Precision / semicon grinding
What it is
Ultra-precision grinding and polishing for semiconductor wafers, optics, medical devices and aerospace components, where tolerances run to microns and surface finish is the specification
It uses super-abrasives and engineered slurries rather than conventional wheels
Impact on industries
- The highest-value application available, with pricing set by process capability rather than by abrasive content
- India's semiconductor fab and ATMP investments create a domestic customer base where none existed, alongside aerospace and medical devices
- Qualification into semiconductor supply chains is exacting and slow, and incumbents are established global specialists
- Volumes are small relative to industrial abrasives, so it lifts mix and credibility more than revenue in the near term
