Master gears are used in single and Double Flank Gear Inspection and
Rack Inspection Machines as test gears.
Several types of steel are available as base material for master gears. Wear resistance increases from gauge steel LS to chrome steel CS and finally to powder metallurgy high speed steel SX. In addition, coatings protect the surface against wear and corrosion.
