The FAPI-BW contact disk is covered with cotton fabric lamellas around the aluminum core. The height of the covering or the length of the cotton fabric slats can be selected variably depending on the application (standard: 35 mm).

By covering it with cotton fabric lamellas, the contact disk is given a “running cushion” that allows for (very) fine grinding, especially on (strongly) curved and profiled parts.

The covering adapts easily to any workpiece to be sanded. In particular, the softer coating design of the FAPI-BW contact wheel contributes significantly to the cooling of the sanding belt, as the heat from the belt grinding process is dissipated through the spaces between the lamellas.The contact discs of the FAPI-BW series are very suitable for fine grinding thanks to their construction with lamellae made of cotton fabric.Advantages of contact discs with slats made of cotton fabric:

  • Highly elastic (adaptable)
  • Wear-resistant

Due to these outstanding properties, the contact discs of the FAPI-BW series have proven themselves on the market for decades.The FAPI-BW contact wheel is used for heavily profiled or heavily rounded parts that are manually sanded using dry grinding.Grinding operation: round grinding, profile grinding

Grinding type: dry grinding process

Handling: Automatic grinding, hand-held machines, hand grinding bench/backstand, robot grindingDiameter: 75 to 450 mm
Width: 20 to 200 mm
Slat height: 35 mm / according to specifications
Bore: according to specifications

Further dimensions on request!The hardness of the contact discs with slats made of cotton fabric can be differentiated in several levels. The spectrum here ranges from an “extra soft” to an “extra hard” surface. This hardness of the FAPI-BW contact disk is achieved via the number of cotton fabric lamellas on the circumference of the contact disk, i.e. the density of the cotton fabric lamellas. Unfortunately, an exact specification in Shore (A) is not possible.
