What Exactly Is a Resin Grinding Wheel?

A resin grinding wheel is a high-strength resin grinding wheel. It is found in cutting discs, double-end faces, heavy-duty grinding wheels, polishing wheels, and other applications. It has elasticity, low heat resistance, good self-sharpening, simple production, and a short process cycle; it is widely used in rough grinding, rough grinding, cutting, and free grinding, such as grinding steel ingots, casting burrs, and so on.


Introduction

A resin grinding wheel is a grinding wheel made of resin, such as phenolic, epoxy, polyurethane, polyvinyl alcohol, and so on; a resin grinding wheel has high strength and can add reinforcing fiber mesh and steel bars to the grinding wheel, such as cutting discs, grinding discs, and so on; most of our resin grinding wheels are made of resin. Because resin grinding wheels are not waterproof, they cannot be ground with grinding fluid. Naturally, some resin grinding wheels require the use of a grinding fluid, such as epoxy resin. The resin grinding wheel has good grinding smoothness, and the workpiece does not burn easily. The resin bond grinding wheel is used in cutting discs, double faces, heavy-duty grinding wheels, polishing wheels, and other applications; its strength is lower than that of metal bonds and vitrified bonds.


Applications And Features

An organic bond is a resin bond. This bond produces a grinding wheel with high strength, elasticity, low heat resistance, good self-sharpening, simple production, and a short process cycle. Grinding wheels with speeds greater than 50 m/s and very thin wheels can be produced. Its application range is second only to that of vitrified bond, and it is widely used in rough grinding, rough grinding, cutting, and free grinding, for example, grinding steel ingots, casting burrs, and so on. It can produce high-speed, high-finish grinding wheels, as well as heavy-duty, cutting, and other special-required grinding wheels.


At the same time, the resin-bonded grinding wheel is a highly sought-after tool. It is a tool made by bonding diamond or cubic boron nitride (CBN) abrasives with inorganic fillers with binders such as benzoic acid, polyamide, or other resins. This tool is useful for a variety of grinding operations, including surface grinding, external centerless grinding, grooving, and internal grinding. It is an excellent grinding tool for superhard materials such as stainless steel, cermet, ceramics, glass, limonite, high-speed steel, alloy tools, and many others. There are numerous special resin-bonded diamond grinding wheels available for rapid cold cutting. These grinding wheels are ideal for grinding carbide tools such as saws, cutters, drills, end mills, and so on.


Furthermore, these tools can be used to precision grind carbide dies, rollers, and carbide wear parts. Resin-bonded grinding wheels are the preferred method for precision machining ceramic products, as well as for grinding tungsten carbide and thermal spray coatings on ceramic products. Resin-bonded grinding wheels can also be used in conjunction with CBN to grind high-speed steel, tool and die steel, and superalloys with FtRC50 or higher.


Cleaning Method And Installation

The cleaning method:

The emery wheel is utilized during the manufacturing process to grind the belt. After 5-7 days of use, the grinding wheel should typically be removed and cleaned. Now we soak it in acetone for 2 hours and clean it with the imported cleaning agent, the effect is very good but it is not environmentally friendly and does not save energy (there are polished rubber scraps on it, which are tightly attached to the emery surface after high-temperature friction, so it is difficult to clean).


Cleaning specifications

1. To be non-halogenated hydrocarbons, free of ketones, and environmentally friendly.


2. Is unable to harm the diamond wheel.


Installation guidelines:

Before installation, grinding wheels need to be thoroughly inspected and identified. To check and identify, follow these steps:


1. Verify the grinding wheel's grade and that its performance, shape, and size correspond to those of all the chosen grinding wheels.


2. Examine and note the grinding wheel's structure and appearance. Check the wheel visually for damage (or cracks). Visually damaged (or cracked) grinding wheels cannot be used. The grinding wheel must also have flat ends on both sides and cannot have any obvious skews.


3. Check the grinding wheel for internal cracks and mark them. Hold the grinding wheel in your hand and tap it with a wooden hammer to hear the sound. A grinding wheel without cracks produces a clear sound, whereas one with cracks produces an unusable hoarse sound.


Classification

According to the abrasive, resin grinding wheels are typically divided into ordinary resin grinding wheels and superhard resin grinding wheels. A super hard resin grinding wheel is a grinding wheel with diamond or CBN as the main grinding component, while an ordinary resin grinding wheel is a grinding wheel with white corundum, brown corundum, silicon carbide, and other common abrasives as the main grinding component.


Ordinary resin cutting discs and ordinary resin grinding discs are the most widely used resin grinding wheels on the market. Diameters 100, 180, 230, 300, 350, 400, and 500 are typical.


Super-hard resin cutting discs and super-hard resin grinding discs are the two main products available on the market for super-hard resin grinding wheels. Common cutting discs have diameters of 100, 125, 150, and 200. Common grinding discs have diameters of 150, 200, 250, 300, and 400.
