Blog #depressed grinding disc in stock

The depressed grinding disc in stock and grinding wheels are one type of tools. Diamond tools are tool products that use a bonding agent to consolidate diamond (generally referred to as synthetic diamond) into a certain shape, structure, size, and for processing. Broadly speaking, diamond abrasive pastes, rolling saw blades, cold-set diamond wire drawing dies, cold-set diamond knives, brazed diamond composite knives, etc., are also diamond tools.

In terms of product types, China's diamond tool companies mainly produce: diamond saw blades, diamond drill bits, diamond bowl mills and diamond cutters, diamonds, diamond resin grinding blocks and other products. Among them, the diamond saw blade is a large variety of diamond tool enterprises in China.

1. According to the bonding agent, there are three categories: resin, metal and ceramic bond diamond tools. Compared with the metal bond carcass, the resin and ceramic bond carcass have low strength and are not suitable for sawing, drilling and dressing tools, and generally only abrasive products.

2. According to the metal bond process is divided into: sintering, electroplating and brazing and other categories.

3. According to the structure of use, there are:

a. Abrasives - grinding wheels, rollers, rollers, grinding wheels, grinding discs, bowl grinding, soft grinding discs, etc.;

b. Sawing tools - circular saw blades, row saws, wire saws, band saws, band saws, chain saws, wire saws;

c. Drilling tools - geological metallurgical drill bits, oil (gas) well drill bits, engineering thin-wall drill bits, stone drill bits, glass drill bits, etc.;

d. Other tools - dressing tools, knives, wire drawing dies, etc.

Diamond is hard, so the tool is especially suitable for processing hard and brittle materials, especially non-metallic materials, such as stone, wall tiles, glass, ceramics, concrete, refractory materials, magnetic materials, semiconductors, precious stones, etc.; can also be used for processing colored Metal, alloy, wood, such as copper, aluminum, hard alloy, hardened steel, cast iron, composite wear-resistant wood. At present, diamond tools have been widely used in construction, building materials, petroleum, geology, metallurgy, machinery, electronics, ceramics, wood, automotive and other industries.

Due to various reasons in the manufacture and installation of diamond depressed grinding disc in stock, the center of gravity of the diamond grinding disc often does not fit with its center of rotation. This will cause the grinding disc to vibrate at high speeds, which will affect the processing, and will cause the diamond cutting piece to break when it is severe. And the machine tool is damaged, so the diamond cutting disc must be statically balanced after it is mounted on the flange. After the diamond grinding disc is mounted on the flange, the flange is placed on the mandrel and placed on the gimbal rail.

If it is unbalanced, the heavier part of the cutting piece will always turn to the bottom, move the balance block position inside the ring tip of the flange, balance the center of the cutting piece, and repeat until the disc is on the rail. Can be stationary, at this time the cutting piece reaches a static balance. When installing a new cutting piece, the depressed grinding disc in stock should be statically balanced twice. After a static balance, install the grinder and trim the shape of the cutting piece with a diamond pen, then remove the grinding disc and perform a static balance before installation.

When it comes to the depressed grinding disc in stock, it is a grinding disc made of resin, which has high strength and is applied to cutting piece, double end face, heavy load grinding disc, polishing disc, etc. It has certain elasticity, low heat resistance and good self-sharpness. Simple and short process cycle; widely used in rough grinding, rough grinding, cutting and free grinding, such as grinding steel ingots, casting burrs, etc. What are the performance and application of resin grinding discs in the following grinding disc ultra-thin manufacturers?

1. The resin binder is an organic binder. The binder produced by the binder has high strength, certain elasticity, low heat resistance, good self-sharpness, simple production, short process cycle, and high manufacturing speed. 50m/s grinding disc and very thin depressed grinding disc in stock. Its application range is second only to ceramic bonding agent, widely used for rough grinding, rough grinding, cutting and free grinding, such as grinding steel ingots, casting burrs, etc. High-gloss grinding disc, heavy load, cutting and grinding discs with special requirements.

2. At the same time, the depressed grinding disc in stock is a tool with a large demand. It is made by bonding phthalic acid and polyamide or other resin as a binder by gluing diamond or cubic boron nitride (CBN) abrasive with inorganic filler. A tool that is being used effectively in a variety of grinding operations, such as surface grinding, centerless center grinding, slotting and internal grinding. It is used in super heat resistant stainless steel, metal. An ideal grinding tool for ceramics, ceramics, glassware, limonite, high speed steel, alloy tools and many other new superhard materials.

Nowadays, there are many special depressed grinding disc in stock for fast cold cutting. These discs are especially suitable for the grinding of carbide tools (such as saws, cutters, drilling tools, end mills, etc.). In addition, these tools It can also be used for precision grinding of cemented carbide molds, rollers and carbonized wear parts. Resin-bonded grinding discs are the first choice for the precision machining of ceramics and the thermal spray coating of tungsten carbide and ceramic products. The depressed grinding disc in stock can also be used in conjunction with CBN. For grinding high speed steel, tool and die steel and superalloys above FtRC50.
