Today we will take a look at the grinding discs used in portable grinders and then share with you my experience in using them. Hello friends, today we will take a look at the grinding discs used in these portable grinders. These are the ones I just have on hand. By the way, I would like to introduce to you and share my experience in using this portable grinder. In fact, it has many uses. The three main uses are cutting, grinding and polishing. In order to achieve these three purposes, we must install different grinding wheels. These on hand are mainly divided into two types: grinding and cutting. The right hand side here is the grinding type. This row is the cutting type. Let's first look at the cutting part. The cutting type is more commonly used , and we can divide it into cutting metal and cutting. Stones include concrete , general cement, stones, marbles, and other metals and stones. Different grinding discs are used for metals and stones. The cutting discs I have on hand can be divided into three categories : those for cutting metal and those for cutting stone. This type is a comprehensive type. Generally speaking, the pieces used for cutting metal will be thinner. It will be marked on it as being used for cutting metal. It cannot be mixed with cutting stone. We need to use this kind of specialized cutting piece. Basically, the design of stone is different from that of metal. The material is also different. I have two pieces here , mainly because the thickness is different. This one is thicker and this one is thinner . Generally, there is this one here. This kind of design is mainly used for you to discharge the chips of your stone or concrete. I bought it to cut the gap between the tiles because some tiles and tiles are relatively thin. The gap is relatively small , so if you use this thicker one, you may cut into the tiles. The main design of this universal type is that it can cut anything. The edge is diamond . Basically, it can cut metal, concrete, wood, PVC. It is mainly used for cutting. If it is used to cut composite materials, it is much safer than metal slicing because metal slicing has the risk of cracking, while composite materials like this only have edges. There is a ring of this diamond that is made of iron , so there is no risk of it breaking. But this kind of diamond is thicker than ordinary metal slices, so the efficiency of cutting metal with this diamond will be higher than that of cutting metal specifically. It's a bit lower. There is also a grinding wheel on the market that is specially designed to cut wood. That type of grinding wheel is very dangerous. It is recommended that you never install a grinding wheel for sawing wood . So if you are not an experienced hand and feel that the grinder is more dangerous, you can consider using this one. It is a general-purpose saw blade that can cut everything and there is no risk of breakage. After talking about the cutting part, let’s take a look at grinding concrete or stone. It is relatively simple . Its grinding blade will look like this. This also has With diamonds inside, it can grind concrete, cement, and metal. There will be many grinding options . Then we can divide it into two types: coarse grinding and fine grinding. We can divide the rough mold part into two situations . One is When we grind, we want to grind off the metal. So we need to use a coarse grinding like this, and then we can grind the metal off. There is a kind of coarse grinding. We don't want to damage the metal itself , we just want to remove the oxides on the surface. To remove rust or paint , we can choose something like this. Let's compare this kind of rough grinding. It will grind away the metal itself and grind it into the shape you want . Generally, its thickness will be thicker . This is very hard, very hard, so it can grind the metal away. Everyone, please pay a little attention to the slice of the metal we just mentioned. This slice is designed to be thin . It can only be used for cutting and not grinding. Never place your workpiece on this side and let it grind like this , because it can easily cause the slice to burst, which is very dangerous. If you want to grind roughly without grinding off the metal itself, you should choose People usually call it black wheel, or purple wheel, and some people call it purple diamond. Both of these are very suitable for rust removal and paint removal. The biggest difference is that black wheel is softer. This purple diamond is harder and softer, so relatively speaking it will not harm the metal itself. Sometimes there is some rust, which is very stubborn , or when the paint is more stubborn, the softer one will be less efficient . There are two types, one is soft and the other is hard . You can choose the type of emery cloth wheel you need according to the situation. It can also be used for rust removal or paint removal. Generally speaking, there are harder and softer emery cloth wheels like this one. It will have a difference in number. The bigger the number, the finer it will be. After rough grinding, we will use a fine grinding like this. After fine grinding, we will use this polishing. The fine grinding part . I I prefer to use a vegetable cloth material like this. For example, if you use this black wheel to remove rusty parts on the surface or remove paint , you want to make the surface look more shiny or have some rough ones. If there are scratches, we need to use this kind of fine grinding. This kind of material is relatively hard, so I personally think it is difficult to use . It is like this brand of vegetable cloth wheel . I think the effect is quite good. There will be a display on the metal used. There is also a difference in the number. It seems that this is No. 120, No. 220 and No. 400. Generally, when we grind, the one with the smaller number is grinded first because the one with the smaller number is compared. If it is rough , I will use a larger number in the end and then grind away the thicker marks to make it smoother. You can take a look at the reverse side of this one. I personally use a lot of them and it is easier to use. If you need to after fine grinding, For polishing , we will need this kind of cloth wheel. Generally, we use this kind of cotton cloth wheel. This kind is made of cloth . This kind is made of wool. This kind is also a wool wheel. It is white because I have some abrasive paste on it, so It doesn't look white , but it's actually a white wool wheel , but it's flat. It's three-dimensional. It looks like this. It stands up piece by piece. I personally think that the three-dimensional type is better than the flat type. This type of wool wheel is mostly used when a relatively large area is flat. If you have a flat wool wheel with curves, it is not easy to use, so you need to use a three-dimensional wool wheel. Personally, I use this one a lot and I think its effect is quite good. You can refer to it and add some polish paste or abrasive paste . Stainless steel and the like can be polished very well. bright For example, a cooking table will have a lot of stainless steel parts. Today, the grinding disc of the portable grinder will be simply shared with you here. If you like my video, please give me a like and share my video . Goodbye next time
