The tool for the machining of bores with 68-110 mm diameter. STANDARDIZED PRECISION The newly developed multiple-stone PT tooling system is designed for honing bores with a diameter range of 68–110 mm. A special feature is the re-structured modular system, which is characterized by the utilization of standardized components. YOUR BENEFITS In addition to the technical and application-related advantages, the modular structure of the tooling system enables the best delivery times both for new tools and tooling rework. A high degree of standardization results in reduced production costs - an additional customer benefit with respect to economy in the application.
