Precision Granite Triangular Component with Through Holes

●  High-density ZHHIMG® black granite

• Density around 3100 kg/m³, higher than common European and American black granite.

• Natural aging and ultra-low internal stress for excellent long-term stability.

• Non-magnetic, non-conductive, corrosion-resistant.

●  Superior dimensional accuracy

• Precision machining and manual lapping by craftsmen with 30+ years of experience.

• Surface flatness and parallelism can reach micron or even sub-micron level according to customer drawing.

• Edges and mounting faces are carefully chamfered to reduce damage during handling.

●  Perfectly matched precision holes

• Two through holes are machined in one setup to guarantee positional tolerance, roundness and perpendicularity.

• Suitable for alignment pins, air bearings, linear motors, bolts or dowel connections.

• Hole surfaces can be honed or lapped on request for higher accuracy.

●  Excellent vibration damping

• Granite has better vibration absorption than cast iron or steel.

• Reduces transmission of micro-vibration to sensitive optical, metrology or semiconductor processes.

●  Thermal stability

• Very low coefficient of thermal expansion and slow temperature response.

• Ideal for constant-temperature rooms and precision assembly environments.

●  Clean and maintenance-friendly

• Polished surface is easy to clean, does not rust and does not require painting or oiling.
