Ideal for rough grinding applications – the Klingspor fibre discs CS 565
The fibre discs CS 565 by Klingspor allows for quick and effective work – especially during rough grinding applications. Distinguished by a high level of aggressiveness and an outstanding price/performance ratio, these discs are a particularly good choice for use on
- steel,
- metal and stainless steel and
- other types of metal.
The CS 565 is available with a variety of grits, hole types and different diameters.
Aggressive and self-sharpening: the abrasive grain made of zirconia alumina
The Klingspor fibre discs CS 565 come with an abrasive grain made of zirconia alumina. This grain is exceedingly tough and hard and possesses a uniform crystalline structure. As they are self-sharpening, the discs are sure to deliver perfect grinding results over a long period of time. All types of abrasive grains used by Klingspor are made synthetically. This manufacturing process ensures that the products retain their properties and deliver consistently excellent quality over the course of their service life. The close coating of the blue abrasive material ensures a high removal rate as it covers nearly the entire surface of the fibre discs CS 565 with abrasive grain. Better still, the high coating density also guarantees a long service life. The coating combined with the self-sharpening zirconia alumina grain lets the user process steel, metal and stainless steel with minimal material use and, thus, at extra low cost.
The top coat: solid synthetic resin with great adhesive force
Just like any other abrasive made under the Klingspor brand, the fibre discs CS 565 come equipped with a synthetic resin top coat. Its high adhesive force creates a tight bond between the backing and the abrasive grain. The top coat made of solid synthetic resin also supports the abrasive grain while being subjected to the lateral forces generated during grinding. Klingspor applies laser technology and product-accompanying weight measurements to verify the uniformity of the top coat. This level of dedication invested in the top coat is just another testimony to the exquisite quality of every single Klingspor product.
Fibre discs CS 570 – fibre discs that deliver a high removal rate on stainless steel, steel, NF metal and aluminium
Grinding work on metal presents a particularly daunting challenge to any abrasive. Metals prove to be difficult materials as they are tough, yet exceptionally hard at the same time. The most formidable of these metals are stainless steel and high-alloy steels, so-called super alloys. The fibre discs CS 570 tackle these challenges with an extra hard and ultra tough abrasive grain made of zirconia alumina that is bonded to a vulcanised fibre backing plate with a strong synthetic resin. The fibre disc CS 570 possesses characteristics that make it a particularly good choice for processing stainless steel and aluminium:
- Cool grinding thanks to multibond
- Close coating
- Grain made of zirconia alumina
The self-sharpening effect provided by the zirconia alumina grain
The zirconia alumina used for the fibre discs CS 570 by Klingspor is a synthetically made grain with a crystalline structure that is exceptionally hard and tough. The sharp edges of natural abrasives made of quartz, emery or garnet wear out over time, resulting in reduced abrasive performance. Synthetically made zirconia alumina acts differently. Wear causes individual portions to break out of the crystalline structure, leaving behind new, sharp edges. This will result in a uniform scratch pattern at a continuous removal rate and a long service life.
Prevention of overheating
Fibre discs are perfect for use in high temperatures. The cool grinding ensured by the green multibond prevents premature overheating and discolouration of the metal on the workpiece, allowing for smooth operation even at a high contact pressure and high speeds. For safety reasons, the maximum operating speed of a fibre disc when fitted to a backing pad must not exceed 80 metres per second. The following permissible values are designed to keep the speed within this limit:
- For discs with a diameter of 115 mm: 13,300 revolutions per minute
- For discs with a diameter of 125 mm: 12,200 revolutions per minute
- For discs with a diameter of 180 mm: 8,500 revolutions per minute
For use with the fibre discs CS 570
Available for the fibre discs CS 570 are matching backing pads, ST 358 A ribbed hard and ST 358 smooth medium. The backing pad must be selected according to the intended application. The medium backing pad is suited for applications requiring a uniform finish as it conforms perfectly to the contours of the workpiece. Its properties make this backing pad ideal for finer grinding work, surface grinding or grinding contours. The hard backing pad is used for rough grinding at high removal rates. It performs especially well when used for deburring and aggressive grinding.
