PT Series tooling system

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 and an easy tool management - an additional customer benefit with respect to economy in the application.

Technical highlights

The so-called tool string consists of the honing tool and the connecting piece for the spindle. The revision of the joint kinematics in the tool string as a whole – in particular the integration of the lower joint into the honing tool – leads to an ideal compensation of the angular deviation and offset of the workpiece bore to the machine spindle. The adjustability of the joints ensures an extremely long life.

The newly designed air and coolant supply of the tool string enables optimal cooling on the area being worked on as well as an in-process gauging in two levels. These technical feature ensure that machining tasks meet the quality requirements for shape and dimensional tolerances of 5–10 μm. This applies to all industry-standard surface requirements of our customers.

Typical areas of application

Applications for the PT Series are cylinder crank cases in diverse models.

Tooling Rework

Continuous professional tooling rework increases the life cycle of your honing tools and guarantees optimal process reliability.
Reduce your tooling costs by preventive maintenance and profit from our experience.

Whether Gehring or third party - we will rework your honing tools back to optimal condition. Your benefits are obvious.

Abrasives

The Diato honing stones which are also a product of the Gehring Group, have abrasives made from synthetic diamond or cubic boron nitride (cBN). These abrasive crystals are embedded in a hard metallic matrix. The grit size is then responsible for the stock removal of the material.
