Why Flex-Hone?

Simply because you'll increase the service life of many pieces of equipment by very worthwhile amounts. For instance  customers report  such things as double life between heat exchanger cleaning - up to 9 times the life of hydraulic seals and in race car engines  - far less downtime etc., etc.


How does Flex-Hone offer these gains?

Well, let's explain . . . when you finish by using Flex-Hones you produce a more frictionless surface than you could create with any other tool and by doing this you prevent premature wear in any mating parts like piston rings and seals. And in heat exchanger tubes you produce a finish that's actually better than new . That's why you get such radical improvement in the service life and performance of equipment.


And why you gain these advantages is because Flex-Hones use a totally different method of metal finishing to  any other machining or surface treatment process. We call it "downwards" finishing. Almost all other types of  metal processing use "upwards" cutting. Let's explain . . . cutting  tools of any type must penetrate below the surface and lift material up and off the workpiece. Ordinary abrasives  do exactly the same thing because they're just like thousands of miniature cutting tools. This always leaves a jagged finish even if it's so minute you can't see the sharp peaks (see Diagram #1 and the corresponding roughness readout at right).On the other hand Flex-Hones rub from the top of the work surface and smooth the jagged peaks downwards leaving a "plateaued" or flatter finish without jagged peaks (See Diagram #2 and the corresponding  roughness readout).
