»venturion« Increases Accuracy and Process-Reliability

Remarkable Time Savings mean More Efficiency
Korin Iron Works, based in the Hokuriku region, specializes in manufacturing high-value parts on state-of-the-art machining centers, including turbine blades for the aerospace industry and power generation equipment. In response to intensifying market competition and increasing quality demands from customers, Korin considered a fundamental reform of their production processes. Specifically, there was an urgent need to improve various stages of the production process, including further enhancing and stabilizing processing quality, preventing unexpected quality issues, significantly reducing tool setup time, and improving workability by reducing operator burden. To comprehensively address these challenges, Korin decided to implement ZOLLER’s latest tool measuring machine, the »venturion«.

Defect Reduction

With the introduction of the »venturion« presetter, processing accuracy improved dramatically, successfully reducing the number of defective products from several per month to zero. This improvement not only decreased the number of defects but also led to the reduction of various hidden costs, including additional material costs for rework, overtime pay for workers, and disposal costs for defective products. Specifically, cost reductions exceeding 20 thousand Euro (EUR 20,000) per month on average have been achieved and maintained for about a year. This result directly contributes to improved production efficiency and cost reduction, significantly enhancing customer satisfaction and substantially strengthening Korin’s market competitiveness.

Precision Improvement

Even in an environment with unavoidable temperature fluctuations within the factory, the »venturion« enabled measurements with extremely small variations of 5 microns in the axial direction. This high-precision measurement made it possible to achieve single-pass machining precision, which was previously difficult. This has led to the prospect of significantly reducing the finishing process that was necessary before, resulting in shorter processing times and reduced material waste.

Productivity Enhancement

The realization of single-pass machining is expected to reduce setup time by 20–30%. Although this has not been fully achieved at present, recent trial efforts have sufficiently confirmed its possibility. In the near future, when this single-pass machining is fully implemented, it will eliminate the need for the conventional “rough machining” and subsequent “finishing machining” processes, leading to a significant increase in productivity. This is a crucial improvement that directly leads to shorter production lead times and expanded production capacity.

Time Savings

The change in tool measurement time after the introduction of ZOLLER’s »venturion« premium presetter has been remarkable. Currently, about 150 tools are measured monthly, and the tool setup time has been successfully reduced by about 70 % compared to before implementation. Furthermore, there is strong confidence that as operational proficiency increases, the current work time can be further halved in the coming fiscal year. This significant time reduction directly contributes to the efficiency of the production line, clearly demonstrating the high efficiency and investment effect of the »venturion« from ZOLLER.

Versatility

The introduction of »venturion« has made it possible to simultaneously measure not only the length and diameter of tools but also angles and corner radii for tools with complex shapes. This versatility has enabled effective prevention of unexpected quality issues in the manufacturing process. In particular, the ability to accurately measure precision tools such as reamers and boring bars has significantly reduced unnecessary machine downtime. Additionally, the setup time for milling cutters has been greatly reduced, as measurements can be made easily, quickly, and with high precision using the »venturion«. By leveraging this versatility, both productivity improvement and quality stabilization have been achieved simultaneously.
