XPA metal conditioner anti-friction practical test

Test XPA your own way

An easy, quick and simple test which can be conducted in a machine shop to show the lubricating properties of XPA can be performed with a 14mm drill bit, 2 x 14mm pins and a drill press. Using a block of mild steel, drill a 14mm hole 17mm to 22mm deep, then replace the bit with one of the 14mm pins. The pin should turn freely in the hole. Add several drops of lubricating oil to the hole, run the pin into the hole with the drill operating at a medium speed. The pin will "weld" into the hole in a matter of a few seconds. Then take the stock and drill a second 14mm hole, chuck up the second pin and this time use XPA in the hole. When you apply the pressure, do it gradually to allow the XPA to treat the pin, then you can run the pin for several minutes if you like without the tendency to "weld". The demonstration really shows how XPA stands up to extreme pressure and heat
