Abrasive Spiral Bands General Information Recommendations for use
PFERD offers different types in terms of shapes, dimensions, abrasives, grit sizes and packaging units. Abrasive spiral bands are designated “Cylindrical Abrasive Sleeves” according to ISO 2421.
■■The abrasive spiral bands can be mounted and removed by turning them slightly to the right and pulling at the same time. ■■Abrasive spiral bands can be changed more easily, if the rubber drum holder is clamped into the tool drive. ■■The abrasive spiral bands can only be guaranteed to fit securely if minimum speed is maintained. ■■Abrasive spiral bands perform best at a cutting speed of 20-30 m/s. ■■By using the appropriate grinding oil for the different materials, the tool life and the abrasive performance of the abrasive spiral bands can be substantially increased. For detailed information and order data on grinding oils, please refer to page 110.
PFERD offers matching cylindrical and conical rubber drum holders. Rubber drum holders are re-usable holders for abrasive spiral bands and are designated as “Holding Fixtures for Cylindrical Abrasive Spiral Bands” according to ISO 15637-1. A closely toleranced fit ensures that the sleeve will remain firmly secured to the drum holder during grinding.
Advantages
Safety recommendations
■■PFERD has an extentive range of abrasive spiral bands of various grit types and holders suitable for a wide range of applications. ■■Drum holders are fully reusable. ■■Slots allow the drum to expand during grinding, thereby tensioning the abrasive sleeve. ■■A special manufacturing method ensures an outstanding tool life, even in heavy-duty use. ■■Particularly high stock removal and very aggressive abrasive action.
Safety notes ■■The maximum permissible peripheral speed is 30 m/s. ■■For safety reasons, it is imperative to remain within the stated RPM limit. ■■Do not let the abrasive spiral bands project over the rubber holder. ■■Observe the VDS (Verband deutscher Schleifmittelwerke: Association of German Abrasive Manufacturers) safety guidelines “Safety guidelines for the correct use of abrasive belts”. You can find this information on our homepage, www.pferd.com.

Cutting speed abrasive spiral bands In this diagram, the cutting speeds are represented using blue diagonal lines. The vertical line representing the tool dia. meets the given cutting speed (diagonals). From its point of intersection proceed horizontally to the left margin where you will find the corresponding rotational speed [RPM] of the abrasive spiral bands and the machine. Example: KSB 4530 A 60 Cutting speed: 20-30 m/s Speed range: 8.500-12.500 RPM
