How To Fix FAQ When CNC Laser Cutting Machine Works?

CNC Laser Cutting Machine have realized the upgrading and optimization of metal production. Today, with the continuous improvement of productivity, the manufacturing industry has more and more stringent product requirements. Quality and efficiency are the keys to enterprises to enhance market vitality and competitiveness. The Protective Fiber Laser Cutting Machine, intelligent high-end laser equipment enables production, excellent cutting level improves the quality and efficiency of enterprise production, and goes all out to carry the important task of stable production!

It is inevitable for users to face with some frequently-asked questions when CNC Laser Cutting Machine works. Let me tell you how to fix these questions easily.

IV. Laser output is weak after laser cutting machines work for a period of time

Please check whether focal length changes first, then, inspect the pollution state of focusing lens and whether laser path has any deviation. The most important thing is to check whether water circulation is smooth,  because laser cutting heat will disappear quickly only when the above circulation is good. In addition, it will be better if you purchasing laser cutting machines that offer high laser-conversion efficiency.

V. Abnormal sparks while cutting thin carbon steel sheets

As we all know, cutting sparks are usually long and even with less split while cutting thin carbon steel sheets. Abnormal sparks will certainly affect the smoothness and quality of workpiece surface. At this moment, nozzle depreciation shall be blamed for that if other parameters are within normal range. Please replace the nozzle, otherwise, increase the cutting gas pressure.

When screw thread between nozzle and laser cutting head becomes loose, please stop cutting to check the connection status of laser cutting head and thread up the screw.

VI. Piercing-through failure

Generally speaking, laser cutting machines adopt the pattern of blast piercing and pulse piercing. In view of better piercing quality of the latter, HSG prefers to the pulse piercing. During actual cutting, the piercing speed and quality are usually affected by machine power, focal length, nozzle position, cutting gas pressure, etc. Any improper handling may give rise to poor-quality piercing. In such case, you may change above cutting parameters, or adjust laser power, that is, change pulse width and frequency.

VII. Out-of-shape round hole or straight line

First of all, you need to check whether laser cutting control software is in normal work. Specific practice is to draw a straight line and observe whether laser cutting head moves in a straight line, so as to judge whether software should answer for that. Besides, the looseness degree of mechanical structure will also be detected. After that, you need to confirm whether this problem is caused by ultra-high laser energy.

Features of CNC Laser Cutting Machine:

• Manufactured by people who use their own machines.

• The resonator comes with a 100,000 hour warranty from the manufacturer (IPG)

• Higher cutting speeds possible

• Dual interchangeable tables allow for faster loading and unloading, reducing downtime

• Laser wavelength is one-tenth of a CO2 laser

• Reduction in cutting variables or tribal knowledge

• Fiber Laser is extremely efficient, equates to very low power consumption

• Low cost of operation, energy cost reduced, no laser gases requied to produce beam

• High cutting flexibility (Steel, Stainless Steel, Brass, Copper, Titanium, Aluminum, and more)

• Laser beam transmitted through a fiber optic.cable rather than with mirrors and channel tubing resulting in negligible power loss.

• Created and tested in a 100,000 sq ft Research and Development facility operating 9 metal cutting fiber Lasers, cutting 24/7.

CNC Laser Cutting Machine Application and Samples

Applications primarily suited for sheet metal processing. Such as various metal products processing industries, agricultural machinery industry, automobiles, aircraft and ships, electrical equipment, lighting advertising industry, elevator manufacturing, kitchen electrical appliances and so on.

Stainless steel guards

The working area is made using 304 stainless steel, in order to prevent damage to the surface stemming from the contact with sparks of high temperature, which are created during the cutting process.

Sliding gate made of annealed aircraft aluminium

The construction of the sliding gate is made of annealed aircraft aluminium, formed with a strength of 4300 tonnes, achieving unprecedented rigidity. Aircraft aluminium has many advantages: high rigidity (higher than cast iron), small mass, resistance to corrosion and oxidation as well as susceptibility to machining.

Dust-proof control case

All electric components and the source of the laser are built-into an independent control case with a dust-proof construction, in order to prolong the durability of electric components. The case is equipped with a cooling system for automatic constant temperature. This prevents any damage being done to the components.
