Cutting mild steel with a laser is a balance of how much material is heated up with the laser beam and how much assist gas flows through the cut. Heating up too small of an area or not having enough assist gas flow through the cut will result in the kerf width of the cut being too narrow.. Heating up too large of an area or having too much assist gas flow will result in the kerf being too wide.

Here, you can find solutions to the common problems of laser cutting machine and laser cutting process. Laser cutting is used to illuminate the workpiece with high power density laser beam,to make the workpiece rapidly melt, vaporize, abate or reach the point of ignition, at the same time, the molten material is blown out by the high-speed airflow which is coaxial with the beam to the workpiece, through moving light spot position by the CNC mechanical system to cut workpiece.

Laser cutting is an environmental friendly cutting method and has no harm to our body. Compared with ion cutting and oxygen cutting, laser cutting produces less dust, light and noise. Beware of flammable materials when using machine.

Some materials could not be cut by laser cutting machine, including foaming core material, all the PVC materials, high reflective material and so on.

In the machine working process, the operator is forbidden to leave to avoid unnecessary losses. Don't stare at the laser cutting processing. It is forbidden to observe the laser beams through binoculars, microscope or magnifying glasses. Which factors could effect the precision of laser cutting machine? There are many factors can affect the laser cutting accuracy, some factors are caused by the equipment itself, such as mechanical system precision, table vibration level, laser beam quality, auxiliary gas, nozzle etc, some factors are inherent material factors, such as the physical and chemical properties of materials , the reflectivity of the material, etc.

Other factors like parameters can be adjusted based on the specific processing object and the user's quality requirements, such as output power, focal position, cutting speed, auxiliary gas etc. Laser power density has a great influence on the cutting speed, so the selection of the focal position is particularly important.

The spot size of the laser beam is proportional to the length of the lens. There are three simple ways to find the cutting focus position in the industrial files:. Pulse method: Let laser beam print on a plastic sheet,moving the laser head from top to bottom,checking all holes and the smallest diameter is the focus.

Slant plate method: Using a slant plate under the vertical axis, moving it horizontally and looking for the laser beam at the minimum focus. Blue Spark: Remove the nozzle, blow the air, pulse on stainless steel plate, move the laser head from top to bottom, until find the blue spark as the focus.

How many types of laser machine have? Currently, lasers for laser processing manufacturing mainly include CO2 laser, YAG laser, fiber laser,etc. Among them, high-power CO2 laser and YAG laser have more applications in the confidentiality processing.

Fiber lasers with fiber-optic matrix have obvious advantages in reducing the threshold, the range of the oscillation wavelength and the tunability of the wavelength, it has become the emerging technology in the field of the laser industry. At present, cutting thickness of laser cutting machine is less than 25mm, compared with other cutting methods, laser cutting machine has a clear advantage in cutting material less than 20mm with high accuracy requirement.

Laser cutting machine has high speed, narrow width, good cutting quality, small heat affecting area and good flexible processing, so it is widely used in automobile manufacturing, kitchen industry, sheet metal processing, advertising industry, machinery manufacturing, cabinet processing, elevator manufacturing, fitness equipment and other industries.

Laser Cut Quality Guide

These high-power fiber lasers are a standard tool for metal laser cutting and. Figure: Two-dimensional cutting process, also called. Beam Parameters These are parameters that characterize the properties of the laser beam which include the … The laser cutting process. This is the process that we use here at SPI Lasers, due to the benefits that it provides over the other two laser processes. The sketch highlights the working principles of the laser-cutting process. The appli - cation of high-speed video diagnosis has turned out to be very instructive for a well-founded process analysis. The process of laser cutting involved many parameters, which can be generally divided into two main categories—beam parameters and process parameters [3,5,6].

About Blog Location. At All metallic materials and alloys are highly reflective to light waves: this feature is the main problem that needs to be addressed during a laser cut aluminum operation.. Laser cutting can improve quality and cut costs, but the result is scale on the edges of the steel which can often cause poor paint adhesion.

This was done using a focused CO 2 laser and an assist gas jet. The high strengthen character of stainless steel also make it not easy to be cut. For laser cutting and laser engraving architectural models a wide range of materials are used: textiles, synthetic materials, wood, veneer, MDF, PMMA, cardboard, paper, foam, polystrene, foils and films, acrylic, plastics, and many more.

 - Сьюзан не знала, как. Бросила взгляд на монитор, потом посмотрела на Грега Хейла.  - Сейчас. Несколькими быстрыми нажатиями клавиш она вызвала программу, именуемую Экранный замок, которая давала возможность скрыть работу от посторонних глаз. Она была установлена на каждом терминале в Третьем узле.

Первой из них были предоставляемые ею данные. Бринкерхофф терпеливо ждал, пока она изучала цифры. - Хм-м, - наконец произнесла.  - Вчерашняя статистика безукоризненна: вскрыто двести тридцать семь кодов, средняя стоимость - восемьсот семьдесят четыре доллара. Среднее время, потраченное на один шифр, - чуть более шести минут.

Сьюзан кинулась мимо Стратмора к задней стене и принялась отчаянно нажимать на клавиши. - Пожалуйста, - взмолилась. Но дверца не открылась. - Сьюзан, - тихо сказал Стратмор.

Solutions to the Common Problems in Metal Laser Cutting

Росио покачала головой: - Это. Но вам ее не найти.

 - Кассирша опустила металлическую шторку и скрылась в служебной комнате. Беккер шумно вздохнул и поднял глаза к потолку. Успокойся, Дэвид. Спокойно. Он оглядел пустой зал.

 Может быть, для того, чтобы вы не заподозрили, что это приманка. Может быть, Танкадо защитил его ровно настолько, чтобы вы на него наткнулись и сочли, что вам очень повезло. Это придает правдоподобность его электронной переписке.

Свернув влево, на Менендес-пелайо, он прибавил газу. Мотоцикл пересек крохотный парк и выкатил на булыжную мостовую Матеус-Гаго - узенькую улицу с односторонним движением, ведущую к порталу Баррио - Санта-Крус. Еще чуть-чуть, подумал. Такси следовало за Беккером, с ревом сокращая скорость. Свернув, оно промчалось через ворота Санта-Крус, обломав в узком проезде боковое зеркало.

ГЛАВА 107 Сьюзан понятия не имела, сколько прошло времени.
