Polishing disk structure

The grinding disc comprises a top disc, a buffer plate and a grinding disc; Wherein the top plate comprises a plurality of riveting elements, an upper plate and a lower plate.

Positioning plate, top plate, bolt, lower positioning plate and nut; By improving the bolt structure, the utility model firstly engages the locking part of the bolt itself with the central hole of the top plate to ensure the horizontal accuracy, and then

The polygonal fixing part below the bolt is matched with the polygonal fixing hole opposite to the lower positioning plate to ensure vertical accuracy, thus providing a grinding disc with good fixability and good rotational stability; In addition, the upper threaded section of the bolt is matched,

The design of different outer diameters of the clamping part and the fixing part makes the bolt not easy to loosen, and has the advantages that the internal parts are not easy to wear, and the user's hands will not be sore and numb due to the unstable rotation of the grinding disc.

Polishing is based on a more detailed process after polishing, so the selection of polishing materials is also more detailed. The plane polisher is a kind of equipment specially used to deal with the surface brightness of workpieces, and it has an important configuration-polishing disc.

. The selection of polishing disc is very important, which affects the specific effect of workpiece surface polishing to a certain extent and is an indispensable part of polishing program.

How to judge the advantages and disadvantages of polishing discs?

1. polishing material.

Different workpieces need to use different grinding discs or polishing discs. What material is used for the disc depends on the specific material of the workpiece. For example, sapphire products can be used with copper disks, metal diamonds or stainless steel disks.

2. The granularity of polishing disc should be more delicate.

Polishing is a delicate process, which requires the use of fine discs, not too rough. Only a delicate disk surface can make the surface of the workpiece brighten layer by layer and become as uniform as a mirror. Rough optical discs are not only uneven in effect, but also prone to problems such as scratches on the surface.

3. The polishing disc must have a certain hardness.

Because the workpiece and the polishing disc will produce great friction and heat in the process of high-speed operation, if the polishing disc does not have a certain hardness,

Degree, then it is easy to produce cracks, scratches, edge collapse and other phenomena. If these problems occur on the disc, the polishing quality of the workpiece cannot be guaranteed. Therefore, it is very important whether the hardness of the disk is appropriate. It's too difficult,

Because it is too hard, it is easy to damage the workpiece when rubbing. Therefore, when selecting materials, we try to choose a disk slightly harder than the workpiece material for polishing, and the effect is the best.

4. The material used for polishing the optical disc should have certain heat resistance.

Why should it have heat resistance? There is no doubt that friction generates heat, which is a well-known physical principle. If the grinding disc is not heat-resistant, the temperature of the grinding disc will automatically break or destroy the workpiece after grinding for a certain period of time. Although we will have a cooling device on the plane polishing machine, materials with good heat resistance are more suitable for polishing discs.

Influence of grinding disc on plane machining

When the grinding disc is used on the surface grinder, the flatness of the workpiece surface will be raised after grinding. In order to eliminate the error of workpiece flatness, it is necessary to use a certain convex grinding disc to better ensure the flatness effect of workpiece surface.

In general, in order to keep the convex size of the grinding disc used in the surface grinder, it is necessary to obtain good flatness according to the type, size and specification of the workpiece and the proficiency of the operator, and it is necessary to determine the flatness measurement method of the workpiece and the diameter of the grinding disc.

In mass production and processing, it is generally necessary to trim the grinding disc into the convex amount required by the workpiece. This work is one of them.

It is a complicated work. In single piece and small batch production, the required convexity can be achieved by local heating of grinding disc. In the process of manual grinding, we mainly focus on skilled technology and workpiece leveling.

Will have a certain impact, only in the processing to understand these, in order to get the ideal plane effect on the workpiece surface.

Therefore, what kind of grinding disc or polishing disc customers choose is an important part of grinding and polishing machine processing. Inappropriate grinding disc and polishing disc cannot obtain the final machining accuracy of the workpiece.

Buy directly, know the material of the grinding disc, the diameter of the grinding disc or polishing disc, and their thickness.

If you don't know this, you need to know the material of the workpiece polished by the polishing machine, the model of the polishing machine, whether there is a dressing wheel, etc. These factors can also determine the material and size of polishing disc or polishing disc required by customers.

The grinding discs required for Shenzhen Hyde plane grinding and polishing machine and double-sided grinding and polishing machine are as follows.

The difference is that the plane polishing machine is also called the single-sided polishing machine. When the workpiece is processed, it is mainly to process one side of the workpiece, while the double-sided grinding and polishing machine can process both sides of the workpiece at the same time.

Processing, its processing accuracy is extremely high. The configured grinding discs will be selected according to the material of the workpiece and the required precision effect, mainly including pure tin discs, copper discs, cast iron discs and synthetic tin discs.

For some special materials, such as hardness, precision, etc., imported copper disk or imported tin disk will be chosen as the influencing factors of mirror effect.
