Hey Guys,
I purchased some used Sandvik hydro grip toolholders, with tools already in them, and I'm having trouble removing the tools from a few of them. These are the older hydro grip holders that use a separate clamping device that you have to pump by hand. Very little information is available about these toolholders and were replaced by a newer design which uses only a screw on the side of the toolholder to pressurize fluid for clamping.
The clamping unit I have has a toggle valve with three positions (A/Pressure release/B). A is meant for clamping tools and goes up to 500psi. B goes up to 800psi and is meant for unclamping. The center position for the valve is the pressure release.
I have a feeling the stuck holder were mistakenly clamped with the valve on the B position at the higher pressure. Is anyone familiar with these toolholders and know of a way to unclamp tools that may have been incorrectly clamped?
Thanks in advance for any help.
