150mm sanding disc is also called steel paper grinding disc, high-speed grinding disc and grinding disc, among which sand disc and steel grinding disc are used more. It is a disc-shaped coated abrasive formed by using steel paper as the substrate, silicon carbide or corundum as the abrasive, and bonded by synthetic resin or other synthetic binders.
Features of 150mm sanding disc
150mm sanding disc is a characteristic product among coated abrasives. Its substrate is rigid and tough. Therefore, its use and manufacture have some outstanding features compared with other varieties. These features are as follows:
(1) The production is simple and the cycle is short
The production mechanization degree of the sand table is very low, and it is simple mechanical or manual production, so not only the facilities are simple, but also the operation is easy to master. For a batch of products, the production cycle is shorter, but the production output is not much, that is, the production efficiency is low.
(2) High strength and good toughness
The matrix of the sand disc has high strength and good toughness. In addition, the binder it uses is a high-strength binder, so it is suitable for grinding workpieces at high speeds and high loads, and its linear speed can reach 100-130m/s.
(3) Good rigidity, completely reliable in use
150mm sanding disc has good rigidity and flexibility. Although the steel paper is used as the substrate, the bending property is poor, but it has high strength and high toughness, and it is not easy to break under the action of high-speed rotation and high load. The processing process does not produce the dangers that may occur during grinding wheel processing, and it is a relatively safe and reliable tool to use.
(4) Easy to use and flexible, good processing effect
The 150mm sanding disc is small in size and light in weight, and is installed in a portable fan. This kind of machine is compact and flexible, and it is extremely convenient to operate. It can grind large surfaces, and it is also more suitable for grinding irregular surfaces, and its processing effect is very good.
(5) There are many specifications and varieties, and the application is wide
150mm sanding disc can be divided into disc shape, polygon shape and ruffle shape according to the shape. The abrasive material can be divided into different types of abrasives, among which various abrasives have different particle sizes, and disc-shaped sand discs can be divided into multi-standard products according to the size of the hole diameter and the diameter of the outer circle.
The 150mm sanding disc with holes facilitates the discharge of waste chips from the holes when sanding objects, improving sanding efficiency. The 150mm sanding disc without holes depends on the requirements of the workpiece to be ground. The abrasive selection of the product also depends on the workpiece to be ground, such as black silicon carbide disc sandpaper. Brown corundum disc sandpaper, ordinary brown corundum disc sand, calcined brown corundum sand, zirconium corundum disc sand, etc.。
150mm sanding disc has a wide range of applications. Disc sandpaper is used in the production process of everything from the space shuttle to our mobile phones and computers. Some parts of the space shuttle are sanded with disc sandpaper, and the fuselage is sanded with disc sandpaper before painting, otherwise there will be no stripping of the paint. Take our most commonly used laptop as an example, it can have such a dark exterior color, and rarely has a fine finish that does not fall off the plate. It can also be used for polishing hardware accessories, plastics, electronics, auto parts, furniture and handicrafts. At the same time, the 150mm sanding disc grinds products with high efficiency. Compared with traditional manual sandpaper grinding, it is faster, more convenient and less wasted
Types of sanding discs
Sand discs can be divided into: steel paper discs, sticky discs, etc.
(1) Steel paper grinding disc is the main product in the sand disc. It is a disc-shaped machine-coated abrasive tool made of steel paper as the substrate, silicon carbide or corundum as the abrasive, and synthetic resin as the binder.
(2) Paste-type sanding discs are coated with a layer of self-adhesive on the back of the disc-shaped emery cloth or sandpaper, and protected with plastic-coated paper. The pasted sand table does not need to be fixed with fixtures, so it is very convenient to use. When in use, as long as the plastic-coated protective paper is peeled off, it can be directly pasted on the grinder chassis. After use, it is easy to peel off from the chassis.
Production form of 150mm sanding disc
There are two forms of 150mm sanding disc production: one is to first use a roll of steel paper to coat glue and plant sand on the coated abrasive tool manufacturing machine to make a large roll, and then punch it into a disc-shaped product. The other is to first punch steel paper into disc-shaped paper sheets of a certain specification, and then apply glue and plant sand one by one to make abrasive sheets. The first method has a large production volume, good product quality, and high production efficiency, but it also has relatively high quality requirements for equipment, especially for punching tools. If the general high-carbon tool steel punching tool wears out very quickly and cannot meet the production requirements, steel-based punching tools coated with boron carbide or cubic boron nitride should be used. In foreign countries, laser cutting is being carried out, and laboratory tests have been carried out, but there are no reports of practical production. It is expected that laser cutting is a promising trend. The second method has a small production volume and poor quality stability, but it is easy to operate, simple in equipment, and can be produced by hand.
