The debut of the 【Hybrid Precision Internal Grinding Machine IIG-20H】, which offers versatile usability and efficient grinding comparable to NC machines.
By incorporating Renishaw's absolute scale and solenoid valve into Mitsubishi Electric's touch panel sequencer control, we have achieved ultra-high precision with roundness of 0.3µm to 0.4µm, while maintaining the advantages of general-purpose operation with handles and levers. This allows for digital representation of positional relationships equivalent to NC machines, reducing the burden on operators and enabling efficient high-precision grinding.
Previously, real-time numerical data could not be viewed, and adjustments relied on the craftsman's tactile sense, with measurements taken after polishing to determine values.
The hybrid precision internal grinding machine IIG-20H offers significant improvements compared to the existing YIG model:
- In a standard grinding process, the total time has been reduced by 75 seconds out of 210 seconds (35% time reduction).
- Additionally, in setup, a time reduction of 143 seconds out of 180 seconds is possible (79% time reduction).
- For difficult-to-cut materials, the dressing interruption function further shortens grinding time.
This hybrid precision internal grinding machine meets customer needs for precision grinding and production efficiency.
