Microfinishing Film is one of the most extended and varied product family within the Precision Polishing microabrasive films products range.
Especially since the recent introduction of Diamond Microfinishing Film FD55, this group of products offers to the end-users one of the most complete portfolios available on the international markets.
For this reason, we decide to dedicate this article to give a complete and clear overview of this fundamental product range.
Concerning common features along the microfinishing films product range, the grit deposition technology is surely the most relevant: the electrostatic coating.
During this coating process the abrasive grains are electrostatically oriented and fixed between 2 layers of resin (base coat and top coat) to the PET backing film giving the following main advantages:
Another common point is that all Microfinishing Film products are back printed in order to easily identify the required grit.
This is a substantial difference with the Polishing or Lapping film, where differentiation between grits / products occurs exclusively thanks to color-coding.
Especially concerning the back printing of FA50 and FS50 Microfinishing Film series, Precision Polishing adopts a unique system of inclined printing (not parallel to the roll direction) made of lines and alpha-numeric characters.
This system has been developed especially thinking to customers that work with narrow slitted rolls (mostly required in the powertrain industry) because, seldom occurs, that roll brakes during the superfinishing processes. When this happen, the user must manually joint the 2 broke sides of the roll in order to start again the working process. During this joint operation is essential to not mix up the abrasive side with back side of the broken tape! It could happen especially we medium-fine grits are used where the feeling of the fingers could be misled!
The below image shows how our back-printing structure helps to avoid this inconvenience!
