In 2016, the market size of metal cutting machines was estimated at US$5.99 billion. Demand for multiple industries such as automotive, defense and aerospace, electrical and electronics, and construction continues to grow.
Abrasives are still a misunderstanding method of cutting. Many people have come to the conclusion that due to its name, it leads to a rough surface.
So if you want to know what the abrasive means? You are not alone. Abrasives define irregularly shaped particles that are used to cut by cutting material from the surface of the workpiece.
When choosing the right large diameter metal grinding disc, you need to know the basics first.
Read on to learn about the advantages and components of large diameter metal grinding discs.
1. Produce a smooth and flat surface
The metal grinding disc ensures precise metal cutting. They are applications that can handle tight tolerances and high precision.
If you are looking for a way to achieve high volume cutting at a moderate price, consider using a large diameter metal grinding disc.
The main advantage of the large diameter metal grinding disc to remove metal from the surface of the workpiece.
They have the ability to grind and corrode workpieces to help you achieve a smooth and accurate surface.
2. Cereal dress
These non-reinforced abrasive cutting wheels have a myriad of sub-micron cut particles. They dress themselves when they are tired.
Usually, matt grain will fall off, resulting in sharp edges.
Each time they are used continuously, they will continuously show a fresh cutting edge. It ensures that you don’t have to worry about maintenance.
3. Wide range of uses
In addition to rods and extracts, metal grinding discs can also be used to cut tubes and dielectric materials.
You can easily cut unrestricted composite metals and coated metals.
4. The metal grinding disc works fast
The metal grinding disc works faster. Compared with other precision cutting methods.
You can even bundle the materials you need to cut to save on the cost of high-volume cutting. This is a very effective advantage, because for more material bundles, you will also get a smaller diameter.
5. Cutting extremely hard materials
The bench-top metal grinding disc achieves a neat surface finish even with extremely hard materials. They produce the best surface finish compared to other cutting options.
In addition, the cooled thin metal grinding disc abrasive ensures that little heat is generated. Very useful when machining on workpieces.
6. There are many options
The development of synthetic abrasives is growing. This adds to the existing natural cutting abrasives.
Do you want to know what the abrasive means? They are sharp, hard materials that are used to wear the workpiece.
Even if their movements are irregular, they can produce a smooth, accurate surface. In addition, blunt abrasive particles typically fall off the bond material, causing the cutting edge to become sharp.
Artificial abrasives include;
Aluminum is commonly used to make abrasives of different purities. This helps achieve different grid levels. For example, a white alumina metal grinding disc grinds high-strength heat-sensitive steel.
Silicon carbide is harder and more brittle than alumina. Black silicon carbide can be used to cut cast iron, non-ferrous metals and non-metals. On the other hand, raw silicon carbide is used for cutting or grinding cemented carbides due to brittleness.
Cubic boron nitride
This is a very hard abrasive that allows you to achieve sharp and cool cuts.
It is one of the latest manufactured abrasives. They are used in stainless steel, the hardest cast iron and super hard high speed steel.
You can use a metal coating with excellent bond adhesion for general purpose grinding. Alternatively, there are uncoated abrasives for vitrified bonding systems and electroplated metals.
Although natural diamonds have been around for decades, synthetic diamonds have become increasingly popular. This is due to its reasonable price.
Synthetic diamond is used to grind hard and very hard steel. On the other hand, natural diamonds can be used to cut stone, carbide and granite.
The bonding material typically holds the abrasive on the metal grinding disc. The following are the standard adhesives used on concrete grinding disc for angle grinder.
I. Vitrified bond
This is the most common abrasive used with large diameter metal grinding discs.
Ceramic binders are usually made by mixing ground clay and flux. A preferred abrasive is typically added to the mixture and bonded to the cutting wheel.
Ii. Resin key
This is the second most popular bond, usually a phenolic resin in powder or liquid form.
Resin adhesives are used for rough grinding and cutting operations.
Iii. Silicate bond
Silicate adhesives are often the ideal choice to keep the heat generated during grinding and cutting to a minimum. However, silicate adhesives tend to release abrasives compared to other adhesives.
Iv. Shellac bond
Shellac is an organic bond that gives you a smooth surface finish. However, it does not apply to heavy work.
v. Rubber key
These are extremely sturdy joints designed for centerless grinding machines. They enable you to achieve extremely thin surface finishes on your workpiece.
Vi. Metal key
Last but not least, we have a metal bond that works with diamond abrasives. They can be used for electrolytic grinding because the metal is electrically conductive.
Abrasive grain size (particle size and particle size)
Abrasive size is important because it usually affects cutting speed. Moreover, it affects the surface finish obtained and the chip gap.
The size of the abrasive can be determined by the nature of the particle size and coarse sand.
Each metal grinding disc has a number that indicates the characteristics of the grit. It is based on the size of individual abrasive particles in the metal grinding disc. A low grain size number means a large particle size and vice versa.
The following are the abrasive content and the ratio of particles to grit;
Very good 220-1,000
Wheel structure and grade
When it comes to metal grinding disc shape, you can use cylindrical, cup or bowl metal grinding discs. There are also intermittent and continuous metal grinding discs.
A fixed metal grinding disc is a wheel that is permanently attached to a mandrel.
The structure of the metal grinding disc is usually determined by the pacing speed of the abrasive particles on the surface of the metal grinding disc.
Finally, the grade indicates the strength of the bonding material used.
Large diameter metal grinding discs ensure a smooth, accurate surface finish. Using the right abrasive consumables ensures that you get the right product for your store.
