The FAPI–PA GEFRÄST contact disc is an extension of the smooth version. Here, grooves are milled into the NBR covering. The grooves can be made into the covering with a wide variety of widths, depths and angles.
The total height of the covering can also be selected variably, with the standard height proven in practice being 20 mm. The higher the covering, the more elastic and therefore softer the contact disk surface appears.
Due to the milled grooves, the contact disks are much more aggressive than smooth contact disks. The aggressive effect of the contact disk can be optimized for each application through an optimal ratio of groove and web width so that high-performance processes are possible. This contact disc also impresses with its longevity.The contact disks of the FAPI-PA series are exclusively provided with an NBR coating. In practice, the contact disks coated with the material NBR are often simply called “contact disks with a rubber coating” or rubber contact disks.Advantages of contact discs with NBR coating:
- Longest service life
- Wear resistance
- Oil resistance
- Grease resistance
- Emulsion resistance
Due to these outstanding properties, the contact discs of the FAPI-PA series have proven themselves on the market for decades.Contact disks FAPI-PA GEFRÄST are the standard contact disks often found on machines. Due to the universal application possibilities, almost all machine manufacturers supply their machines with contact disks from this series.Grinding operation: Cylindrical grinding, surface grinding, the most difficult grinding and roughing work
Grinding type: wet and dry grinding processes
Handling: Automatic grinding, hand-held machines, hand grinding bench/backstand, robot grindingDiameter: 75 to 450 mm
Width: 20 to 200 mm
Bore: according to specifications
Further dimensions on request!The hardness of the NBR coating can be divided into five levels. The spectrum here ranges from an extra soft NBR covering with 35º Shore (A) to an extra hard NBR covering with 90º Shore (A).The correct selection of the design and contact disk hardness always depends on the individual application.Contact disks FAPI-PA GEFRÄST are the standard contact disks often found on machines.
