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 digitization.
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 that matches mechanics and media supply and provides space for elements of data and energy transfer. Due to its outstanding performance the new, future-oriented interface is suitable for both in series production and for flexible parts production and is introduced in various areas of industry.
Initiated by the four protagonists of the pti-working-group, the pti interface is on its way into the market and will be standardized concurrently. Thus, it is open to all interested parties.
At the EMO Hannover 2019, the companies of the pti-working-group and the extended body of experts present the new turret interface PTI. Get important information from our specialists on a development that will make your lathe even more powerful. We show PTI products from the toolholder and driven tool to the turret with clamping system up to the complete machine tool. For the first time you can see the new PTI interface in a vertical turning center at the EMO (Rasoma, NSH-Group).
The companies of the pti-working-group submitted the PTI standard proposal to DIN in May 2019 following completion of various successfully completed research projects. The proposal comprises the three parts: shank (1), receiver (2) and coupling (3). The proposal was accepted on 06 June 2019 at a meeting of NA 121-02-05 AA “Toolholders and Machine / Tool Interface” (DIN) and NA 122-59-01 AA “Machine-Side Toolholder Interface” (VDW). At DIN, the standard proposal is now being converted into a first draft standard under the number DIN 69108. It is expected that the PTI standard will be completed by the end of 2020. For information, the standard proposals can be downloaded. It should be noted that changes are still possible during the standardization process.
