Korin Iron Works, based in the Hokuriku region of Japan, specializes in manufacturing high-quality parts on state-of-the-art machining centers, including turbine blades for the aerospace industry and power generation plants. In response to increasing competition in the market and the rising quality demands of customers, Korin considered a fundamental reform of its production processes.

In particular, there was an urgent need to improve various stages of the production process, including stabilizing processing quality, avoiding unexpected quality problems, significantly reducing tool setup time, and reducing operator workload.
To address these challenges comprehensively, Korin decided to introduce the ZOLLER »venturion«, the premium system for professional tool presetting and measurement.
Reducing errors
With the introduction of the »venturion« presetting machine, processing accuracy improved significantly, reducing the number of defective products from several per month to zero. This also led to the reduction of various hidden costs, including additional material costs for reworking, overtime payments for workers, and disposal costs for defective products. Specifically, cost reductions averaging over €20,000 per month were achieved and maintained over a period of approximately one year.
Improving precision
Even in an environment with unavoidable temperature fluctuations in the factory, »venturion« enabled measurements with extremely small deviations of 5 micrometers in the axial direction. This has made it possible to achieve a level of precision in single-pass machining that was previously difficult to achieve.
It has opened up the prospect of significantly shortening the previously required finishing process, resulting in shorter machining times and less material waste overall.
Saving time
The change in tool measuring time after introducing ZOLLER's premium »venturion« tool presetter is remarkable. Currently, around 150 tools are measured each month and tool set-up time has been reduced by around 70%, and the company is confident that the current working time can be almost halved in the coming financial year as user competence increases.
This considerable time saving contributes directly to the efficiency of the production line and clearly demonstrates the high efficiency and positive investment effect of the »venturion« from ZOLLER.
Driving consistently positive results
One year after implementation, ZOLLER »venturion« continues to help meet the daily challenges of production operations and is a reliable partner for Korin.
Based on this successful experience, Korin is now taking up the challenge of even more advanced manufacturing technology aimed at the complete machining of precision parts in a single pass. The introduction of the ZOLLER »venturion« is more than just an investment in equipment for Korin; it represents an innovation in their manufacturing process and an investment in the future.
