What Is a Mounted Point?
A mounted point is a type of grinding tool with a spindle, primarily used in metalworking for grinding, polishing, chamfering, and rust removal. It comes in various materials and hardnesses, typically featuring abrasives like alumina, silicon carbide, and ceramics.
Applications of Mounted Points
Mounted points are essential for precision polishing in automotive, electronics, and mechanical parts production. They excel in localized or deep polishing tasks that are challenging with standard polishing equipment, also aiding in rust and debris removal.
Features of Mounted Points
Advantages
These tools offer precise alignment between the grinding surface and spindle, ensuring high-precision grinding and stability. Their direct attachment to the spindle enhances durability and efficiency, allowing for rapid and accurate grinding without excessive wear.
Disadvantages
Their use is limited by the spindle size, and large diameters can cause abrasive grains to detach if spun too quickly, necessitating lower speeds. Installation can be time-consuming, and improper setup may pose safety risks.
Using Mounted Points
The process involves selecting the appropriate grindstone, adjusting the grinding position, setting the rotation, performing the grind, and applying coolants or lubricants to manage heat and remove debris.
Types of Mounted Points
Mounted points are categorized by shape, abrasive material, and binder type. Alumina is used for hard materials, silicon carbide for steel and stainless steel, and other materials like boron nitride and diamond offer high hardness for specialized applications.
Other Information
Bonding Agents for Mounted Points
The performance and application of mounted points vary with the bonding agent—metal, ceramic, or resin—each offering different levels of bonding strength, heat resistance, and suitability for polishing or high-speed machining.
