Technical information

Mounted flap wheel set aluminium oxide dia. 20x10 mm shank dia. 3 mm A 80, 120 and 180 for fine grinding & finishing

PFERD type: SET F 2010/3 A
Packaging unit: 1 piece

Description

PFERD offers a wide selection of coated abrasive tools for working on different workpiece geometries and materials. They consist of a base, a base bond and a coating bond for the abrasive grain to adhere to. Depending on the grit size, coated abrasive tools can achieve a high stock removal rate or a very fine surface finish.

The available backing materials differ in properties such as tear strength, flexibility and wear. With the right base, the grinding tool is adapted to the requirements of the intended application: paper is used in the woodworking industry and in trade, e.g. among carpenters, painters and decorators, cloth is predominantly used for metalwork, and vulcanized fibre is highly wear-resistant and is used in various thicknesses predominantly for making fibre discs.

The set contains three mounted flap wheels in the aluminium oxide A type with a shank diameter of 3 mm in grit sizes 80, 120 and 180.

On mounted flap wheels, the flaps made of coated abrasive are arranged radially around the tool axis in a fan-type structure. Their flexibility enables them to adapt perfectly to the contours of the workpiece. The abrasive grain is embedded in the sturdy, flexible cloth backing material by means of a resinoid bond.

Advantages

Highly flexible, enabling optimal adjustment to the contour.
Consistently high stock removal rate over the entire tool life as new, aggressive abrasive is constantly exposed.
Can be used face-down very close to edges and in corners thanks to the flat, moulded-core design.
For getting to know and testing the comprehensive range.
Coordinated selection of the most common grit sizes.

Recommendations for use

Reducing the contact pressure and the peripheral speed and adding grinding oil diminishes tool wear and thermal load on the workpiece.
To increase the stock removal rate, it is advisable to use a coarser type of grit instead of increasing the contact pressure. This will prevent unnecessary tool wear and thermal load on the workpiece.
The increase in cutting speed leads to a slightly finer surface quality. Increasing the contact pressure makes the surface slightly coarser. The softer the material that is being worked on, the coarser the surface (when using the same grit size).
For the best results, use at a recommended cutting speed of 15-20 m/s. This provides an ideal compromise between stock removal rate, surface quality, thermal load on the workpiece and tool wear.
Use grinding oil that is suitable for the material in order to significantly increase the tool life and the abrasive performance of the tools.

Safety notes

For safety reasons, the maximum permitted rotational speed indicated must never be exceeded.
The contact pressure must be significantly reduced if the specified optimum rotational speed is exceeded.
Safety can only be guaranteed if the clamping length is at least 15 mm and the specified maximum rotational speed is not exceeded with unsupported shank lengths.
