Laser Shield Cutter

Features of YVO4 Laser Processing

1Shield wire does not cut into the insulator

In the case of a mechanical stripper using a blade, cutting is performed while applying pressure on the shield wire from outside, and therefore, the shield wire cuts into the insulator. This may affect the characteristics of the cable. Being of non-contact nature, the laser does not affect the insulator.

Dedicated Cable Stripping Machine

1No uncut portions or damage on insulator

In the case of a 1-way irradiation device using a laser marker, or any other 2-way irradiation laser processing machine, there are portions that are not irradiated sufficiently by the laser, and also portions that are strongly irradiated. In this machine, the laser is irradiated from four inclined directions based on a unique device mechanism. The entire circumference of the shield is cut uniformly.

2Micro-processing and high-accuracy processing are realized

Through optimization of the optical design, beam-shaped laser irradiation that is suitable for shield cutting is performed, and this enables high-accuracy processing and micro-processing having very less heat damage on the circumference.

3Even micro braided wires do not require pre-soldering

A braided shield wire includes portions with double-wire thickness and portions with gaps as shown below. If the laser is irradiated, the shield wire that forms the inner layer in the double-wire portions remains uncut, and at the portions constituting the gaps, the laser permeates up to the inner insulator thus causing damage. Therefore, the extra labor of performing shield cutting after "pre-soldering" is required.

Since the 4-way laser irradiation enables uniform processing of the entire circumference by minimum laser irradiation, braided shield wires can be processed without leaving large scratches on the insulator even when pre-soldering is not performed.
