Product Description

99.5% Al2O3 High Wearable Bobbin Corundum Plate Alumina Ceramic Custom-Made Industrial Ceramic

 

Corundum Plate Alumina Ceramic Custom-Made

In CNC machining and precision mechanical operations, wear and low hardness of positioning components lead to frequent replacements, reduced accuracy, and increased costs. It's time to upgrade to components that keep up with your high-demand workflows.
Our Alumina Ceramic Positioning Blocks (CNC Machined & Sintered) are engineered for extreme performance, boasting:
  • ✅ Superior wear resistance - outlasts metal parts by 5-10x in high-friction environments
  • ✅ Exceptional hardness (HRA ≥ 88) - maintains precision shape even under heavy loads
  • ✅ High-precision CNC machining - ensures tight tolerances for accurate positioning
  • ✅ Sintered for durability - stable performance in harsh industrial conditions
  • ✅ Ideal for cutting machinery, mechanical fixtures, and precision machining equipment
Reduce downtime, lower maintenance costs, and elevate machining accuracy with our industrial-grade ceramic parts. Custom sizes and specifications available to match your unique application.
