Product Description of the Klingspor FS 764 Aluminium Oxide Fibre Discs Star-Shaped Centre Hole
The Klingspor FS 764 ACT aluminium oxide star shaped fibre discs is a fibre disc that has been designed specifically for use on steel and stainless steel. This fibre disc allows for grinding operations with a high removal rate. The abrasive used is aluminium oxide. The bond formulated from Klingspor’s special ACT recipe provides for high grit adhesion.Advantages:
Rough and aggressive grinding with the fibre disc FS 764 ACT
The robust combination of backing, bond, and grit translates to aggressive abrasive performance when grinding metal or removing rust from metal parts and during rough grinding, smoothing weld seams, and deburring. Keeping the tool from exceeding the maximum permissible speed of 80 metres per second requires that the maximum speeds for specific disc / backing pad diameters be observed:
Use of the fibre disc FS 764 ACT
The fibre disc FS 764 ACT is available in grit sizes ranging from coarse to fine. This makes the fibre disc FS 764 ACT suited primarily for use cases requiring a high removal rate and aggressive abrasive performance.
The scratch pattern you want to achieve largely depends on the backing pad you use
Klingspor’s portfolio includes two different backing pads for fibre discs: the backing pad ST 358 medium and smooth as well as the ST 358 A hard and ribbed. The scratch pattern is defined in no small part by the choice of backing pad. The medium backing pad is recommended for producing a uniform scratch pattern, e.g. when rounding sharp edges or creating a finer finish on metal surfaces. In contrast, the hard and ribbed backing pad is used for rough and aggressive grinding, as is necessary, for instance, for edge chamfering or rough deburring jobs.
