Description

Pferd Unmounted Flap Wheel

Flap Wheel - Unmounted Type - Aluminium Oxide
The coated abrasive flaps are arranged radially around the tool axis in a fan-type configuration.
Due to their flexibility, they adapt ideally to the contours of the workpiece. The abrasive grit is embedded in a resinoid bond on the strong, flexible backing cloth. Unmounted flap wheels are designated "Flap Wheels" according to ISO 5429.
For universal applications from coarse to fine grinding.

Recommendations for use

Unmounted flap wheels achieve their best performance at a recommended cutting speed of 30 m/s. This provides an ideal compromise between stock removal, surface quality, thermal load on the workpiece and tool wear.
Flexible shafts, straight grinders and grinding blocks can be used as tool drives
The drive power output required for tool drives is 1,000Ì1,500 watts
Use grinding oil that is suitable for the material in order to significantly increase the tool life and the abrasive performance of the tools.

Advantages

High flexibility
High stock removal due to the aggressive coated abrasive
Carrier material wears off uniformly and without residue on the workpiece surface, meaning that sharp abrasive grain is exposed at all times
Due to the special mounting system, the face of the unmounted flap wheels can be used to work very close to edges and in corners

Safety notes

As a rule, unmounted flap wheels should be used with the appropriate clamping flanges
The maximum permitted peripheral speed is determined as follows:
Unmounted flap wheels = 50 m/s
Unmounted flap wheels for angle grinders = 80 m/s
For safety reasons, it is imperative to remain within the stated maximum permitted rotational speed at all times
