[Processing Example] Die General-purpose Grinding Machine CNC Internal Grinding Machine STG-6N

[Processing Example] Die General-purpose Grinding Machine CNC Internal Grinding Machine STG-6N

Achieving roundness of 0.8μm or less! Here are examples of cases where we proposed our spindles.

We would like to introduce a case study of "dice" processing that we conducted. In the customer's equipment, increasing the spindle rotation speed led to unstable precision, creating distrust in the spindle. Therefore, we proposed that our spindle maintains stable precision even at maximum rotation speed. Compared to before implementation, we achieved a 50% reduction in processing time and roundness of less than 1.0μm. 【Case Overview】 ■Processing dimensions: φ7.8mm×7mm ■Material: Carbide ■Features: Special outer diameter ■Model: STG-6N ■Spindle: SSPG-045 T100 (Max 45,000rpm) *For more details, please refer to the related links or feel free to contact us.

Hybrid Precision Internal Grinding Machine IIG-20H

Hybrid Precision Internal Grinding Machine IIG-20H

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.
