How Vacuum Brazed Diamond Grinding Discs Control Heat When Grinding Cast Iron
Vacuum brazed diamond grinding dsics Grinding cast iron is always a thermal challenge. Excessive heat can cause surface discoloration, microcracks, accelerated tool wear, and operator discomfort. Compared with conventional abrasives, vacuum brazed diamond grinding discs are increasingly chosen for cast iron finishing and deburring—not only for speed, but also for their superior heat behavior . This article explains why vacuum brazed diamond discs generate less harmful heat , how they compare with other bond types, and what this means in real cast iron applications. Why Heat Control Matters in Cast Iron Grinding Cast iron has unique properties that influence heat generation: High carbon content leads to brittle chip formation Poor ductility increases friction during grinding Localized heat can cause surface glazing or micro-fracturing Excess heat accelerates diamond degradation and wheel loading Controlling temperature at the grinding interface is critical for b...
