Changsha Langfeng Coating Materials Technology

Posted on: 四月 28th, 2016 by langfeng No Comments
In addition to constantly develop new tool models, cutting tool coating technology is still new and has made progress in the field of materials, which will help reduce manufacturing costs. Gear milling Sandvik is constantly developing optimized material.
“For Seco Tools, the coating is one of the major investment, Duratomic coating is one of the products of our most rewarding. Duratomic coatings have changed the pattern of the market, the development of this product has far-reaching significance, “Manta added.
“Coating technology continues to progress, it seems that will not stand still for decades. The most interesting technology is to improve the adhesion of the coating by the introduction of new PVD technology,” Witte said.
Ingersoll Berardi said: “Since we are using the coating has been PVD (physical vapor deposition) process of oxidation protection layer abrasive wear resistance, heat resistance and chemical resistance and high temperature CVD coating (chemical vapor deposition) process is similar, by using a low-temperature PVD treatment, so that the blade higher toughness, wear better. Further, before and after surface treatment coating significantly improved the performance of the tool. either by improving coating the adhesive layer, reducing the crack source location, to reduce friction, or by making the surface smoother workpiece, different ways of surface treatment contributes a lot to improve production efficiency. “

Microwave sintering technology advantages

Posted on: 四月 22nd, 2016 by langfeng No Comments

Microwave Vacuum Sintering Furnace

1. The sintering temperature is significantly reduced, as compared with the conventional sintering, the maximum cooling rate of up to about 500 ℃.

2. Energy efficiency than conventional sintering 70% to 90%, lower sintering energy costs. Because microwave sintering time is greatly reduced, especially for some ceramic sintering process from the last few days or even weeks to reduce the use of microwave sintering of a few hours or even a few minutes, much too high energy efficiency.

3. Security pollution. Rapid sintering characteristics of microwave sintering makes during sintering as a sintering atmosphere of gases is greatly reduced, which not only reduces costs, but also to the sintering process waste gas, waste heat emissions are reduced.

4. Use the microwave method for rapid heating and densification can inhibit tissue grow grain, thereby preparing nano-powders, ultrafine or nano-bulk materials.

5. Sintering time is reduced compared to conventional radiant heating densification process accelerated, both inside and outside at the same time the material is uniformly heated so that the thermal stress within the material can be reduced to a minimum. Secondly, under the action of microwave electromagnetic energy, molecules or ions within the material kinetic energy increases, the sintering activation energy decreases, the diffusion coefficient is increased, it can be low-temperature fast sintering, so no time to grow up to be sintered powder.

6. Achieving spatially selective sintering.

Microwave Vacuum Sintering Furnace

1, before the operation to put on work clothes, work shoes, wear gloves and a dust mask.

2, open the oven to prepare:

2.1 Recognizing the system is normal, water, electricity is smooth, no leaks. Check the interface, door, valves and other seal is good, whether the need to replace dirty oil pump, oil level is appropriate, the vacuum pump is functioning properly and so on;

2.2 should be installed to prevent the boat to break something corundum furnace tube, and can not occur in contact with the carbon rod to determine the suitability of the location of the boat.

3, should be strictly enforced in accordance with the process requirements heating program. When you first open the main valve to start the electrical cabinet, then close the pump power, turn on the main circuit switching power supply, when the vacuum degree to meet the requirements, according to the “RUN” button to start the program.

4, can only open the Roots vacuum furnace to determine the size of the vacuum degree requirements in line with Roots vacuum pump (600pa) time.

5, when the use of wheat vacuum gauge reads vacuum of the furnace should be slowly turning wheat vacuum gauge, in strict accordance with operational requirements, as the reading level.

6, the heating process should pay attention to monitor various parts of the furnace cooling water changes, abnormal timely manner.

7, when the shutdown in reverse order, press the “RST” button to end the program, and then disconnect the main circuit switch and disconnect the power vacuum, and finally total disconnect electrical cabinet valve.

8, when the electrical cabinet overcurrent, overvoltage alarm, immediately record the program operation, contact an electrician who repairs, while each of the main circuit disconnect switch, turn off the vacuum pipe valve, disconnect the pump power.

9, without water cooling phenomenon should immediately shutdown and record operating conditions of the program.

10, if a sudden power outage, you should immediately turn off the vacuum pipe value, record the health program, and disconnect the main circuit switching power supply and a vacuum pump.

11, to keep the environment clean and on-site equipment.

How to choose a diamond coated tools

Posted on: 四月 19th, 2016 by langfeng No Comments

tungsten carbide glass cutter wheel2

Like any other tool, stone chisel life vary, depending on the material being cut, the choice of the cutting speed and feed rate, and the geometric shape of the workpiece and the like. In general, the processing of graphite diamond-coated cutting tool life is 10-20 times uncoated carbide tools, possibly even longer in some cases.

This can be done with a tool almost any machining task due to tool wear and tool change without the need to avoid the disruption and re-calibration process, making it possible to achieve unattended processing. In the processing of composite materials, it is also entirely possible to get longer tool life.

Diamond coating spalling can prevent flaking of the coating is a serious problem of diamond coated tools, but also a common problem (especially when machining materials like carbon fiber), will lead to unpredictable tool life. The late 1990s, the chemical properties of the interface is determined to be an important factor affecting the diamond coating adhesion properties. By choosing the good compatibility Carbide chemical properties, the use of appropriate pretreatment technology and reasonable deposition reaction conditions, it is possible to reduce or eliminate the diamond coating flaking stably smooth wear pattern. Under the microscope normal wear diamond coated tools can be found, the diamond was worn until stable carbide substrate, without the occurrence of chipping or peeling.

Microwave High Temperature Tube Furnace

Microwave and radio, infrared and visible light is electromagnetic waves, only the microwave is a kind of high frequency electromagnetic wave, the frequency range of 0.3 ~ 300 GHZ, wavelength of 1 mm ~ 1 m.

Microwave heating technology is dated from the second world war, when the United States is responsible for the maintenance of radar engineers often find chocolate will melt in the pocket, just realized that electromagnetic waves for material has the effect of heating, drying, thus raises the study of the technology.

Microwave sintering is a kind of new method of material sintering process, compared with the conventional sintering, it has the heating speed, high efficiency, high heating efficiency and safety and hygiene pollution-free characteristics, and can improve the uniformity of the product and yield, improve the microstructure and properties of sintered materials. In the 21st century, as people to the attention of the nano materials research, the technology in the preparation of nano block metal materials and nano ceramic has great potential, the technique is known as “the 21st century a new generation of sintering technology”.
