High quality instrument for measuring the concentricity of the main axis. Key benefits - Provides precise, repeatable measurements of axis concentricity to support accurate alignment. - Improves setup and inspection efficiency with clear, easy-to-read results. - Durable construction designed for reliable performance in both workshop and production environments. Function - Measure the concentricity of the main axis. Performance and compatibility - High quality construction built for long-term use. - Compatible with standard measurement workflows in machining and assembly settings. - Compact design facilitates handling and integration into existing fixtures and workstations. Use scenarios - CNC milling machine setup: verify spindle axis concentricity before starting high-precision milling operations. - Shaft and pulley assembly: check concentricity of a main shaft relative to mounting features during assembly. - Quality control: inspect finished shafts or spindles to confirm concentricity within specified tolerances.
