How to see the model of the grinding disc

2018-11-05 10:46:13 | 日記
The model of China high efficient grinding disc is different, and the representation is different. However, if we do not buy it, it will be easy to buy the wrong one. It will take time to exchange it, so we should understand China high efficient grinding disc model. The users, especially those who are frequently used, are as follows.

For example, if China high efficient grinding disc model is: SPA 400×100×
Representing the shape code, 400 represents the outer diameter D, 100 represents the thickness H, 127 represents the aperture D, A represents the abrasive, 60 represents the particle size, L represents the hardness, 5 represents the tissue number, B represents the binder, and 35 represents the high line speed. m/s.

For the above summary, the method of grinding the disc when viewing the model, different models may have different values, we can refer to the above list to understand what each item represents, so that you can buy China high efficient grinding disc you need, hope Can help everyone.

Precautions when using diamond grinding wheel

2018-11-03 11:17:10 | 日記
1, positive operation problems
  In daily use, many operators are always accustomed to working on a fast grinding wheel for stainless steel because the direction can be used. In fact, this behavior is a special prohibition in the operation of the grinder. According to the operating procedure, when grinding the workpiece with a grinder, the operator should stand on the side of the grinding wheel and must not operate on the front side of fast grinding wheel for stainless steel to avoid the grinding wheel flying out or the grinding wheel breaking out and injuring people when the grinding wheel fails.
2, side grinding problem
  In the daily use of diamond grinders, we often find that some operators do not divide the type of grinder, regardless of the type of grinding wheel, and use the side of the grinding wheel to grind at random. This is a serious violation of the safety operation rules. Operational behavior. According to the regulations, the fast grinding wheel for stainless steel with the circumferential surface as the working surface should not be grounded. The radial strength of the grinding wheel is large and the axial strength is very small. When the operator is too strong, the fast grinding wheel for stainless steel will be broken and even hurt. In practice, This behavior should be prohibited during use.
3, joint operation problems
  In the actual daily operation, there are also such situations. Some people share a grinder and operate at the same time in order to catch up with the production task and grab the working time. This is a serious illegal operation and should be strictly prohibited. When a grinder is not enough, it can be solved by adding a grinder. It is not allowed to share a grinder at the same time.
4, hard operation problems
  In the use of grinders, some operators, especially younger operators, are trying to grind quickly and use too much force, which is a very unsafe operation. The flatness of any grinding wheel has a certain strength, which is likely to cause the fast grinding wheel for stainless steel to break, or even fly out and hurt people, it is also a behavior that should be prohibited.

Grinding Wheel, How To Keep It?

1. The actual line speed of the high quality 9'' grinding wheel shall not exceed the requirements of the following table.
2. Before the installation of the grinding wheel, check the speed mark of the high quality 9'' grinding wheel, check whether there are cracks and damages, and check the strength.
3. After the installation of the grinding wheel, it must be idling for not less than 5 minutes with the protective cover. Only when it is sure that the grinding wheel has reliable strength can it start working.
4. It is forbidden to use a coolant that has a destructive effect on the high quality 9'' grinding wheel binder.
5. When handling the grinding wheel, it is necessary to prevent severe vibration and impact.
6, according to the size and shape of the high quality 9'' grinding wheel, should be placed on the shelf and in the box.
7. The grinding wheel should be stored to prevent moisture and freezing.
8. The storage period of the high quality 9'' grinding wheel shall not exceed one year. If it is overdue, it must be strictly checked to confirm that the quality is no problem before it can be used.

Abrasives in the field of ceramics

A nice China grinding disc manufacturer can not only provide a 4 inches China grinding disc factory price but also a high quality grinding disc. As a professional manufacturer, let us introduce Abrasives in the field of ceramics for you.
Which abrasive tools are used in the process of ceramic production and in the grinding process? Is the frequency of use frequent?

The answer is yes. Take ceramic tiles as an example. The specific application is as follows:

1. Brick embryo classification. There are many sizes of bricks, but one line can only be polished one size;
2. On the brick. Separate the pipeline by the machine;
3. Before trimming and chamfering, the size of the brick embryo will need to be a little larger, leaving some room for it. For 600*600, the size of the brick is 620*620. In this step, the depressed grinding disc for metal is used to carry out the dimensional specification, and the excess size is ground to the majority, and then the metal diamond chamfering disc is roughly chamfered, commonly known as pre-grinding;
4. Scrape flat. Generally, bricks have different degrees of uneven deformation, and the hob is used for smoothing. The hob is from 30#~170# coarse-grained, responsible for flattening the deformed bricks, and the fine grain size is responsible for gradually covering the front coarse grains to leave deeper knife marks, preparing for the next medium grinding;
5. Medium grinding. Use a metal diamond grinding block or a tangential depressed grinding disc for metal. This step is to completely erase the knife marks;
6. Fine grinding. Grinding blocks with silicon carbide, ranging in size from a few hundred to several thousand. Finish the corners after the silicon carbide finish. Finishing the corners with a resin or silicon carbide trimming disc or chamfering depressed grinding disc for metal;
7. After trimming and chamfering. The final size of the brick is fixed by a relatively thin metal diamond trimming disc, and then the resin trimming disc and the chamfering disc are used for fine grinding and chamfering;
8. Polishing. Polishing with a wool depressed grinding disc for metal or cloth disc plus some polishing paste;
9. Waxing. Waxing the rotating body with a wool brush or the like;
10. Detection. Rework for knife marks and chipping collapses;
11. Packaged into the warehouse.

Characteristics of sintered diamond grinding wheel

2018-10-31 15:40:07 | 日記
Because grinding wheel for stainless steel manufacturing process determines the surface morphology is random, the geometry, distribution and cutting edge of each abrasive grain are inconsistent. Therefore, only a few high cutting edges are cut to the workpiece during grinding, which limits the grinding quality and further improves the grinding efficiency. improve.

The sintered metal bond grinding wheel for stainless steel is mostly made of a metal such as bronze as a bonding agent and is manufactured by a high-temperature sintering method. The bonding strength is high, the formability is good, the high-temperature resistance, the thermal conductivity, and the wear resistance are good, the service life is long, and a large load can be withstood. Because the grinding process of the grinding wheel inevitably has shrinkage and deformation, the grinding wheel must be shaped before use, but the dressing of the grinding wheel for stainless steel is difficult. The conventional grinding wheel-rolling method is not only time-consuming and labor-intensive, but also the diamond particles fall off during the dressing process. The dressing wheel itself consumes a lot and the shaping precision is low.
