I have a Chinese 9kW ISO30 ATC spindle on my router and a linear tool rack with ISO30 forks to place the tools into.

However, when the drawbar is released the tool is pushed about 2.5 mm out of the spindle head. This causes the tool fork to deflect a lot when I put a tool back into the fork. And the same when I'm picking a tool I need to place the spindle 2.5mm above the tool, and the tool fork deflects upwards as the drawbar is closing on the tool. All in all, this puts a lot of stress on the tool forks and the z-axis assembly. So my questions is:

1. Is this design usual for most spindles, or could it be that I'm using the wrong type of pull studs on my tool holders?
2. Are there other forks out there that have built-in play in the vertical direction for the tool to travel up and down in the fork as the tool is being released / held?
