When the double-head cutting machine for aluminum alloy profiles cuts industrial aluminum profiles or aluminum alloy profiles with thermal insulation and broken bridges, JMD Machine reminds customers to pay attention to the following points:
Application range of aluminum alloy profile double-head cutting saw: aluminum profile CNC cutting saw adopts soft transmission technology, magnetic ruler positioning, Chinese touch screen display
- Pay attention to the spray device. When cutting thick aluminum profiles, the spray device is essential for the protection and cooling of the saw blade. Some customers do not care about this, but now the price of a saw blade is not Fei, if you don’t pay attention to this piece, the loss of the saw blade will be very large. Save the frequency of blade replacement as much as possible.
- Pay attention to the setting of the pressing device. According to the shape of the profile, adjust the profile pressing device appropriately, so that the saw blade can ensure that the profile does not shift at the moment of contact with the profile, which is the premise to ensure the cutting accuracy.
- Pay attention to the stability of the power supply voltage and gas source, which we have mentioned in the previous article, pay attention to it at any time, and strengthen the sense of responsibility of the operator.
- Pay attention to the cleaning of waste, which is very important to ensure that the blockage of the solenoid valve causes poor commutation.

Aluminum alloy doors and windows are very common in life. Aluminum alloy doors and windows are the best choice for ventilation and blocking mosquitoes and flies. However, after a long time, the screen windows will become very dirty. How should we clean the screen windows of aluminum alloy doors and windows?
Cleaning the invisible screen windows with grease in the kitchen
- First use a soft brush to gently brush off the floating dust on both sides, then use two sponges or plastic foam, dip some washing powder solution or soapy water, hold one in one hand, and clamp the same part of the screen from both sides, First wipe from top to bottom, then left to right; finally, dip in water and wipe gently, so that the dust on the screen window can be completely removed.
- A very affordable and environmentally friendly method: dilute the flour with water.
Note: (1) The water should be boiled water; (2) The proportion of flour and water is appropriate, and it is enough to make the paste water. When the paste water is slightly cool, mix in an appropriate amount of washing powder (depending on the amount of grease), stir well, use The special brush for Feng screen window directly brushes the paste water on the screen window, and taps after drying, the grease and stains will fall off together with the flour.
Cleaning of invisible screens without grease
- The aluminum alloy doors and windows adopt the method of wiping while pulling, and some invisible screens are folded. If all the screens are pulled out and wiped all at once, the screens are likely to be damaged, and it is very difficult to Convenience. We can wipe as much as we can to pull out the gauze (use a sponge when wiping, and use the sponge’s dust absorption function, so that the dust will not fly around).
- If you have an old newspaper at home, take it out, soak it in water (preferably with a lot of words) and stick it on the screen window, take it off after a while (don’t wait for the newspaper to dry before taking it out), do it several times, The windows are clean.
- Vacuum cleaning method: first close the glass window outside the screen window, then put a large newspaper between the glass window and the screen window (or hold the newspaper with your hands to prevent the newspaper from flying around), and then stick it with a vacuum cleaner. Put on the screen and suck the dust off bit by bit.
With the continuous development of society,broken bridge aluminum alloy windows and doors are more and more widely used in decoration.broken bridge aluminum alloy windows and doors are aluminum doors and windows made of thermally insulated broken bridge aluminum profiles and insulating glass, which have outstanding sound insulation effects, Dustproof and waterproof, etc., So, are there any disadvantages for such a good performance of broken aluminum doors and windows?
Advantages ofbroken bridge aluminum alloy windows and doors:
1. Reduce heat conduction: The use of insulated bridge-broken aluminum alloy profiles and hollow glass structure effectively reduce the heat conduction through doors and windows.
2. Prevent condensation: The temperature of the inner surface of the profile with heat insulation strips is close to the indoor temperature, reducing the possibility of indoor moisture condensation on the surface of the profile due to oversaturation.
3.Energy saving: In winter, window frames with thermal insulation strips can reduce 1/3 of the heat lost through the window frame; in summer, if it is air-conditioned, the window frames with thermal insulation strips can Reduce energy loss more.
4.Protect the environment: Through the application of heat insulation system, energy consumption can be reduced, and the environmental radiation caused by air conditioning and heating can be reduced at the same time.
5.Good for health: The heat exchange between the human body and the environment depends on the temperature of the indoor air, the air flow speed and the temperature of the outdoor air. The most comfortable environment has been achieved by adjusting the indoor temperature of doors and windows so that it is not lower than 12～13℃.
6.Noise reduction: The use of hollow glass structures with different thicknesses and a cavity structure of thermally insulated aluminum bridges can effectively reduce the resonance effect of sound waves, prevent sound transmission, and reduce noise by more than 30dB.
7.Colorful colors: aluminum profiles of different colors can be produced after surface treatment with anodizing, powder spraying, and fluorocarbon spraying. After rolling and combining, the insulated aluminum alloy doors and windows can produce indoor and outdoor two-color windows with different colors.
Disadvantages of broken aluminum doors and windows: complex production and expensive.
It can be seen from the article that there are still many advantages of broken aluminum doors and windows, including reducing heat conduction, preventing condensation, reducing noise, etc., reducing energy loss can also protect the environment and benefit physical and mental health. Of course, everything is There are two sides. Although it has so many advantages, it also has its disadvantages. It is not easy to make, and the combination of advantages and disadvantages also indirectly leads to its price is not cheap.
]]>The quality of aluminum door and window machinery can be roughly judged from the selection of raw materials, the quality of aluminum surface treatment and internal processing, and the price of aluminum door and window machinery.
1.From the point of view of materials, the thickness, strength and oxide film of high-quality aluminum door and window machinery should meet relevant standards. The wall thickness should be greater than 1.2 mm, the tensile strength should reach 157 Newtons per square millimeter, the yield strength should reach 108 Newtons per square millimeter, and the oxide film thickness should reach 10 microns. If it does not meet the above standards, it is a low-quality aluminum alloy door and window equipment and cannot be used.
2.Look at processing. High-quality aluminum alloy door and window equipment, fine processing, exquisite installation, good sealing performance, and convenient opening and closing. Inferior aluminum door and window machinery blindly choose aluminum profiles and specifications, rough processing, sawing instead of milling, not installed as required, poor sealing performance, difficult to open and close, not only leaking wind and rain, cracking the glass, but also when encountering strong winds and external forces , It is easy to scratch or knock off the sliding parts or glass, and damage things.
3.Look at the price. Under normal circumstances, due to high production costs, the price of high-quality aluminum door and window machinery is about 30% higher than that of inferior aluminum door and window machinery. The tensile strength and yield strength of some aluminum alloy doors and windows made of aluminum profiles with a wall thickness of only 0.6-0.8mm are far lower than the relevant standards and are unsafe to use. In addition, there are currently many self-employed individuals who process aluminum alloy doors and windows and do not understand the structural characteristics and performance of aluminum alloy doors and windows.
4.The current standard profile thickness is 1.4mm. If the supplier chooses a material with a wall thickness of 1.2mm or 1.0mm or even thinner, it is an unqualified product. Please pay attention when buying.
]]>Under normal circumstances, aluminum alloy cutting saw blades are used inlaid alloy saw blades, and the saw blades are inlaid with cemented carbide. For the tooth profile, the saw blades for cutting aluminum alloy are all ladder flat teeth.
For different aluminum alloy materials, the number of teeth used by aluminum alloy cutting saw blades is very different. Of course, generally speaking, the thicker the material wall to be sawed, the fewer the number of teeth of the aluminum alloy saw blade used. Because the effect of chip removal needs to be considered, the fewer teeth, the better the chip removal effect. However, some aluminum alloys have certain requirements on the cutting surface and cutting smoothness. If the processing accuracy of the steel plate and alloy head of the aluminum alloy saw blade is not particularly high, the saw marks are prone to appear, and the surface is not so smooth.
Therefore, for the sawing of aluminum alloy saw blades, relatively high-demand alloy saw blades are used; and the selection of the number of teeth of aluminum alloy saw blades will also affect the sawing effect. The effect of the cutting surface, normally, the more teeth, the smoother the cutting surface, but conversely, the worse the chip removal effect.
However, for aluminum alloy processing, the general thickness is within 10 mm; the cutting width is within two to three hundred mm. Generally speaking, 120-tooth or 100-tooth aluminum alloy saw blades are used. For aluminum alloy materials, if the thickness is more than 20mm, 80-tooth aluminum alloy saw blades are generally used. If the thickness is more than 40-50mm, most of them are sawing with 60-tooth aluminum alloy saw blades.
When your windows and doors are not in normal use, your aluminum alloy windows may face the option of repair or replacement.
Knowing four common aspects can help you make informed choices.
Unqualified installation.
Whether the installation of windows and doors is standard or not will directly lead to the use effect and service life of doors and windows. Non-standard installation must be paid attention to.
In judging whether the installation of windows and doors is standard or not, it is mainly evaluated from five aspects: door sash, window sash, frame, lock and use, and it mainly remembers several standard values:
(1) Joint gap should be less than or equal to 1mm.
(2) The allowable deviation of the verticality of the front and side of the door and window frame is 2.5mm.
(3) The horizontal allowable deviation of the horizontal frame of windows and doors is 2mm.
(4) The allowable deviation of the horizontal frame elevation of windows and doors is 5mm.
(5) The allowable deviation of vertical deviation from the center of windows and doors is 5mm.
The strength of the profile is not enough.
The strength grade of aluminum alloy is divided according to the indexes such as tension, yield, hardness and so on.
The strength is not strong enough to be prone to deformation and damage in severe weather such as typhoon, which is a great threat to the safety of users’ lives and property.
Generally speaking, consumers can observe with the naked eye, press with hands, shake and other methods, basically can identify whether the strength of door and window materials is enough.
Poor quality of accessories.
Accessories as an important part of the safety of doors and windows, good hardware accessories are standard for good doors and windows, and good hardware accessories are more expensive.
In the actual real estate development, many developers generally use relatively cheap hardware accessories in order to reduce the cost of doors and windows.
Hardware accessories feel poor, not to mention poor quality, easy to rust, easy to break, resulting in falling fan injury and other safety accidents occur from time to time.
Poor performance of doors and windows.
The basic functions of doors and windows are ventilation, lighting and rain protection, which is the most fundamental concept of door and window design at present, but due to environmental reasons, more people will upgrade their requirements for doors and windows, such as heat insulation and mute, and then upgrade to overall beauty and permanent deformation.
Good doors and windows make your living environment more safe and beautiful, make you feel happy, better reflect your pursuit of quality of life, and promote your interpersonal circle.
For owners who pursue high quality of life, good doors and windows are the basic configuration of a comfortable living environment.
When your windows and doors are old, do you want to replace them directly or continue to use them?
What on earth can old aluminum windows and doors do?
- Renovation of aluminum windows and doors.
The methods commonly used in the renovation of aluminum alloy windows and doors are as follows:
1) No. 600 sandpaper is polished with soap water, and then self-sprayed varnish is used.
2) Angle grinder with steel wire wheel (fine wire) electric removal.
3) it is time-consuming and laborious to scrub with vinegar. - Aluminum windows and doors decoration.
If the old aluminum windows and doors cannot be reused, they can be used to decorate the room, which is also a way of waste utilization.
So the old aluminum windows and doors are not useless, as long as we find them attentively, we can maximize their value.
]]>
The aluminum window in the balcony position is generally drenched in the sun and rain, of course, it is very easy to oxidize and fade, but if you choose a good spraying process, the chance of fading will be very small.
Generally speaking, the quality of aluminum windows and doors is much better than that of plastic steel windows and doors.
The fading of plastic steel is inevitable, the material of plastic steel itself is good, but it is necessary to fade for a long time, to aging, this can not be prevented.
Therefore, compared with the windows and doors of all kinds of materials, the technology of broken bridge aluminum windows and doors is better.
Broken bridge aluminum windows and doors are used normally, and properly maintained, broken bridge aluminum profiles will not fade and change color!
Try to use the original factory broken bridge aluminum windows and doors products, not secondary spraying self-wearing products, those who can allow customers to choose the color of profiles are mostly secondary spraying self-wearing products, the product quality can not be compared with the original products.
The appearance color of broken bridge aluminum windows and doors should be bluish white.
The color is too white or gray, indicating that the stable ingredients in the material are not enough, and it is easy to age and turn yellow over time.
]]>What is the advantage of Aluminium window?
1, Heat Insulation Performance:
Its performance is quite good, if the installation is this kind of Windows and doors, then in the summer, the temperature of the house must be lower than the outside of the house, living up is also more comfortable. And in the winter, it stops the heat from escaping.
2, Waterproof Performance:
Because of its pressure balance, and in the production, the slope control is also better, so do not have to worry about water will accumulate in, the speed of drainage is certainly very fast.
3, Safety Performance:
The anti-theft performance of this kind of Windows and doors is very good, there is no way to open it outside, it can only be opened in the house, at the time of purchase, you can do a test, so that we also understand. Because of this, it has also been favored by many consumers, and it is very reassuring to use.
4, Anti-noise Performance:
Its structure is relatively complete, and it is also specially designed, so the sealing is quite good, as long as the window is closed, basically can not hear the noise outside. If the surrounding environment is noisy, this window is recommended as the first purchase.

Wood-aluminum doors and windows are very popular nowadays, compared with other doors and windows, aluminum windows and doors can be described as the “aristocracy” of doors and windows.
So, what is the difference between wooden aluminum doors and windows and other doors and windows?
Why are you so “aristocratic”?
1.Energy-saving type (thermal insulation).
There is a professional term in the world of doors and windows: heat transfer coefficient K value (also known as conductivity coefficient or insulation coefficient).
It is the most professional technical parameter to measure the thermal insulation of doors and windows. compared with other types of windows, aluminum doors and windows have outstanding thermal insulation performance.
Therefore, aluminum doors and windows are more energy-saving.
Therefore, although the price is slightly higher at the time of purchase, in the long run, using aluminum doors and windows can save you heating bills in winter and air-conditioning electricity bills in summer.
After such careful accounting, do you still think the price of aluminum doors and windows is expensive?
Cymbals.
2.Soundproof privacy.
Aluminum doors and windows can better block the external noise, and the sound insulation performance is better than other types of doors and windows.
- Fireproof performance.
In case of fire, the transmission of high temperature is slow, and the speed of fire transmission is slower, and doors and windows are not easy to cause a bigger fire due to high temperature explosion. - Long service life.
Doors and windows are not fast-moving consumer goods, so the service life of doors and windows is required to support the existence of the family.
Other types of windows, after long-term use, hinge, handle rust, a great impact on beauty and daily use.
