      The most easily damaged in the cutting blade to the sander is the brush. When it wears, its resistance will become larger and the electric spark will become larger, which will cause damage to the rotor. In the long run, the stator will also be destroyed, so it should be checked regularly to replace it. . The replaced brush should be consistent with the previous one, otherwise it will accelerate the self-wearing. The most important thing is to match the size of the brush holder and to be tight. If it is tight, the brush is ground up. The reason is that the brush or heat is generated during work, and the heat is swollen and contracted. After the expansion, it is easy for the seat to be stuck, because the brush and the reversing piece cannot be in good contact. , thus burning the rotor.

    • yanghm has written a new blog article "What is the production process of super thin 115 cutting disc ?" 11.06.2018

      The production process of super thin super thin 115 cutting disc bond grinding wheel is mainly cold pressing process. How about?
      Cold pressing process: The bonding agent used in the cold pressing process is a wetting agent and a powdery resin. The liquid phenolic resin, furfural, decyl alcohol, cresol and the like are usually used as a wetting agent, and the most used liquid phenolic resin. The factors determining the proportion of liquid resin and powdered resin are: abrasive particle size distribution, filler type, filler amount, viscosity of liquid resin, properties of powdered resin, and the like. If the viscosity of the liquid resin is larger, more liquid resin is required to completely cover the surface of the abrasive; the smaller the particle size of the abrasive and the filler, the larger the specific surface area and the more the liquid is used; the molecular weight of the powdered resin is higher. The lower the high and free phenol, the worse the adhesion to the liquid resin and the greater the amount of liquid required. In all of the above cases, it is necessary to increase the liquid to powder ratio. Generally, a liquid resin is used as a wetting agent, and the ratio of liquid to powder is 1:2 - 1:4, and a mixture of furfural or decyl alcohol and eucalyptus oil is used as a wetting agent, and the ratio of liquid to liquid is 1:6 - 1:8. The mixer is process-proven to achieve the desired mixing and does not damage the abrasive. The mixing time after adding the fine powder is generally 2-4 minutes. If the mixing is too short, the mixing is not uniform, the resin film is too long to fall off, and the temperature of the material is raised, and the resin is pre-cured.
      From the analysis of the aurora abrasives, the cold pressing process in the production process of the cutting blades is the most commonly used production process. Whether it is an super thin 115 cutting disc or other cutting pieces, this process is very critical, therefore, the majority of production In the process of production, manufacturers must grasp the various processes of cold pressing in the production process to prevent large quality problems due to a small mistake.

    • yanghm has written a new blog article "Process characteristics of free sample cutting disc grinding?" 11.05.2018

      The free sample cutting disc
      is the type of cutting disc that is commonly used by users nowadays. The grinding disc in the cutting disc is an important part of it. What are the technological characteristics of the grinding disc grinding process?
      1. High precision grinding
      Grinding is performed by the edge of the abrasive grain on the grinding wheel. The sharp edge of the abrasive grain can be used for micro-feeding. Therefore, a very thin layer of metal can be cut. Grinding tolerances are up to IT6 and the surface roughness is 0.8-0.1μm. For high-precision grinding, the tolerance class can reach IT5, and the surface ancestor value Ra is 0.1-0.006. Therefore, grinding is generally used as a finishing process for parts.
      2. Can process high hardness materials
      Due to the high hardness of the grinding wheel, in addition to the general material, it is also possible to process materials that are difficult to machine with conventional tools, such as hard gold or hardened workpieces.
      3. High grinding temperature
      The speed during grinding is very high. Generally, the cutting heat generated by 30-50m/s is large, the thermal conductivity of the grinding wheel is poor, and the instantaneous broaching temperature in the grinding zone can reach 1000 °C. High temperatures can cause deformation, burns, or mechanical degradation of the workpiece. In order to reduce the influence of high temperature on the processing quality, a large amount of cutting fluid is used during grinding. When grinding steel, the widely used cutting fluid is soda or emulsion.

    • yanghm has written a new blog article "Precautions for storage and use of green cutting disc?" 11.03.2018

      When the user uses the green cutting disc , it is the same as other cutting pieces such as 115 * 1 * 22 cutting disc . In order to use the product for a longer period of time, pay attention to some precautions for use. The precautions for storage and use of the green cutting disc are as follows:
      1. Care must be taken when handling the cutting piece to prevent collision and cracking!
      2. When the cutting piece is stored, it should be moisture-proof, anti-freeze and anti-deformation. The cutting piece should be mounted on the wooden pallet or wooden frame. The stacking height should not exceed 1.5 meters!
      3. The storage time of the green cutting piece is one year. If the time exceeds the time, the rotation test should be carried out again.
      4. When the cutting piece is installed on the angle grinder, the flange surface that is in contact with the cutting piece is required to be clean and flat. When tightening the cutting piece, it is required to be tightly elastic. Only special wrench reinforcement is allowed. It is forbidden to use supplementary jig (such as lengthening wrench). To prevent human damage to the abrasive tools!
      5. The cutting speed of the cutting piece should not exceed the working line speed specified by the trademark of the cutting piece. When using the pneumatic grinding machine, it is necessary to prevent the air pressure from being unstable, resulting in the cutting piece exceeding the speed!
      6. When using the cutting piece, it is necessary to make a sudden force. If the force is too strong, it will easily stop, jam and crush the cutting piece. If it is stuck, the cutting piece should be lifted immediately to avoid the burning piece or the broken piece!
      7. The cutting piece can only be used for single piece installation. It is strictly forbidden to install two or more pieces at the same time!
      8, the cutting piece is only allowed for cutting, not allowed for grinding!
      9. The equipment used for cutting sheets should meet the safety regulations of GB4674 grinding machinery!
      10, the user is using the cutting piece should comply with the GB2494 abrasive safety rules!

    • yanghm has written a new blog article "What are the steps for mirror polishing of a free sample cutting disc?" 11.02.2018

      Now that the cutting piece is polished after a period of use, if the
      free sample cutting disc
      needs to be mirror polished, then you need to follow the steps below:
      (manual) 600 → 800 → 1000 → 1200 → 1500 (grinding machine) → 2000 → 2500 → 4000 → polishing cloth (6Micron) → polishing cloth (3Micron) → polishing cloth number is not mistaken, it means that there is between every 1 inch How many particles, the larger the finer the particles.
      After 1200, only water is added. There is no special effect. The particle size of 1200 mesh is 21Micron. Generally, the particles of the slurry are decremented from 25Micron. Therefore, the effect of the slurry (polishing paste) will come out. If only water is added, it will be ground. It is OK to 1000 or 1200.
      The grinding machine has the best effect and the fastest, and can be polished to more than 2000 mesh to become a very bright mirror, which is difficult to achieve by manpower. Finally, it can be polished into a bronze mirror with a polishing cloth.
      The expensive sandpaper is highly durable and will not crack if it is curled.
      Buying one piece of coarse sandpaper is OK. Fine sandpaper (600 or more) can buy 2~3 sheets depending on the situation. The thick one is more wear-resistant, so one can be worn for a long time, but the fine one will be consumed quickly. One thing to note is that too fine sandpaper (more than 1000) should try not to touch the surface, because the hand will also consume sandpaper.
      Because of the various materials and quick results, the polishing paste particles are not very fine. It is fine to grind a special abrasive (but it takes a long time to grind). The benefits are ease of use and low flow (paste), especially for curved surfaces or irregular surfaces. Some polishing pastes have a reducing agent to rust the rusted surface or add a rust inhibitor. It can be rust-proof, which is not possible with pure abrasives.

    • yanghm has written a new blog article "How to use green cutting disc?" 10.31.2018

      green cutting disc have a lot of skills when they are used. These techniques can help us make better use of cutting pieces. Let's introduce the techniques of cutting slices.
      1. Idling: When the special new substrate is used for the first time, it needs to be idle for about 30 minutes. In summer, the high temperature season needs to be idling with water. The purpose is to further eliminate the influence on the substrate when welding the cutter head and enhance the saw blade at high speed. Stick to the inner quality of memories.
      2, the block material should not be less than 0.5m3, and placed insurance, the bottom should be padded with square wood, the plug is solid, the block should be located in the symmetrical orientation of the workbench to ensure the stability of the work trolley and block, no shaking Thriller.
      3, the use of cutting piece slicing skills, according to the length, width, height of the block to adjust the travel switch, so that the blade lift and the trip of the skip is in a useful range. Before sawing, the blade edge should be 10~20mm away from the original material. After sawing, the sawhole should be 20-40mm away from the bottom of the block. Before the saw blade moves left and right, the saw blade should be completely removed from the block sawing, and the interval should not be less than 150-200mm to avoid the saw blade crash. material.
      4. After the slice is idling and stable, the test can be cut open. When the saw blade edge and the block material are touched, the saw blade is activated. When the cut is cut, the saw blade is stopped and the saw blade can be stopped after exiting the saw.
      5. If the blockage is found to be swaying when cutting, the cut should be stopped immediately. After the blockage is fixed firmly, it can be continuously operated, cut open, and the barn is prohibited.
      6. When cutting, it is found that the saw blade has a significant deceleration or even a knife clamping phenomenon, which may be caused by the belt slipping, the loosening of the compression nut or the depth of the knife, and the speed of the knife being too fast.
