Isotropic Superfinishing is used to produce a high quality
surface finish to components. Typically used on components where high
contact stresses are present. The improvements in surface finish gained
by superfinishing can reduce wear, reduce stress concentrations and
improve overall finish whilst extending component life.
Wherever metals come into contact with each other then
contact stresses and friction occur.
Both these conditions regulate and reduce the performance and compromise
the design of the component.
Superfinishing is a means of regaining those losses by producing a
superfine finish where it is most needed- at the point of contact.
The benefits are greatest with high contact stress applications and high
fatigue life requirements. It is particularly beneficial in mating gear
applications where it is proven to reduce contact stresses but also to
reduce individual tooth bending which is key to maintaining good fatigue
life with a resultant reduced operating temperature.
Whilst it is known that reduced operating temperatures are an indication
of increased performance the secondary benefit is that there is less
heat to dissipate and as such the specific cooling cross section or
cooling flow rate can be reduced which all compliment efficiency and
performance.
