Isotropic Super Finishing

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.
