TopTech Laser Cutting Tips IV

TopTech Laser Cutting Tips IV

-- Laser Cutting Accuracy Influence Factor

To tell the quality of a fiber laser CNC cutting machine is to see its cutting accuracy good or not. And to make sure laser cutting accuracy, each part of fiber laser CNC cutting machine is very important. There are a lot of influence factors to make sure one fiber laser CNC cutting machine’s cutting quality. Now TopTech would like to share 4 usually influence factors on fiber laser cutting machines. Hope our information can help you choose and maintain your fiber laser CNC cutting machines.

TopTech Fiber II laser CNC cutting machine

I. The shape of laser beam:

The shape of laser beam is a cone, so the cutting shape is a taper. With this situation, the kerf of 0.4mm thickness plate is much thinner than 3mm thickness plate. So the shape of laser beam is the most key point of laser cutting accuracy. With this cone shape laser beam, the thicker plate is, the lower cutting accuracy will be and the bigger kerf will be.

II. Kerf width:

When the cone shape laser beam focus together, the kerf will be thinner. So the fiber laser cutting accuracy will get better, esp. the kerf width will be thinner and thinner. At this situation, the min laser spot can reach 0.01mm. This is one of the factor influence on fiber laser cutting accuracy, too.

III. Machine body precision:

If the accuracy of fiber CNC cutting machine’s working table is uneven or other reason also can make fiber laser cutting quality not good.

Considering about this point is a big point, which influence on fiber laser cutting accuracy, TopTech Fiber II used heat treatment machine body to make sure every plate on machine is even. And the crossbeam is from a whole iron crossbeam, without any soldering parts on crossbeam.

Besides, TopTech Fiber II equip with German advanced Eckelmann EXC880 control system. It has inside laser head up & down control system. And with in Eckelmann control system it has IBE professional nesting software.

All these software and hardware of Fiber II is aim to make the fiber laser cutting accuracy as good as possible.

IV. Cutting material:

To cut different materials the cutting accuracy is different even with the same one fiber laser machine same one operator. Even though the material is the same kind of material, if their elements are different, the cutting accuracy is different.

In a conclusion, according to above 4 major points of influence factors on fiber laser cutting accuracy hope TopTech tips can help you understand fiber laser cutting accuracy more. And the maintenance of fiber laser cutting machine also can influence on fiber laser cutting accuracy. So when operator using fiber laser cutting machines, they need adjust the laser beam, the movement  way on working table. If you have special requires on fiber laser cutting, please feel free to contact TopTech. TopTech are willing to share the best cutting solution with you all.

TopTech FAQ plasma cutting quality & main reason

TopTech FAQ

plasma cutting quality & main reason

I. The cutting surface is not vertical:

When we use the common plasma power source to cut, the best one will have a small angle of inclination about 3-5°. If the actual angle is bigger than 3-5°, that belongs to the vertical is not good, and the reason is as following:

A. Torch installation is not vertical to the plates: if cut a symmetric figure the angle is the same side, that is this problem.

B. Cutting direction is incorrect: the required side should be on the torch forward right side.

C. Torch height is not good: Negative cut angle (the bottom side is less) means the torch height is too low; Positive cut angle (the top side is less)

D. Torch spare parts need to change;

E. Cutting current is not good;

F. Cutting speed is not good.

II. The drows on the cutting part:

A. The spater on the top side: the spater on the both sides of the kerf

  Reason: torch is too low

  Solution: adjust higher arc voltage value to heighten the torch.

B. The drows on the bottom side:

--Cutting speed is too slow, and the shape of the drows are bolls and a lot.drows can be easy to move out.

Reason	Solution
Cutting current too large	Reduce cutting current and use the matched spare parts for the torch
Cutting speed too slow	Faster the cutting speed
Cutting height too low	Adjust higher arc voltage value to heighten the torch

--Cutting speed too fast:,the drows are fine rolls, and hard to move out.

Reason	Solution
Torch nozzle broken	Change nozzle
Cutting current too small	Increase cutting current and use the matched spare parts for the torch
Cutting speed too fast	Slower the cutting speed
Cutting height too high	Adjust lower arc voltage value to heighten the torch

Otherwise, the bottom drows also considered about air pressure and flow setting.

III. Didn't cut through:

A. The first piercing spot didn't cut through and lead the shape didn't cut through: the pierce delay time is too short, should be longer;

B. The first piercing spot had cutted through, but the following parts didn't cut through:

Reason	Solution
Torch nozzle broken	Change nozzle
Rusting, paint or other insulators on the cover of cutting materials	Move out the insulators
Cutting current too small	Increase cutting current and use the matched spare parts for the torch
Cutting speed too fast	Slower the cutting speed
Plates too thick for plasma power source	Change into suitable plasma power source

IV. The min hole cutting rules:

• Rules: The hole's inner diameter should be twice as the plate thickness;

• To cut small hole the inside will be a taper hole.

TopTech Laser Cutting Tips III

--CO2 Laser CNC Cutting Machine

Laser cutting is a non-touching processing way to avoid machine pressure and have perfect working process on the surface. The super control system, Eckelmann EXC880, makes not only precision processing, but also sharp angle, small hole, and more complicated geometric figure cutting which can’t be done by traditional cutting die process. With advanced IBE nesting system inside Eckelmann EXC880 which adopt on TopTech laser cutting machines, it totally reduce human cost and material lost.

After more than 20 years development of laser technology updating and working process all over the world, laser cutting technology and laser cutting machines had been accepted and familiar with vast plates processors about high effective, high precision, perfect cutting finish of laser cutting process.

According to different types of laser sources, right now there are 3 main types of laser cutting machines: CO2 laser cutting machine, YAG laser cutting machine (also called solid laser cutting machine), and fiber laser cutting machine.

TopTech would like to share the differences, advantages of these 3 types laser cutting methods.

III. CO2 laser cutting machine

TopTech COLA CO2 Laser Cutting Machine

CO2 laser cutting machine can cut within 20mm carbon steel stably, within 10mm stainless steel, within 8mm aluminium alloy. The wave length of CO2 laser tube is 10.6um, which is easy absorbed by non-metal materials. It can cut wood, acrylic, PP, organic glass and other non-metal materials with high quality. CO2 laser’s light-electric percent conversion is only about 10%.

There is a nozzle at CO2 laser cutting machine’s light exit for injecting O2, compressed air or inert gas N2 to improve cutting speed and the cutting finish quality. To improve CO2 laser source stability and life time, the key point is to solve the issue of laser source releasing electric stability. CO2 laser belongs to lest damage on human body based on International safety standard.

ADVANTAGE of CO2 laser cutting machine:

CO2 laser power is very big. Normally the output power is between 2000-4000W, which can cut with in 25mm stainless steel, carbon steel and normal materials, and it can cut within 4mm Aluminuim plates and within 60mm acrylic boards, wood materials, PVC.

ATTENTION on CO2 laser cutting machine:

The key technology had held in USA manufacturers. Some Chinese manufacturers had got the same level technology of low CO2 laser power source. But CO2 laser cutting machine maintenance fee is very expensive and very difficult, the requires of operators is very high.

From 6-25mm middle thick plates cutting requires, CO2 laser cutting machine can be good choice, but also need to consider about the maintenance cost. With mature technology of fiber laser cutting machine, such as TopTech Fiber II laser CNC cutting machine, CO2 laser cutting machine will be taken over by fiber laser cutting machine in the future.

TopTech Laser Cutting Tips II

--YAG Laser CNC Cutting Machine

Laser cutting is a non-touching processing way to avoid machine pressure and have perfect working process on the surface. The super control system, Eckelmann EXC880, makes not only precision processing, but also sharp angle, small hole, and more complicated geometric figure cutting which can’t be done by traditional cutting die process. With advanced IBE nesting system inside Eckelmann EXC880 which adopt on TopTech laser cutting machines, it totally reduce human cost and material lost.

After more than 20 years development of laser technology updating and working process all over the world, laser cutting technology and laser cutting machines had been accepted and familiar with vast plates processors about high effective, high precision, perfect cutting finish of laser cutting process.

According to different types of laser sources, right now there are 3 main types of laser cutting machines: CO2 laser cutting machine, YAG laser cutting machine (also called solid laser cutting machine), and fiber laser cutting machine.

TopTech would like to share the differences, advantages of these 3 types laser cutting methods.

II YAG laser cutting machine

YAG Laser CNC Cutting Machine

YAG fiber laser cutting machine has low price, stable characteristics, but its energy efficiency is very low, normally less than 3%. Now YAG laser cutting machine max out put power is less than 8000W. Due to output power is small, YAG laser cutting machine usually be used on cutting thin plates’ holes. Its green laser light can be used with pules or continuous wave (CW). With short wave and good light focusing ability, YAG laser cutting machine especially used for precision process. And with pules it is most effective on spots cutting. And it also can be used on cutting, welding and marking functions.

YAG laser cutting machine’s wave length is not long, so it can’t be absorbed by non-metal materials. That is to say it can’t cut non-metal materials.

ADVANTAGES of YAG laser cutting machine:

YAG laser cutting machine can cut Aluminium plats and Copper plates and other color metal materials which other types laser cutting machine can’t cut. And the machine purchasing price is best, operation cost is low, maintenance is easy. As well as it has less limits on operators.

ATTENTIONAL on YAG laer cutting machine:

It only can cut less than 8mm materials, and the cutting effective is very low. YAG laser cutting machine’s pulse is like Xenon lamp, which usually max can be used 20 days. That is to say every 20 days, it need to be exchanged. Undoubtedly it is a huge expense. The lights mirrors are reflector, enlarge beam optic, protection optic, which are all important consumable parts of YAG laser cutting machine. If the machine maintenance well, these optics can be sued as long as 3 months, but to maintenance YAG laser cutting machine well is very difficult.

Within 8mm thickness cutting requires, YAG laser cutting machine would be suitable for color metal cutting, which can be used on household appliances, kitchen ware, decoration, advertisement manufacturing process.

YAG laser cutting machine will take over line cutting machine, punching machine, water cutting machine in the market.
