accurate to 75 microns and about 0.05 degrees in orientation.  The A variant of HSK tooling has a gap of 330 microns and has  a rotation of about 0.5 degrees and because of this, the turning  tools are not correctly oriented during tool changes.  For these reasons, the A variant of the HSK standard is not  specified in the Technical Specifications and the current  specification remains unchanged.  Q23  Item 2.4.15  Machine shall have at least +/- 100 mm movement on the Y axis.

Therefor in order to reduce confusion and allow  various different manufacturers we kindly request you to update this requirement as  follows ;  “Machine shall have at least 200 mm movement on the Y axis covering both  directions.” Based on the comprehensive market research conducted,  requested technical specifications are available in more than one  eligible product. Therefore, the specifications remain unchanged.  Q24  Item 2.4.23  Machine shall have control panel with minimum 20-inch color touchscreen display  screen  According to our market research, this requirement greatly limit the possible  manufacturers which can comply with technical requirements. Therefor in order to  increase the number of possible manufacturers and increase the competition among  tenderers, we kindly request you to update this requirement as follows;  Please refer to Changes No:1 to the Tender Dossier, article  2.4.23.
