Laser Shield Cutter

Features of YVO4 Laser Processing

1The shield wire does not cut into the insulation.

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. Shield cutting by the laser is non-contact nature. Since the depth of cut can be stably controlled, it is possible to cut up to half of the shield wire and remove the shield with a rotating brush type shield stripper (shield stripper SS-BV) without affecting the insulation.

2Reduces thermal damage to the insulation

Because of its low peak power and high repetition oscillation frequency characteristics, the YVO4 laser can reduce the amount of heat generated during processing the shield cable and reduce thermal damage to the insulation under the shield cable.

3No change in processing accuracy caused by component consumption.

Since there is no effect on processing accuracy due to wear of parts like blades, a constant processing quality and processing accuracy can be maintained for a long period of time.

Dedicated Cable Stripping Machine

1No uncut portions or damage on the insulation

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.

2A wide range of processing can be performed through a simple operation.

The simple operation involves only setting the workpiece and pressing the start button.

By combining together the "Laser processing conditions" and "Processing position conditions", changes in processing conditions by process and by product, and continuous processing of several locations can be performed through a simple operation of pressing the recipe selection button.


6 sets of laminated cables consisting of 32 AWG 46 coaxial cables can be processed in a single operation.

3Micro-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.

4Even 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.

5Numerical control of focus position adjustment

Numerical control of the focal position can be possible by a precision motor. The recipe can be registered according to the wire type and wire diameter, so you can only select the recipe to change the setup for small quantity and many kinds of products with different wire diameters! It is highly reproducible and there is no downtime during setup changes. Ideal to develop prototypes!
