Union Ceramics take pride in its outstanding wear resistance and thermal shock resistance with high
turning speed cutting. Pure raw materials give stability and fine microstructure to the products. turning
& Through HIP process, shaped bodies are completely condensed so that the finished goods are strong &
Milling and resistant against fracture and wear. Milling
• Improved work efficiency by increasing cutting speed on extremely higher than carbide inserts.
Application Range • Longer tool life through excellent wear resistance
• Precise cutting and superior surface roughness
