfeng Technology Building 2, NO.14 Xinghuo Rd, Pukou District Nanjing, Jiangsu, 210032, China.

What safety precautions should I take when using the cleaver?

Always wear protective eyewear to shield from fiber fragments. Keep the blade out of reach of children. Handle the blade carefully to avoid cuts.

Can I sharpen or reuse the cutting points?

No, the cutting points are not meant to be sharpened. Each point is designed for a fixed number of cleaves (2000). Rotate to a new point when performance degrades, and replace the blade when all points are exhausted.
