The FAPI–PA MILLED FREQUENCY DAMPED contact disc is the further development of the milled version. Grooves with a groove width-groove depth-web width ratio specially developed by us are milled into the NBR coating of the contact disk. This means that – during the belt grinding process – both the noise level is reduced to a minimum and the material removal rate is increased to a maximum.
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.
The contact disks are very aggressive when used due to the grooves they contain. The aggressiveness effect of the contact disk can also be optimized for each application with the milled frequency-damped contact disk by means of an individually optimized groove width-groove depth-web width ratio. Like all contact discs in the PA series, this version 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 MILLED FREQUENCY DAMPED 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: dry grinding process
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 MILLED FREQUENCY DAMPED are the standard contact disks often found on machines.
