Introduction of commonly used cutting blades

?The organization of the dicing sheet is the distribution of the proportion of the abrasive, the binder and the stomata in quantity. Simply put, the distance between the abrasive particles. The distance between the abrasive is very difficult to measure, in volume percentage of6 inch es cutting disc occupied, i.e., an abrasive as the criterion tissue.
Depending on the tissue, it is possible to make tight or loose cutting pieces of different densities to suit different grinding conditions. After the abrasive particles of the cutting piece are blunt, they can be quickly broken to expose the new blade to continue grinding.
The densely-cut piece has less pores, and the loose tissue has more stomata. While the weak binding of many pores, but large cutting space, cutting performance can be improved. A large cut piece is known as a large cut hole and a small number of holes; a small cut piece with a small number of holes and a large number of holes is called a dense cut piece.
Simply put, the cutting piece of the atmospheric hole is suitable for grinding soft and sticky materials, such as aluminum, copper, etc.; otherwise, it is suitable for grinding hard and brittle materials.
Shape of the cutting piece
The shape of the cutting piece is roughly divided into five types, a flat shape, a beveled edge (double beveled edge, a single beveled edge), a dish shape, a bowl shape, and a cup shape.
Flat cutting discs are the most widely used, grinding planes, outer circles, slots, etc., and can be shaped into various shapes for shape grinding according to actual needs.
It is not necessary to talk too much about the beveled cutting piece. Everyone understands that the woodworking ordinary saw blade uses a single beveled cutting piece.
Dish and bowl cutting blades are commonly used to grind various tools and cutting tools, such as drills, milling cutters, and the like.
The cup-shaped cutting piece can be used for various purposes, such as the cutting piece used in the machine for grinding the planing knife, and the bowl-shaped cutting piece can also be used for vertical grinding of the plane, which is highly efficient, and has the disadvantage of poor heat dissipation.
Commonly used are stalked cutting pieces (such as those used in electric grinders), etc. The cutting pieces can be made into a variety of shapes to suit different needs.
Storage and transportation of cutting sheets
The strength of the cutting piece is low and it is easily affected by factors such as temperature, humidity, vibration, collision, extrusion and storage time. It is of great significance to prevent the accident by properly storing and transporting the cutting piece. To do this, the following should be done:
1. The cutting piece should be stored on a dedicated storage rack.
2. The storage of the cutting piece should be reduced as much as possible to prevent cracks from impact and vibration. The cut sheet is brittle and should not be hit, dropped or collided.
3, storage of rubber bond cutting tablets should be careful not to touch the oil; resin bond cutting tablets do not touch the alkali solution. Ceramic abrasives should not be placed in wet or frozen areas, otherwise the strength and grinding force of the tools will be reduced.
When the resin and rubber bond cutting sheets are stored, they should be sandwiched between two smooth and flat metal plates. The metal plate should be larger than the diameter of the cutting piece. Do not put it under the damp and fan directly to prevent bending deformation. The cutting piece can not be stored for a long time. If the resin and rubber deteriorate for more than one year, it must be strictly inspected before use.
The rubber and resin bond sheet cutting sheets should be prevented from being deformed during storage.
4, the cutting piece should be stored in accordance with the manufacturer's instructions, expired cutting pieces can not be used casually.
5. During the transportation of the high quality cutting disc supplier, it cannot be installed with metal objects; and reduce vibration and impact.
5?? The abrasives should be stored in a dry place, the room temperature is not less than 5 degrees Celsius; when the cutting pieces are stacked, the stacking height is generally not more than 1. 5 m.
7. Abrasive tools should be placed separately according to specifications. Marks should be placed in the storage to avoid confusion and errors. The placement method should be determined according to the size of the grinding. Grinding tools with large or thick diameters should be placed upright and slightly inclined. Thinner and smaller cutting pieces should be placed flat, but should not be too high, and a flat iron plate should be placed underneath it to prevent cutting. The piece is deformed or broken.
