Finisher's Tech SF-4 Super Finisher101.6 mm (4.00 inch) wide 3M diamond strips will be required for the Finisher's Tech SF-4 Super Finishing Machine and 203.2 mm (8.00 inch) wide 3M strips will be required for the optional equipment (Finisher's Tech SF-8 Super Finisher Machine). The 3M strips can be ordered in various lengths.1219.2 mm (48.00 inch ) with a 609.6 mm (24.00 inch) leader and 609.6 mm (24.00 inch) tail is a standard length. The leader and tail portion is required to feed the strips through the super finisher.A good measure is to keep a few of the plastic spools the 3M strips are shipped on. This practice can reduce the machine setup time when switching 3M strip grades.HVOF Super Finishing Mechanically
Use the super finisher to lightly grind the component to the proper size and surface finish.Although finishing components to a specified size and surface finish using only a grinder is possible, a super finisher has three important purposes. First, the process will remove any blemishes or "striping" (barber poling) the belt grinder leaves on the component. This step will eliminate variations in finish due to lathe conditions and operator experience. Second, the process produces a slight crosshatch in the coating similar to the fine cracks which occur in plated surfaces. This finish is desirable to help lubricate seals and enhance seal life. The third purpose is to achieve a more polished surface appearance, which is similar to the finish produced by plating. A 20.0 µm (0.79 µin) film should be used for superfinishing.Note: Care must be taken to monitor final surface finish as belts wear.The super finisher should be mounted to the cross slide of a lathe. To save floor space and reduce capital investment, the super finisher can be combined with a rear-mounted belt grinder setup on one lathe. This arrangement will allow both operations to be performed on the same machine, avoiding excess material handling.HVOF coatings can be super finished at a rate of 12.7-38.1 µm (0.50-1.50 µin) per pass at a traverse rate of 0.64 m/min (25.0 in/min).Coolant with a rust and bacteria inhibitor is required for the HVOF super finishing operations. Hard water may require treatment, since minerals can interfere with rust inhibitors and other coolant additives. The coolant should be flooded into the contact area between the abrasive and the component. As contact pressures increase, the pressure of the coolant should be enough to assure that the abrasive and component are being cooled properly. To improve diamond
