Neptune – Automatic back spot facing tool

The waterdriven back spot facing tool developed by Granlund Tools

With the Neptune back spot facing tool you can produce spotfaces of up to 2 times the diameter of the entry hole. As special, the tool can be manufactured for an even wider range.

Neptune is powered by coolant through the spindle. It operates using a piston in the shank, which pushes the insert cartridge out. The Neptune is a combination tool, where you can strip and clean the parts, change insert holder for another dimension etc.

The tool is also equippe with an “emergency” function. The shank seperates from the holder in case the insert cartridge doesn’t retract properly. The spindle needs to be reversed during retraction after the spotfacing to ensure that the emergency function operates proprely.

All friction parts are coated with a low friction coating to ensure the function of the tool.
