Today we will talk about how the finished product is inspected.
When a batch of finished Cutting wheels arrive at the packaging department, we have professional inspectors to do the appearance inspection. Yes, we have to inspect each piece. First, check whether the edges are neat and whether there are burrs, The second is to check the aesthetics of the layout. the 2th step is to check the static balance, and the balance is also the basic standard of the Cutting wheel; the third step is the cutting test, which is the most critical step and the most important test for the quality of the Cutting wheel. Each batch of our The goods must be randomly checked for the cutting performance of a fixed proportion, and each piece of Cutting wheel is responsible for it.

Cutting blade is a product often used in life, which is very helpful to industrial production and construction. It has high tensile strength, impact resistance and bending strength. How can we distinguish the quality of Cutting wheel blade when we buy it?
1. Check the nameplate and manual of the Cutting wheel cutting blade. The nameplate parameters shall be consistent with those on the 3C certificate.
2. Observe the outer package of the Cutting wheel cutting piece. The outer package should have a clear pattern without damage. Open the package box and observe the appearance of the Cutting wheel cutting piece. The color should be uniform. The surface of the plastic part should be free of obvious shadows, dents, scratches or bumps. The aluminum casting coating should be smooth and beautiful without damage. The surface of the whole machine should be free of oil stains and stains.
3. Hold the Cutting wheel cutting blade by hand, switch on the power, operate the switch frequently by hand to make the tool start frequently, and observe whether the on-off function of the stone cutting machine switch is reliable.
4. During the trial operation of the Cutting wheel cutting blade, observe whether there is any abnormality in the on-site television and fluorescent lamp, so as to confirm whether the tool is equipped with a radio interference suppressor.
5. During the trial operation of the Cutting wheel cutting blade, observe the reversing spark. The reversing spark should not exceed 3/2 level. Generally, when looking in from the air inlet of the tool, there should be no obvious arc light on the surface of the commutator, and there should be no abnormal noise during operation.
When it comes to the quality of machinery and accessories, “Made in Germany” is almost synonymous with top technology and quality. But with the continuous progress of science and technology, the industrial society is also developing faster and faster. The domestic production quality has also come from behind. Such as metal cutting pieces, such as stone cutting pieces, such as resin Cutting wheel pieces. What are the quality standards and inspection items of abrasive products? Now let’s share with you the Damon Cutting wheel!
External standards: the quality standards of abrasive tools include basic standards and technical standards. Basic standards include terms, symbols, codes, etc. Technical standards include technical regulations and inspection methods in terms of dimension tolerance, form and position tolerance, appearance defects, static balance, strength, hardness of abrasive tools, as well as safety rules for abrasive tools, marking and packaging of abrasive tools, acceptance and storage of abrasive tools, etc.
Internal standard: the inspection items of ordinary abrasive bonded abrasives include: appearance defect, overall dimension, geometric tolerance, hardness, static balance, rotary strength and organization number. These items directly affect the use of Cutting wheel cutting pieces, among which hardness, static balance, rotary strength and organization number directly determine the safety, use performance and other internal performance of the abrasive tools.
The above is the sharing of quality standards and inspection items of grinding tools by Damon Cutting wheel Group. Only through specified manufacturing and production and a series of inspections can the quality of cutting pieces be guaranteed. Damon Cutting wheel is produced in strict accordance with the “7s” on-site standard, and the products have passed ISO9001 inspection, CE and MPA certification.
There are many kinds of Cutting wheels, and blockage is a very common phenomenon, which occurs no matter what kind of Cutting wheel. Reducing the blockage of resin Cutting wheel can help to save resources and provide utilization rate. Now Damon Cutting wheel Editor will share with you the common type of Cutting wheel clogging – attachment type;
Attachment type blockage belongs to the blockage phenomenon caused by the mechanical filling of abrasive chips in the gap of Cutting wheel.
1. Cause of air flow movement: The wear debris slides out along the front of the Cutting wheel, and several layers of wear debris are accumulated in the local area in front of the abrasive grain. Under the effect of high-speed rotation, an air flow vortex area is formed, and the air pressure in the vortex area is significantly reduced. Under the effect of negative pressure, some wear debris cling to the back of the abrasive grain, forming an attachment plug on the cutter surface behind the abrasive grain. Most of the attachments are ashes and particles.
2. Cause of magnetic field movement: In the grinding area, there will be charges arranged according to a certain rule during friction. Under the action of high temperature, it will become positive ions and electrons. There are neutral atoms and impurity dust in the electric field; Under the action of electric field, some wear debris will show polarity and attract each other, and the wear debris will be adsorbed on the surface of the Cutting wheel. Because the electric field strength is very small and the adsorption force is very weak, the wear debris is not secure, and it can be stably embedded between the gaps on the surface of the Cutting wheel.
The procedures used by different manufacturers in the production of products are different, so the products finally presented are very different. In the long-term work of resin Cutting wheel cutting blade manufacturers, some problems are easy to occur on the surface, which will lead to the performance and advantages of resin cutting blade itself. For example, there are scratches on the surface of the resin cutting sheet. What is the cause? How should it be solved? Let’s analyze Damon Cutting wheel:
1. The resin cutting blade is too soft. The solution is to select a hard resin cutting blade.
2. The resin cutting blade is too thick. The solution is to choose a hard resin cutting piece or slow down the finishing speed of the resin cutting piece.
3. The coolant is not clean. The solution is to clean the cooling bath or replace the coolant.
4. Fix the problem. The solution is to check the finishing equipment in time.
The above is the solution to the cause of scratches. For more knowledge about cutting blades, please pay attention to Damon Cutting wheel. Damon Cutting wheel covers an area of more than 20000 square meters, with 13000 square meters of modern constant, constant temperature and wet workshops, 24 fully automatic production lines, a daily output of 250000 pieces, and 30-40 hours of finished products, with guaranteed delivery.
In the industrial production industry, machining products must be used to obtain cutting pieces. The cutting blade is widely used for cutting ordinary steel, stainless steel metal and non-metallic materials with high tensile, impact and bending strength. However, the cutting blade needs to be hardened in the production process. Why does the Cutting wheel cutting blade need to be hardened? Now, let’s share with you a little compilation of Damon Cutting wheel.
The step after mixing, awakening and molding is hardening. Hardening refers to putting the formed resin cutting sheet into the oven and firing it at high temperature. A cutting piece with fixed shape and certain hardness, strength and heat resistance. This heat treatment process is called hardening.
Angle grinder, also known as grinder or disc grinder, is a kind of abrasive tool used for cutting and polishing glass fiber reinforced plastics. The specifications of common angle grinder blades are divided into 100mm (4 inches), 125mm (5 inches), 150mm (6 inches), 180mm (7 inches) and 230mm (9 inches). The small size angle grinder used in Europe and America is 115mm. The common market vendors are divided into black and green. Is it better to be black or green? Damon Cutting wheel has 20 years of experience in producing Cutting wheel blades and cutting blades. Let’s share the differences between them:
Black pieces are generally brown corundum pieces. The cutting durability will be better, but the cutting effect cannot be guaranteed; Commonly used for cutting metal products such as iron pieces;
The green chip is generally made of silicon carbide. The characteristics of silicon carbide are relatively sharp, good cutting force, and ideal cutting effect, but the wear resistance is slightly lower. Mainly for stainless steel cutting.
There are also red cutting pieces on the market, which have thermal conductivity and are often used to cut nonferrous metals. It is not easy to damage the color of the cutting objects.
Many years ago, when Mr. Yang, a repairman in Haikou, started the cutting machine, the cutting blade suddenly broke into pieces and injured his eyes, eventually losing his sight. This is a big loss for Mr. Yang, and the manufacturer of the Cutting wheel cutting blade should pay compensation to Mr. Yang. Then why does the fracture occur and what causes it? Let’s share with you the following Damon Cutting wheel:
1. When the tissue of the cutting piece is uneven, with the torque, thermal stress, vibration and other factors in the cutting process, the stress will accumulate in the weak tissue, leading to fracture.
2. When the flatness of the cutting blade is poor, the cutting surface is arc-shaped. With the increase of the cutting depth, the cutting blade is subjected to increased lateral stress, which will cause cracks in the Cutting wheel blade and lead to “film” when it is used repeatedly.
3. When the hardness of the cutting piece is on the high side, the radial torque force on the cutting piece will increase. Because the thickness of the cutting piece is usually less than 4mm, the cutting piece will break.
Damon Cutting wheel has been producing cutting pieces for more than 20 years, strictly implementing the international environmental protection quality management certification, and has won the 2000 international quality system certification, MPA certification products and PICC quality insurance certification. Each process is strictly controlled and inspected by relevant QC.
The resin cutting blade is made of resin as the binder, glass fiber mesh as the tendon, combined with a variety of materials, and has a particularly remarkable cutting performance for alloy steel, stainless steel and other difficult cutting materials. At the same time, the choice of cutting material and hardness can greatly improve your cutting efficiency and save your production costs. What common quality problems will be encountered in the production of cutting pieces? Now Damon Cutting wheel will give you a technical analysis;
1. There are loopholes in the processing link
Cutting blade manufacturing is an industrial product with strong processability. If there are quality problems, you can find problems in mixing, forming, hardening, processing and other processes. High quality cutting pieces must be free of problems in every link.
2. Quality of purchased raw materials
Even if there are materials in production, but the quality is not good, it is impossible to make good products. Good raw materials are the premise guarantee for producing high-quality products. The abrasive quality is uneven and the binder particles are too coarse, which will affect the hardness and strength of the Cutting wheel.
3. Problems in production inspection
Raw material inspection, process inspection and ex factory inspection are important contents for resin bonded Cutting wheel manufacturers to implement effective inspection and control, but few manufacturers truly achieve standardized management and standardized management. The main problems include incomplete system, unfulfilled functions, lax management, out of control shortage of inspection equipment, poor professional quality of inspectors, etc.
4. Problems with production inspection equipment
The enterprise is not equipped with complete equipment, lacks a good mixer, and the tonnage specification of the hydraulic press is too small. At the same time, poor equipment maintenance makes it difficult to ensure the product quality.
