Vitrified Mounted Points of Silicon Carbide Aluminum Oxide

Vitrified mounted points are primarily used for the inner grinding of different metals and dressing mold. They are great for honing, cutting, roughing, deburring, surface cleaning, finishing, etc. Besides, vitrified mounted points are usually preferred by several industries that need precision metal components.

They are conventional mounted points sintered by a ceramic bond, featuring a metal handle in the center. Vitrified mounted points are found in different dimensions and shapes. They are also mostly made up of aluminum oxide and silicon carbide.  For aluminum oxide, they can be white, pink, or brown, whereas for silicon, they can be black and green it should be noted that the bonds used can either be resin or vitrified type.

Important Features

• Feature wear resistance, which offers a long service life and durable grinding mechanics
• High-efficient tools for metal grinding, dressing, and repairing.
• Feature durable and highly-attached metal handles
• Ideal balance control
• Great for high-volume foundry operations and small job shop applications, ensuring less burn, cool cut, and higher metal removal rates

Specifications of Vitrified Mounted Points Products

The market is filled with vitrified mounted points products that have different specifications. During production, the regular material used includes Ruby grains, pink fused alumina (PA), Brown fused alumina/Brown aluminum oxide (Brown corundum [A]), White fused alumina/White corundum (WA), and green silicon carbide/green carborundum (GC).

Check below to see the standard specifications for vitrified mounted points.

Shape Types

Below is the precise description of the three shape types of vitrified mounted points that could help choose the perfect shape:

1. “A” Shapes– These are perfect for metal fabrication plants with general maintenance applications.
2. “B” Shapes– These are designed for light deburring of machined parts. They can also work for surface finishing or polishing molds and dies.
3. “W” Shapes– These are the standard shapes ideal for precision grinding, particularly for machined parts, dies, and molds. They involve medium to heavy stock removal.

Detailed Description

Vitrified mounted points are often used in the foundry and precision engineering workshops. They help effectively with deburring and cleaning castings and machined parts. They can be seen in different shapes and two specific abrasive types. These types include silicon carbide and aluminum oxide. Check below for detail.

Silicon Carbide Vitrified Mounted Points

Silicon carbide vitrified mounted points are designed for grinding, cutting, and honing non-metallic material, non-ferrous steel, cast iron, brittle & hard carbide, stone, gem, and glass. They are grouped into green silicon carbide and black silicon carbide mounted points.

Applications Silicon Carbide Vitrified Mounted Points

The standard applications of vitrified mounted points are internal grinding, blending contours, deburring molded components, offhand bench grinding, mold finishing, and tool/die. They are widely applied because they come from medium to hard points.

Silicon carbide vitrified mounted points are used for

• Surface Grinding
• Edge Grinding
• Cutting/ Honing
• Surface Finishing

Features of Silicon Carbide Vitrified Mounted Points

• Features a fast-cutting abrasive performance, ideal for non-ferrous metals and low-pressure conditions.
• Harder and sharper grain type than aluminum oxide
• Great for finishing
• Easy application for cutting plastic, glass, and metal materials

Aluminum Oxide Vitrified Mounted Points

Aluminum oxide vitrified mounted points are designed for industrial use because they are applied on painted surfaces, bare wood, and metal. They are more durable than silicon carbide materials. They are grouped into pink & white aluminum oxide and brown aluminum oxide. The pink and white aluminum oxide provides starker contrast than brown aluminum oxide, and it can break down quicker than its brown counterpart. The brown, on the other hand, is the most common form and can offer longer service life because of grains that crack and break down slower than its pink & white counterpart.

Applications of Aluminum Oxide Vitrified Mounted Points

Aluminum oxide vitrified mounted points are used frequently in several industries because they are durable.  Below are some of their applications:

• External and internal bearing and grinding
• General-purpose stock removal to light deburring
• Used on die in-line/straight shank grinders
• Aerospace components and medical implants.

Features of Aluminum Oxide Vitrified Mounted Points

• Wear-resistant with longer work-life
• Low-maintenance cost and excellent shelf life
• Highly efficient and durable

Applications of Vitrified Mounted Points: Industrial Fields and Areas

Several industries use vitrified mounted points for various applications. Some of these industrial fields and areas include:

• Foundries
• Metal fabrication or welding
• Aerospace
• Medical industry
• Automobile
• Manufacturing industry
• Energy & environment field
• Collision repair

Choosing the Most Suitable Vitrified Mounted Points for your application

Below are five steps on how to choose the best abrasive for a deburring and edge-breaking process:

1. Select the grain type: Aluminum oxide vitrified mounted points are a grain type that offers a brighter and high purity surface finish. Their grain is versatile and features a specialty bond.
2. Select the proper bond: Hard bonds are perfect for softer materials, while soft bonds are ideal for hard materials. This should guide you when choosing the perfect bond.
3. Select the grit size: The grit size determines the amount of metal that must be removed. The rougher the grain, the lower the grit level. Rougher grit will be preferable for faster stock removal. But a finer grit will be better for light recurring, blending, edge breaking.
4. Choose the proper shape: Choosing the right shape will help with burring and getting sharp edges. The available shapes with different applications include A, B, and W.
5. Check the operating speed: You should ensure that the operating speed of your tool is properly checked before the use of vitrified mounted points – it mustn’t exceed its maximum for the safety of everyone and prevent the tool from wearing out. Besides, a higher speed may reduce the point’s life and decrease the deburring quality. You may check the speed chart that comes with the shipment for the standard and average operating speeds.

Notes:

• Follow the steps and try them in actual processing. If it fails, take note of where the process goes wrong.
• Remember that finer grit is perfect for a rough surface finish and a harder bond for mounted points for removing too much metal.
• Vitrified CBN mounted points wheels can also be used for the internal grinding of metal steel. You may click here to view the product page.
