CS 570 Fibre Discs
Description
Abrasive discs for high stock removal rates on stainless steel, steel, non-ferrous metals, and aluminium.
Metal grinding presents a unique challenge for abrasive products. Metals belong to the class of tough materials, in addition to having high hardness. Above all, stainless steel and high-alloy steels, so-called superalloys, pose the highest demands. The CS 570 vulcanized fibre discs meet this challenge with a hard, highly tough zirconia alumina abrasive grain, bound with a strong synthetic resin bond on a vulcanized fibre backing.
For machining stainless steel and aluminium, the CS 570 fibre disc offers special features:
- Cool grinding thanks to the multi-bond (multibond)
- Close coating
- Zirconia alumina grain
Highlights
The zirconia alumina abrasive grain used in Klingspor's CS 570 vulcanized fibre discs is a synthetically manufactured, hard, and highly tough abrasive grain with a crystalline structure. The sharp edges of natural abrasives like quartz, emery, or garnet become rounded after some time, which reduces the sanding performance. Synthetic zirconia alumina reacts differently: as individual parts of the crystalline structure break off, new sharp edges are exposed. This ensures a homogeneous finish, continuous stock removal, and a long service life.
Vulcanized fibre discs can be used at high temperatures. Thanks to cool grinding (multibond), overheating and discoloration of the workpiece metal are prevented, even when working with high application pressure and high rotational speeds. For safety reasons, the maximum operating speed of a fibre disc on a backing pad must not exceed 80 metres per second.
The following permissible values help ensure this speed is not exceeded:
- For discs with a diameter of 115 mm: 13,300 rpm (revolutions per minute)
- For discs with a diameter of 125 mm: 12,200 rpm
- For discs with a diameter of 180 mm: 8,500 rpm
Using the CS 570 fibre discs
Compatible backing pads are available for the CS 570 vulcanized fibre discs: the ST 358 A ribbed, hard model, and the ST 358 smooth, medium-hard model. The backing pad must be selected based on the application. The medium-hard backing pad is suitable for achieving a homogeneous finish, as it adapts to the contours of the workpiece. This backing pad is ideal for finer sanding tasks, as well as for surface or contour grinding. For coarse sanding work with high stock removal rates, the hard backing pad is used. This pad is particularly well-suited for deburring work and aggressive grinding.
