Laser cutting is a technology that uses a laser to cut materials, and is typically used for industrial

manufacturing applications, but is also starting to be used by schools, small businesses, and hobbyists. Laser

cutting works by directing the output of a high power laser most commonly through optics. The laser optics and

CNC (computer numerical control) are used to direct the material or the laser beam generated. A typical commercial

laser for cutting materials would involve a motion control system to follow a CNC or G-code of the pattern to be

cut onto the material. The focused laser beam directed at the material, which then either melts, burns, vaporizes

away, or is blown away by a jet of gas,leaving an edge with a high-quality surface finish. Industrial laser cutters are

used to cut flat-sheet material as well as structural and piping materials.

There are many different methods in cutting using lasers, with different types used to cut different material.

Some of the methods are vaporization, melt and blow, melt blow and burn, thermal stress cracking, scribing, cold

cutting and burning stabilized laser cutting.

Vaporization cutting

In vaporization cutting the focused beam heats the surface of the material to boiling point and generates a

keyhole. The keyhole leads to a sudden increase  in absorptivity quickly deepening the hole. As the hole deepens

and the material boils,vapor generated erodes the molten walls blowing ejecta out and further enlarging the hole.

Non melting material such as wood, carbon and thermoset plastics are usually cut by this method.

Melt and blow

Melt and blow or fusion cutting uses high-pressure gas to blow molten material from the cutting area, greatly

decreasing the power requirement. First the material is heated to melting point then a gas jet blows the molten

material out of the kerf avoiding the need to raise the temperature of the material any further. Materials cut with

this process are usually metals.

Thermal stress cracking

Brittle materials are particularly sensitive to thermal fracture, a feature exploited in thermal stress cracking.

A beam is focused on the surface causing localized heating and thermal expansion. This results in a crack that

can then be guided by moving the beam. The crack can be moved in order of m/s. It is usually used in cutting of

glass.

Stealth dicing of silicon wafers

The separation of microelectronic chips as prepared in semiconductor device fabrication from silicon wafers

may be performed by the socalled stealth dicing process, which operates with a pulsed YAG laser, the wavelength of

which is well adopted to the electronic band gap of silion.

Reactive cutting

Also called “burning stabilized laser gas cutting”, “flame cutting”. Reactive cutting is like oxygen torch cutting

but with a laser beam as the ignition source. Mostly used for cutting carbon steel in thicknesses over 1 mm. This

process can be used to cut very thick steel plates with relatively little laser power.

What is cnc laser?

CNC stands for ‘Computer Numerical Control’. That means computer has the ability to change the design patterns into numbers, produced by Computer Aided Design Software (CAD). These converted numbers control the movement of the cutter. In this way, computer controls the cutting and engraving of the objects.

A CNC Laser Cutter allows for extremely precise cutting and engraving of many materials such as wood, foam, concrete, different metals and many others. It contains a sharp and pointed router to produce clean and exact cutting of the material. This sharp cutter can even cut mo.

1. The manufacturing unit in the industries is very important. It is the part of production where

accuracy, time,less wastage of raw materials, and finishing play an important role. Everyone wants

to reduce the time of production, which means less time with mass production, with accuracy. Embedded

systems play a big role to sort out such things.

2. One of the examples of this system is CNC engraving machines. Engraving machines are

used in many ways such as furnishing, printing, cutting, marking, photoengraving the products.

Lots of engraving techniques are there. Modern engraving process includes laser engraving, CNC

engraving machines. CNC stands for Computer Numerical Control. CNC engraving machines will

reduce the need of workers cause most of the work it will do in automatic manner. Though for

that it must be programmed first.

3. Industry hires special operators for handling and the using of these kind of engraving

machines.To carry out the operations, regular machine tools are programmed with CNC machines.

The directions of the motions depends on the program set in CNC machines. This motion path may

be straight, circular or more complex. There isn’t any difference in the program written in CNC

machines, it’s just the set of instructions which are going to be executed step by step.

4. We can list out number of fields in the application of CNC machines. This may

includes advertisement industries; banners; photo printing, publishing house; cover printing;

fabrication, industries, metal removal industries, and furniture industries. Even though this

process may seem difficult,It is rather easy to those individuals that are already trained to

perform such tasks.

What is advantage of CNC laser cutting machine used in sheet metal cutting?

CNC laser cutting machine has advantages on sheet metal cutting.

The cut sew of CNC laser cutting machine is very narrow. Laser cutting machine cutting in high precision. The cutting sample can be used directly with no process.
It is very easy to arrange and modify the shape of fiber laser cutting machine. Especially for the complex sheet metal parts
The power density of laser cutting machine is large. Laser cutting machine cut sheet metal in short time. The heat-affected area is very small.So the deformation is very little. It is very suitable for sheet metal cutting.

how to choose the suitable CNC router machine?

1. Components’ quality is the basis of CNC router machines.

Usually well-known CNC router accessory brands are as below:

Spindle:imported Italy HSD air cooling spindle motor with ceramic bearings; China HUADIAO BRAND which is better than normal brands:hanqi,changsheng etc

if you want process hard materials you can choose constant power spindle motor which included 4 imported NSK bearings.

Control system: Taiwan Syntec; NC studio;Weihong NK105 DSP, MACH3,RZNC DSP.

Origional software: Artcut,UCANCAM,type3,artcam.

Motor and driver: Japan YASKAWA/Panasonic servo; Taiwan Delta servo; Leadshine stepper or Hybrid servo motor,YAKO driver  these are quality brands usually adopted on CNC Router system.

Inverter: Taiwan Delta; China Fuling/SUNFAR inverter etc usualy Taiwan Delta is more expensive than orther normal brands.

Guide rail: Japan THK, Taiwan Hiwin/PMI,China CSK etc we recommend original Taiwan imported is enough and good.

Ballscrew/gear rack: German Rexroth, Japan THK, Taiwan TBI etc Most China supplier adopt China made gear rack and TBI ball screw.

Machine body: this is very important.An heavy duty machine body with good rigidity can ensure the machine running stable without vibration this will determine the machine cutting/engraving quality

The more details they supplied more easy for you choose.

details configuration should be displayed in the contract.

2. Building technology determines the machines’ accuracy and service time.

When two CNC router’s parts almost are same, how should buyers choose one better?

So when you select high quality CNC router, choose a manufacturer with rich manufacturing experience is very important.

You can ask how they control the quality of machine?

how to ensure the machine parts accuracy and how to ensure the installment accuracy,repeat accuracy etc.All of the parameter should be have inspect instrument supported.

3. Good after sale service

If the parts broken what to do ? How to repare the machine quickly ?

we usually send the new parts to customer once the machine get broken and we need the broken parts get back

we recoomend customer prepare the easy broken parts with machine to avoid expensive courier cost once machine broken.

ensure the main spare parts price list before purchase the machine.
