meets the requirements of flexible production Uniformity, performance and flexibility are the prominent features of the new turret interface pti (polygonal turning interface). As a unified mechanical interface, this solution provides the preconditions for the flexible equipment of modern turning machines with precise, high-performance tool holders and driven tools. The media supply (coolant, air) and the data and energy transfer complete the pti interface. Merkmale Positive locking (polygon) • torsional rigid Data and power transmission • equipped for i4.0 Face contact and clamping system •...

Leading-edge technologies united in pti-interface WTO – holds tight precisely and rotates WTO has developed toolholders with the new pti interface and introduces a program for static tool holders and driven tools in the pti-sizes. Based on the design of the interface polygon, the pti shank and holder body form a precise unit with all the necessary elements for mechanical power transmission and media supply. The tool receivers of the precision tool holders are matched to the pti sizes and make the outstanding performance of the pti interface technologically feasible at the cutting edge....

Sauter – receives and drives Sauter has designed the pti radial turret with a front cover which allows easy mounting of the pti clamping system. The compact design results in a width across flats of only 340 mm for pti65 with a 12-fold turret disc. The turret construction allows both the use of Speed-Drive® and Torque-Drive® technology. Despite the installation of the components in a confined space, a stable turret design has been created, with which the performance of the pti interface can be implemented to 100%. All pathways required for the media supply are integrated as well. A strong...

Industry 4.0 development requires an integral view of flexible production systems. The design of uniform mechanical interfaces is just as necessary as the definition of uniform interfaces for the collection and processing of data in the course of digitisation. With the pti interface for tool turrets in turning machines, the pti-working group creates the preconditions for limiting the variety of mechanical tool interfaces and contributes to designing flexible production systems according to requirements. The pti-working group has developed an interface in which mechanics and media supply are...

„Standardization of a uniform coupling for driven tools in turret lathes“ Project REKUNORM • The funding project REKUNORM closes the last gap in the design of the new turret interface. • Ott-Jakob, Sauter, Weisser, WTO and the WZL are developing a uniform DTH coupling for axial and radial applications. • Further tasks in the project are: • Development of the model series (pti 65, 54, 42). • Definition of interfaces for media / energy / data transfer (cooling lubricant, sealing air, electrical contacts). • Series testing in the experimental machine and in the industrial environment. •...

pti-working group Proposed standard After completing the most important development stages of the pti interface, defining a series and demonstrating the performance, the pti-working group has developed a proposal for a standard. The three-part proposal includes the tool shanks (part 1), the tool receivers (part 2) and the couplings for driven tools (part 3). The proposed standard will be submitted in two stages (parts 1 and 2 in 2018, part 3 in 2019) and, with the support of the DIN and VDW committees, transferred directly to a DIN standard. The pti-working group has developed three sizes...
