EXO FEATURES
• A proprietary inter-metallic nickel based coatings technology.
• Under development over the past 6 years - $50m in investment.
• Unique combination of properties ideally suited for cutting and wear-

EXO TECHNOLOGY PROCESS LINE
NOT A LINE-OF-SIGHT PROCESS• Complicated geometry components can be coated with a uniform coating
thickness. No edge build-up.• Through holes and cavities can be coated to a tight tolerance finish.

WIDE RANGE OF COATING THICKNESS POSSIBLE• Depending upon application – typical 10 microns (0.0004 in.) to 100
(0.004 in.) microns. Possible: 800 microns (0.032 in.)• If coating is used in a sacrificial mode, there is substantial thickness to
wear through – so a prolonged component life is possible.

LOW COEF. OF FRICTION / HIGH LUBRICITY• The material has inherently low coefficient of friction. This property
coupled with the unique surface topography, gives coated surfaces a high degree of lubricity, making them ideally suited for SLIDING / ADHESIVE WEAR & GALLING application.

Conclusions of recent external testing
Tool temperature - reduced by 40 degrees
Horse-Power draw - reduced by 49%
CNC Cutting loads – reduced by 30-39%
Accelerated Acid Wear Test – wear reduction of 50%
EXO saws generate lower cutting forces vs uncoated saws. This translates into:
Lower HP draw
Lower tool temperature
Reduction of friction due to EXO provides reduction of heat, drag and wear – significant value driver for a diverse range of wood and metal working products.

EXO treated tools dissipate heat more effectively – hence remain cooler over a longer period of time Improved mechanical stabilityLess resin or work-piece material build-up Improved cut qualityLower ‘operating’ kerf ~ Less cutting deviation
PROPERTIES OF
EXO treated tools and components
EXO treated tools and components have excellent lubricityMaterial has an inherently low coefficient of friction. Unique surface topography minimizes contact surface area and hence
leads to lower friction forces.Lesser heat generation than uncoated saws Lower cutting forces and power requirements reduced energy
consumptionSignificantly reduced lubrication consumption
