CS570 Fiber Disc

CS 570 fibre discs – grinding wheels for large-volume removal of stainless steel, steel, non-ferrous metals and aluminium
Grinding metals is a particular challenge for abrasive materials. Metals are among the most durable materials with high hardness. Stainless steel and high-alloy steels in particular place the highest demands here. CS 570 fibre discs are the answer to these requirements with their hard, very durable zirconium electrocorundum grain and very durable synthetic resin on a fibre substrate. The CS 570 fibre disc has special properties for processing stainless steel and aluminium:

reduced grinding temperature thanks to multi-bond
full filler
zirconia alumina grain
self-sharpening effect of the zirconia alumina grain
The zirconia alumina used in the CS 570 fibre discs from Klingspor is a synthetically produced, hard and very durable abrasive grain with a crystalline structure. The sharp edges of natural abrasives made of quartz, emery and garnet round off after a certain period of grinding, which reduces the grinding efficiency. Synthetically produced zirconia alumina reacts differently. Pieces of the crystalline structure break off, leaving new sharp edges. This creates an even grinding appearance with stable performance and long service life.

Prevents overheating
The fibre discs can be used at high temperatures. Thanks to the reduced grinding temperature (multi bond), even grinding with high pressure and high speed will not lead to overheating and discolouration of the ground metal workpiece so quickly. For safety reasons, the maximum operating speed of the fibre disc on the support disc is 80 metres per second. This speed is not exceeded provided that the following permissible values ​​are maintained:

115 mm diameter discs: 13,300 rpm
125 mm diameter discs: 12,200 rpm
180 mm diameter discs: 8,500 rpm
Using CS 570 fibre discs
The following support discs are available for CS 570 fibre discs: ST 358 A ribbed hard and ST 358 smooth medium hard. The support disc should be selected depending on the intended use. The medium-hard backing pad can be used to achieve an even grinding appearance because it adapts to the contour of the workpiece being ground. This backing pad is ideal for finer grinding, surface grinding and contour grinding. The hard backing pad is designed for rough grinding with a high stock removal rate. It is particularly suitable for deburring and aggressive rough grinding.
