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.
