The so-called CNC saw is CNC fixed-length, that is, when the movable head moves, it is numerically controlled. This is the main difference. When the ordinary double-head saw is fixed to length, it is manually operated, and the movable head is pushed to the required size position, and then After fine-tuning to the required size, lock the movable machine head. As for the length cutting accuracy, the CNC error is within 0.2 mm, and the length cutting error of the ordinary double-headed saw is within 0.15 mm. The real mass production must be the ordinary double-headed saw. Easy to use, high precision, low failure, simple and practical operation.

The function of automatic swing angle is also available in ordinary saws. The electromagnetic reversing valve is controlled by the switch, and after ventilation, it is converted into pneumatic operation of the cylinder to realize the angle conversion.

The sawing is driven by the cylinder, and the spray is also automatically sprayed with the sawing action.

The CNC saw is mainly the function of CNC automatic sizing. As for the accuracy, the ordinary CNC is similar.

Intelligent manufacturing is a hot spot in the industry. Under the trend of intelligent manufacturing, CNC system is the core technology for the transformation and upgrading of the manufacturing industry. From a certain perspective, the future development of intelligent manufacturing is inseparable from the breakthrough of CNC system and key technologies.
CNC machine tools are increasingly emphasizing intelligence and digitization. It can be seen that the future development trend of CNC machine tools is intelligent equipment.

Intelligent manufacturing provides a historic opportunity for the leap-forward development of China’s manufacturing industry. The new generation of intelligent manufacturing technology formed by the deep integration of a new generation of artificial intelligence technology and advanced manufacturing technology has become the core driving force of the new round of industrial revolution.

The road to change from “CNC” to “Intelligent” machine tool industry is not only technological development, but also the natural requirement of the general trend is also the industry’s inevitable response to the high-quality development of the former economy.

The intelligent equipment production line consists of four parts: frame and fan material production line, middle stile production line, double-headed corner group production line, and logistics line. The fully automatic aluminum alloy door and window intelligent production line makes the production process intelligent, with high precision and programmed material transfer.

The future development is not static. The research and development of intelligent door and window equipment also needs to keep up with the development and needs of the society. JMD pace has always been ahead, leading the trend of development!

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

1. 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.
2. 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

1. 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).
2. 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.
3. 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 improvement of people’s living standards, there are higher requirements for the materials and quality of home improvement. After a busy day at work, I think of a home where we can relax and feel comfortable. That is the “safe haven” of our life. For the windows and doors of home improvement, literally, aluminum-clad wood should be made of aluminum outside and wood inside, forming aluminum material wrapped with solid wood; while wood-clad aluminum should be wood outside, aluminum inside, and solid wood wrapped with aluminum material. So what is the difference between aluminum clad wood and wood clad aluminum? Does it really mean this literally? Of course not all, then let me take you to market analysis and analysis together!

Let’s take a look at the profiles of aluminum-clad wooden windows! Aluminum clad wood belongs to the structure composed of aluminum material on the outside and pure solid wood on the inside. The proportion (section) of solid wood is more; The solid wood and the aluminum alloy plate are generally connected and “clad” through the “buckle” process. (Sure enough, as the editor guessed, is the wood-clad aluminum the same?)

The profile of the wood-clad aluminum window has a lot of origin from the literal meaning. Of course, the wood-clad aluminum windows and doors are of the outer aluminum + inner wood structure. However, at this time, the inner wood is only about 15mm thick. The solid wood is made of solid wood, and the outside of the solid wood is wrapped by “broken bridge aluminum” made of high-strength nylon heat insulation strips, and between this broken bridge aluminum and solid wood, it is glued and “aluminum ‘buckle’ wood”. way wrapped together.

Now, do you understand the general difference between aluminum-clad wood and wood-clad aluminum, as I do? ! In short: aluminum-clad wood: more wood and less aluminum; wood-clad aluminum: less wood and more aluminum. But no matter how “snapped” and glued, the material of aluminum must be on the outside, you can see it clearly.

The reason why aluminum alloy doors and windows occupy the largest market share is that in the vast cities and towns of my country, aluminum alloy doors and windows have been developed for a long time and a wide range. At the same time, through the development of recent years, aluminum alloy doors and windows have solved the problems in the early stages of development. Such problems are more and more favored by customers for its corrosion resistance, high strength, light weight, and good decorative performance. So what are aluminum alloy doors and windows and how are they defined?

Doors and windows made of aluminum alloy extruded profiles as frames, stiles, and fan materials are called aluminum alloy doors and windows, or aluminum doors and windows for short. Including aluminum-wood composite doors and windows that use aluminum alloy as the base material of the load-bearing rod (the rod that bears and transfers its own weight and load) and wood and plastic, referred to as aluminum-wood composite doors and windows. The quality of aluminum alloy doors and windows can be roughly judged from the selection of raw materials (aluminum profiles), aluminum surface treatment and internal processing quality, and the price of aluminum alloy doors and windows.

1. Materials
   The thickness, strength, and oxide film of aluminum profiles used for high-quality aluminum alloy doors and windows should comply with relevant national standards. The wall thickness should be 1.2 mm or more, the tensile strength should reach 157 Newtons per square meter, and the yield strength should reach per square meter. 108 Newtons per square millimeter, the thickness of the oxide film should reach 10 microns. If the above standards are not met, the doors and windows of inferior aluminum alloy cannot be used.

2. Processing
   High-quality aluminum alloy doors and windows, fine processing, careful installation, good sealing performance, and easy opening and closing. Inferior aluminum alloy doors and windows, blindly select aluminum profile series and specifications, processing indiscriminately, using sawing instead of milling, not installing as required, poor sealing performance, uncomfortable opening and closing, not only leakage of wind and rain, glass explosion, but also In strong winds and external forces, it is easy to scrape or knock the sliding parts or glass off, destroying objects and injuring people.

3. Price
   In general, due to the high production cost of high-quality aluminum alloy doors and windows, the price is more than 30% higher than that of inferior aluminum alloy doors and windows. Some aluminum alloy doors and windows made of aluminum profiles with a wall thickness of only 0.6-0.8 mm have a tensile strength and yield strength that are much lower than the relevant national standards and are very unsafe to use. In addition, there are many self-employed people who process aluminum alloy doors and windows, and they do not understand the structural characteristics and performance of aluminum alloy doors and windows. In order to reduce the cost and cut corners and shoddy materials, the product has a greater hidden danger and is generally not suitable for use. It is best to choose products from regular aluminum alloy doors and windows manufacturers. Here is a special note: the current national standard profile thickness is 1.4mm, if the supplier chooses 1.2mm or 1.0mm wall thickness or even thinner materials, they are all substandard products, please buy Attention.

Aluminum alloy is the most economical and reasonable for building structure. the higher the purity of aluminum is, the lower the strength is, so scientists added other elements to aluminum and invented aluminum alloy to enhance its physical and mechanical properties.
Aluminum is rustproof, with a good appearance, and the life of aluminum alloy is the longest.

However, aluminum alloy must also be carefully selected, choose a brand of good quality, and there is also a guarantee after sale.
If it is a mixed brand, they will add different amounts of waste aluminum at the time of production to offset some pure aluminum ingots, so that the whole cost price will be lower, but the quality can be imagined.

Home decoration is a day to cut flowers for thousands of days to see, it is necessary to pay more attention to research.
Quality is very important, do not let yourself spend hundreds of thousands of new houses to install defective doors and windows just because they are hundreds of yuan cheaper.
