what is a segmented grinding wheel

A segmented grinding wheel is a specialized type of grinding wheel characterized by its unique construction of segmented abrasive sections. Unlike traditional grinding wheels that have a continuous abrasive rim, segmented grinding wheels consist of individual abrasive segments separated by gaps.

 

These segments can be various shapes, such as hexagon, pellets, and pie segments.

 

The construction of segmented grinding wheels typically involves mounting replaceable abrasive segments onto a holding body using mechanical connections (like clamping, screwing, or wedging structures) or bonding/gluing connections (such as resin-bonding or gluing methods). The segments are often made of materials like silicon carbide or ceramic/vitrified binder.

 

The design of segmented grinding wheels offers several advantages:

• Enhanced Cooling: The gaps between segments allow cooling fluids to access the grinding zone more effectively, helping manage temperature and prevent overheating.
• Efficient Material Removal: The segmented design enables effective material removal by using centrifugal force to expel debris and maintain a clean cutting area.
• Surface Protection: The reduced contact area minimizes the risk of surface damage, improving the lifespan of both the wheel and the workpiece.

 

 

 

Segmented grinding wheels are commonly used in applications such as:

• Vertical spindle surface grinding
• Rotary and reciprocating table surface grinding
• Heavy stock removal prior to fabrication or assembly
• Grinding large parts flat and parallel
• OD grinding in the oil and thermal spray industry
