Wheel life and its end form
Any grinding wheel has its use of certain wear requirements, wear to a certain extent must be re-replaced with a new wheel. Not in order to save material, the requirements on the use of ultra-wear, which is a very unsafe illegal behavior.
Any grinding wheel has its use of certain wear requirements, wear to a certain extent must be re-replaced with a new wheel. Not in order to save material, the requirements on the use of ultra-wear, which is a very unsafe illegal behavior. General provisions, when the wheel wear to diameter 10mm larger than the chuck should be replaced when the new wheel.
The actual grinding time between grinding wheels is called grinding wheel life. Judging wheel life, generally based on the work surface after the phenomenon of wear and tear to determine the visual phenomenon. The main phenomena are: the process of self-excited grinding vibration, the surface of the workpiece surface regeneration pattern; grinding noise increases; the workpiece surface grinding burns, abrasive sharp increase or decrease; grinding accuracy; grinding surface Roughness increases. These phenomena are mainly due to the grinding temperature is too high to surface thermal damage and due to self-excited vibration caused by the roughness and accuracy decreased.
Grinding wheel end of the form: Grinding wheel surface passivation - grinding state (will increase the grinding force and grinding heat); wheel clogging (prone to vibration or noise to burns); grinding wheel contour damage (processing accuracy).
Any grinding wheel has a certain period of validity, in the validity period, it is qualified grinding wheel; more than the validity of use, not necessarily qualified grinding wheel. The regulation stipulates that "the grinding wheel should be used within the validity period, the resin and rubber bonded wheel must be rotated for one year after storage, and the qualified person can use it".

Grinding wheel dressing tools and dressing conditions have a significant impact on wheel dressing quality, not only affect the grinding wheel shape and sharpness of sharpening, but also affect the grinding wheel wear, grinding force, grinding temperature and the surface integrity of grinding parts . In the actual production, generally based on the accuracy of the workpiece requirements, the nature of the wheel, the workpiece material and processing methods to determine the dressing methods and dressing tools.
(1) diamond dressing. Diamond dressing is to diamond as a tool, that is, large pieces of diamond inlaid in a special diamond arbor, with the form of cutting to dress wheel method. Dressing wheel, the diamond knife mounted on the grinder in a special dresser, the vertical knife to carry out dressing. As the diamond hardness is very high, sharp edges and corners, grinding wheel can be trimmed correctly and meticulously, can obtain high processing precision and very fine surface roughness. Therefore, it is one of the most commonly used dressing methods.
With diamond dressing wheel should pay attention to the following matters:
① must be a reasonable choice of the size of diamond particles. Diamond size should be based on the size of the wheel to select, under normal circumstances, the wheel diameter of 100mm in the following, optional 0.25 karats of diamond. Diamond wheel diameter of 100mm or more, the election 0.1-1 carat diamond.
In order to make the dressing of the grinding wheel sharp and smooth, the tip of the diamond must be kept sharp, the tip of the study into 70 ° - 80 ° sharp angle.
③ Before and during installation, always check the diamond welding is strong and whether there are cracks, so as not to repair the loss of diamond.
④ diamond rod installed in the wheel dresser, the extension of the length to be short, clamping to be strong, so as to avoid jitter when dressing, affecting the quality of finishing.
⑤ Diamond and grinding wheel contact point should be lower than the wheel axis 1-2mm, diamond rod upward tilt 10 ° ~ 15 °, while horizontal axis tilted with the wheel 15 ° ~ 30 °, so that when turning the diamond grinding wheel negative Angle and the main angle, the turning effect is better. Diamond must not be mounted on the wheel axis above, otherwise, under the action of grinding force in the diamond tip will pierce the wheel, or in the dressing of the diamond vibration. If the installation is too low, the force is too small, affecting the dressing diamond play a sharp role. At the same time because of the installation angle exists, but also can keep sharp sharp corners of the diamond, such as a direction grind, and for a direction can be used, can improve the service life.
⑥ according to processing requirements to determine the amount of repair. Coarse grinding, grinding wheel surface roughness, this can increase the dressing of the depth of the knife and trim the lead. Fine grinding, on the other hand, the smaller the dressing dressing lead, grinding wheel surface repair more smooth, abrasive micro-blade, such as the higher the better. Fine finishing, the general infeed into the horizontal feed 2-3 times, and then in the case of no feeding for several repairs.
⑦ dressing should be fully cooled, do not allow intermittent pouring coolant, so as to avoid sudden and cold diamond abrasions, dry grinding dressing, the repair should be paused after a few times, so that the diamond can be cooled.
(2) diamond pen finishing. Diamond pen is a small particle by the diamond or diamond powder with a strong combination of the alloy together, pressed into the special made of metal arbor. According to the distribution of diamond, there are three types of diamond pen: layered diamond pen - diamond particles layered distribution; chain diamond pen - diamond particles into a chain distribution; powder diamond pen - diamond particles were irregularly distributed .
There are many factors that affect the dressing quality, such as the edge shape of the diamond, the wear resistance of the diamond, the dressing parameters (trim feed rate, wheel dressing speed, dressing depth), dresser, wheel characteristics Type, hardness, particle size, texture, binder) and grinding fluid.

The advantages of new temperature resin grinding wheel
The advantages of new temperature-resistant resin grinding wheel
The new temperature-resistant resin grinding wheel technology is
mainly applied to the following two types of grinding wheel: First,
large diameter resin cutting wheel; Second, heavy-duty resin grinding
wheel.
More than two major categories of resin grinding wheel is mainly used in modern steel enterprises. Large-diameter resin cutting wheel mainly used in steel production line profiles of iron and steel wire-length cutting; heavy-duty coarse resin grinding wheel is mainly used for steel ingot or rail and other materials, coarse grinding.
As the above two categories of grinding wheels often work under more stringent conditions, requiring such a wheel must have a high temperature performance, can withstand greater load, better grinding characteristics, grinding efficiency is better , Can work in a large line speed conditions, the balance of performance, and more durable. For heavy-duty coarse grinding resin grinding wheel must also have a greater density.

For heavy-duty coarse grinding resin grinding wheel must also have a greater density.
Basics: Wheel of water
After the grinding wheel is produced from the oven, it re-enters a water-filled environment until it is consumed. Wheel of life, is a constant face of water vapor life, but also a constant struggle with the water life. While the abrasive wheel manufacturers are deeply affected by the performance of the headache and it is closely related to attenuation. But in the end is how the matter?
Take a look at the structure of the wheel, see Figure 1.
In the production of the wheel mixer on the pot, our sand for the first time met its long-standing resin solution, began to be firmly wrapped live, their feelings can not be purely disturbed by any third party. In the pot mixer, the other filler, resin powder, active additives (please give this component with more attention) and dyes, where uniform mixing, and then wait on the pot prince and prince.
Once the pot of resin liquid and sand come, the composition of the pot will be evenly wrapped around them. On the pot can not add any other component, is that any other components in the pot on the join, will affect the uniform distribution of materials, resulting in potential stress for the grinding wheel after the distortion of foreshadowed. This is a principle that can not be broken. If the mixture is a problem, it should look for other solutions, the feeding sequence process or should stick to.
Resin solution on the sand package, there is no chemical bond, is a purely physical curing package. Therefore, if the sand can be properly treated with a coupling agent, some chemical bonding can be generated between the resin liquid and the sand, and the bonding strength thereof should be increased. Since the two are physical integration, the intensity is not high, as the fairy tale said, it is easy to get involved in a third party. In this article, this disgraceful third party is water.
To see how the invasion of the third party. Figure II.
Water slowly from the outside invasion, and gradually invade the wheel to the inside, but also invasion of resin liquid film and the gap between the sand. We give this water at different stages of a number: wheel outside the water is 1, the wheel structure within the water is 2, further resin liquid film and sand between the water is 3. You see, it really is a small three.
Water 1, free in the grinding wheel outside, in fact, the impact on the grinding wheel is negligible. Water 2, has entered into the wheel, grinding wheel gap, easy to come out easily, but as a channel, the negative impact is gradually increasing. Damage to the wheel is the largest water 3. Water 3 latent here, in the wheel storage process, it seems that do not see too much problem. But once the wheel starts to work, the water becomes hot water into a huge volume expansion, it's destructive power is very frightening. It will really like a demon, Cuikulaxiu-like resin film from the sand peeling off. Sand quickly fall off, large beads beads falling jade plate generally become a mess, the performance change is the wheel of attenuation. Especially for the ultra-thin, this problem is particularly serious. This damage, but also to the internal wheel of the stress released, resulting in distortion, which is the wheel's warpage. Of course, there are other reasons for grinding wheel warping, such as mixing, such as trapped material, such as oven control, but not discussed in this column.
So to solve this type of problem of the program, it is important how to deal with these three water.
Water 1 treatment, mainly packaging and transportation, should be avoided as much as possible the external environment of water vapor intrusion. Many high-end grinding wheel, all plastic packaging, the reason lies in this.
Water 2 treatment, it is relatively complex.
Specific possible options are:
1, increase the wheel compactness, reduce the gap, to reduce the wheel of the invasion;
2, hot pressing wheel production, need to pay attention to molding;
3, control the use of absorbent materials;
4, select the appropriate resin powder and resin solution to close the possible water vapor intrusion channel;
5, adjust the curing process to close the possible water vapor intrusion channel;
Vapor damage to the wheel of the serious, we look at the wheel head manufacturers to know how much the headache index. Especially in the summer, the climate is hot, water vapor is abundant, put this destructive power completely revealed. Grinding wheel distortion, abrupt decline in wheel performance, the accumulation of customer complaints at the desk, inexplicable sadness in my heart. Is the quality of people in the winter wheel warm, but in the summer people pull psychological pull cool? Yes, that is what we are discussing about the role of this third party, especially Water 3.
The gap between the resin liquid film and the sand is very narrow, and the third person should not be able to easily enter. But the reality is that it does enter, and have a large area of damage. The secret lies in the sand: the resin film on the surface of the sand to attract this third party. At present, the domestic resin solution generally absorb moisture serious, even in such a small gap, it can also attract water 2 into the water 3. Incidentally, advertising is what I have been fighting for 12 years of the United States Han Mori's phenolic resin plant in Zhenjiang put into production, the problem is expected to be essential to improve.
Possible solutions to water 3 are:
1, must first use non-absorbent resin solution;
2, select the appropriate resin solution, so that the surface of the sand film coating integrity;
3, slow cooling, to avoid cracks in the resin liquid film;
4, other solutions see the water 2 solution.
The attenuation problem is so complex that the factors that affect it are so numerous that they can be improved without end. However, the market is so cold, in the case of lower and lower product prices, how can you cut prices? In addition to improving quality, product segmentation, specialization, you have another way to go?

Wheel material knowledge popularization
Speaking of wheel we should not feel strange, yes it is our life the most common kind of abrasive, and according to the different materials to grind, grinding wheel also has a material. As the largest amount of abrasive, the use of the highest frequency of a grinding tool, today Xiaobian to take you to analyze the wheel material and their respective characteristics, which come with Xiao Bian to see it!
What is the wheel
The grinding wheel is made of abrasives and various kinds of abrasives in China. Generally, there is a round hole in the middle. When the motor is started, it can rotate rapidly. It can be used for all kinds of metal and other Materials for processing. Grinding wheel manufacturing process is more complex, generally compacting, drying and other procedures, some materials have to go through the grinding wheel steps, China is the world's first use of tools to kill one of the countries.
Grinding wheel material and their own characteristics
Ceramic grinding wheel
Ceramic grinding wheel is the name suggests is a combination of ceramic produced out of a grinding wheel it is very stable chemical stability, can be sprinkled in the process of cutting fluid processing, or even dry grinding can be. Some of the plane, both inside and outside the grinding wheel can be used to carry out the processing of ceramic grinding wheel.
Resin grinding wheel
This is a combination of resin made of grinding wheel, so it's hardening temperature is low, shrinkage is also very small, so for some special-shaped or special shape of the wheel, resin wheel is the best, however, to know , Resin wheel in heavy duty conditions continue to work, and can maintain a certain flexibility is not changed, is a very practical wheel.
Rubber grinding wheel
Rubber grinding wheel has a very good flexibility, when we want to polish the surface of building materials such as processing, rubber grinding wheel comes in handy, and it can also do centerless grinding wheel, etc., are often used to cut or slot.
Superhard abrasive wheel
The emergence of this "heavyweights" is closely linked with the diamond, there are a lot of cubic nitrogen nitride stretched wheel can also be classified as superhard abrasive wheel, when we want to carry out some alloy steel and Heat-resistant steel and other material cutting, the superhard abrasive wheel has become our best helper.
Said so much, I believe we have a different material of the grinding wheel has a certain understanding, and finally Xiaobian to remind you that due to the use of grinding wheel in the process often use a variety of additives, so we have to fully understand the various materials Of the grinding wheel on the basis of chemical stability and then the choice of grinding wheel, so as to make our project more with less!
