brunel xf 527

Q8 Brunel XF 527 is an advanced non-cobalt leaching synthetic grinding fluid for all hard metals grinding operations, including all surface grinding, cylindrical grinding, as well as tool and cutter grinding. It is developed to give the highest quality finish in all operations. When diluted with water it forms a true solution rather than an emulsion, which gives excellent wheel and workpiece visibility. Q8 Brunel XF 527 uses the latest full synthetic anti-corrosion additive technologies. It provides outstanding corrosion protection, suitable for stainfree machining of ferrous metals.

  • Q8 Brunel XF 527 is recommended for all hard metals (e.g. tungsten carbide) grinding operations including all surface grinding, cylindrical (internal and external) grinding, as well as tool and cutter grinding. It is particularly recommended for creep feed and centreless operations. It is not however, suitable for grinding alloys containing zinc or magnesium.
