They are equally effective in grinding different materials, from hardened steels to aerospace alloys, providing manufacturers with a single solution for multiple grinding needs. This adaptability makes Grinding Wheels For Metal an invaluable asset in diverse manufacturing environments, from high-precision toolmaking to large-scale automotive production.
Types of Grinding Wheels For Metal
Grinding wheels - along with other more portable grinding products like cones and plugs - come in various styles. Selecting the right type of wheel for a given application allows users to get demanding metal fabrication jobs done quickly and accurately. There are three main types of grinding wheels, where various numbers differentiate between wheels with specific properties and uses - type 1 snagging wheels, type 27 grinding wheels and type 28 grinding wheels.
TYPE 1
A type 1 snagging wheel has a straight profile and a relatively small diameter of about 2 to 4 inches. Its size makes it ideal for use on high-speed die grinders for grinding off excess metal. Type 1 snagging wheels incorporate aluminum oxide grains for a long life grinding and a consistent cut-rate.
TYPE 27
Type 27 is by far the most common abrasive grinding wheel. Type 27 grinding wheels differ from other wheels in that they have a flat profile with a depressed center. A depressed center allows for clearance when the operator must work at a constrained angle. Using a wheel with a depressed center allows for a range of grinding angles, typically from 0 to 45 degrees. However, the optimal angles for working with type 27 grinding wheels range from 25 to 30 degrees. The steeper the grinding angle, the more aggressive the cut will be. Working at shallow angles with these wheels requires some consideration of potential ramifications. Grinding at shallow angles can prolong the wheel's lifespan, but it also often compromises the cut-rate. On harder materials, shallow grinding angles may also increase unwanted vibration and chatter.
TYPE 28
Type 28 grinding wheels, also known as saucer wheels, have similarly depressed centers and are optimized for low grinding angles. They differ from type 27 wheels in that their concave or saucer-shaped design allows for better access to the workpiece - especially in tighter areas, such as corners, fillets and overhangs - and increased aggression at smaller working angles. They can work at angles between 0 and 30 degrees but typically work best for use with grinding angles from 0 to 15 degrees.
Factors to Consider When Choosing Grinding Wheels For Metal
When it comes to choosing the best metal grinding wheel for your project, there are several factors to consider such as type, grit size, bond strength, wheel hardness, and application type.
Grinding wheel bonding materials play an essential role in determining the grinding wheel's properties, including strength, durability, and cutting efficiency. There are various bonding materials used in grinding wheels.
★Vitrified Bonds: Vitrified bonds are one of the most commonly used bonding materials in grinding wheels. They are made of a mixture of clays and feldspars that are heated to high temperatures to create a glass-like bond. The vitrified bond provides excellent strength and rigidity, which makes it ideal for precision grinding applications.
★Resin or Resinoid Bonds: Resin is another popular bonding material used in grinding wheels. Resin bonds are made from synthetic resins mixed with abrasive grains and fillers. They offer excellent cutting properties, which makes them ideal for grinding applications requiring high stock removal rates. Resin bonds are also flexible and can absorb shock, so they are ideal for grinding applications involving high vibration.
★Silicate Bonds: This type of bonding material is used in grinding wheels and it contains a mixture of silicate and clay. Silicate bonds are used in applications that require low cutting forces and high precision, which makes them ideal for grinding applications that require a smooth surface finish.
★Shellac Bonds: Shellac bonds are made of natural resins and they are primarily used in small grinding wheels. Shellac bonds are typically used in applications that require high precision and low cutting forces, such as sharpening tools.
★Rubber Bonds: This type of bond is used in applications that require high elasticity and vibration damping. Rubber bonds are ideal for grinding applications that involve delicate workpieces or materials that are prone to cracking or breaking under stress.
★Type 27: These wheels have a flat profile and indent in the center, so they are an optimal choice for stock removal between 25-35 degrees. Furthermore, they are exceptionally effective even when used at angles up to 45 degrees.
★Type 28: Type 28 wheels feature a concave design that allows them to perform best at angles between 0 and 15° from the surface. This type is ideal for those who need to access narrow spots or require more aggressive working angles.
★Ceramic Alumina: Ceramic alumina grinding wheels are especially useful for applications where high accuracy and surface quality are required. Ceramic alumina grinding wheels offer superior performance compared to conventional aluminum oxide abrasives due to their higher strength and hardness as well as their greater resistance to wear and tear.
★Zirconia Alumina: With zirconia alumina grains, you get a powerful combination of both speed and durability. This self-sharpening grinding material performs superbly on metal surfaces such as steel and stainless steel, even under heavy pressure or extreme temperatures.
★Zirconia Alumina Blended with Ceramic Alumina: Zirconia alumina blended with ceramic alumina is an ideal material for grinding wheels due to its high hardness, strength, and wear-resistance. This combination of materials provides a durable wheel that can be used for a variety of applications. Its high melting point makes it a perfect choice for use in grinding wheels that will experience extreme heat during operation. The addition of ceramic alumina increases the hardness and wear resistance of the wheel, in order to allow it to withstand more aggressive grinding operations.
★White Aluminum Oxide: It is an angular, durable, and hard material that can be recycled multiple times without losing its cutting edge. It is also known for its high heat resistance, which makes it suitable for use in high-speed grinding applications. White aluminum oxide has a wide range of uses including grinding, polishing, lapping, abrasive blasting, and anti-slip aggregate. It is often used to grind metals such as steel and stainless steel as well as other materials like glass, stone, and plastic.
★Aluminum Oxide: Aluminum oxide grains are the perfect tool for grinding steel, iron, and other metals. Its hardness makes it a fast initial cut option, yet its efficiency diminishes over time in comparison to wheels made with other types of grain - which often have higher longevity.
★Silicon Carbide: Abrasive and fast-acting, silicon carbide is an ultra-hard grain that offers quick cutting but lacks the toughness of other grains.
★Silicon Carbide/Aluminum Oxide Blend: For the best grinding experience on aluminum and other soft metals, a wheel composed of both silicon carbide and aluminum oxide is the ideal choice. The combination of these two substances results in quality cut rates that are faster than average, while also providing an extended lifespan for alloys such as aluminum.
Materials of Grinding Wheels For Metal
The materials in each grinding wheel break down into a few main components - the grains, the bond and the fiberglass that reinforces the wheels to give them strength and stability for use in demanding applications. The grit of the wheel is also an essential element that helps determine performance.
Grains and Grain Blends
The abrasive grains provide the essential functionality of a grinding wheel because they remove material from the workpiece. A few commonly used grinding wheel abrasives are ceramic alumina, zirconia alumina, aluminum oxide, white aluminum oxide, aluminum oxide and silicon carbide. Grains can be blended together to achieve different performance characteristics as well.
★Ceramic alumina: These grains offer the benefit of self-sharpening and micro-fracturing crystals. They are relatively cool when in use, and they provide the longest operating life under moderate to high pressure. They grind at lower temperatures and generate less friction - one main benefit of these qualities is that they minimize heat discoloration on the workpiece. Ceramic alumina is ideal for hard-to-grind metals such as armored steel, titanium, hard nickel alloys, tool steel and stainless steel.
★Zirconia alumina: Zirconia alumina grains provide a fast cut and a long life on metal workpieces. They are self-sharpening and deliver rapid, consistent grinding, especially on metals like steel and stainless steel. They also hold up well under high pressures and extreme temperatures.
★Zirconia alumina blended with ceramic alumina: If you like the performance of a zirconia alumina grinding wheel but are looking for an extra boost a blend with ceramic alumina will deliver faster cutting with less effort.
★White aluminum oxide: White aluminum oxide grinding wheels offer a relatively fast cut-rate and an extensive lifespan. They are ideal for grinding stainless steel and harder-grade steel.
★Aluminum oxide: An aluminum oxide grain is ideal for steel, iron and other metals. Although it is hard and durable and provides a sharp, fast initial cut, the grain dulls over time and lacks the cut-rate and potential longevity of some other grains. Aluminum oxide provides exceptional value and cost-effectiveness while still offering the excellent quality and consistent performance necessary in a grinding wheel.
★Silicon carbide: Silicon carbide is an extremely hard grain that is very sharp and fast cutting but friable, not as tough as other grains.
★Silicon carbide/aluminum oxide blend: A wheel made from a blend of silicon carbide and aluminum oxide provides ideal grinding for aluminum and other soft alloys. These grains offer extended life spans and fast, consistent cut rates on aluminum and other soft metals.
Bonds
The bond is the substance that causes the abrasive grains to adhere to the wheel. Bonds can consist of different materials. Common materials include shellac, resinoids, rubber and glass or glass-ceramic. The bond on a grinding wheel may be either hard or soft. A harder bond extends the wheel's lifespan, provided the user operates and maintains the wheel correctly. A softer bond, on the other hand, allows for smoother grinding and exposes new grains more quickly. Choosing the correct bond for a given application can help balance performance and longevity. The type of metal can also influence the bond that's best for your application.
Grit
The grit of a wheel is critical for supplying the right abrasion. Grit measurements generally range from coarse to fine. The coarsest grit has a rating of about 24 and the finest grit - the grit on snagging wheels - has a rating of about 36. Selecting the right grit level for a particular application helps ensure sufficient grinding power. A course grit has a better removal rate, while a finer grit requires less pressure during application and allows for a better final finish on the workpiece.
