The cut-off, roughing and flap discs are characterised by high trade show resistance and short cutting times. Their design is customised in terms of grain, bond, structure, shape and composition. In addition, they are manufactured using the latest trade show state of the art technology, enabling a comprehensive range of products. As a member of the Association of Abrasive Manufacturers and the oSa, the organisation for the safety of abrasive tools, the specialist makes an active contribution to user safety. After all, the processing speeds of hand-held discs, for example, are 80 or up to 100 m/s, which can lead to enormous thermal and mechanical loads on the tools. Grinding wheels essentially consist of a reinforcing material, a pressing compound, the bond (usually glass fibre fabric) and a label with a bore ring. The moulding compound contains a wide variety of abrasive fillers to improve the release properties. These abrasives are extremely abrasive and cause a high level of wear on our machines and systems. If, for example, hard silicon carbide is pressed into discs for use in the stone industry, an extremely large amount of dust is produced, which further increases wear. And because we work in three shifts, maintenance and repairs can only be carried out at regular intervals. In terms of environmental conditions, it could hardly be more abrasive. The bearing must be able to withstand the various materials used in grinding wheel production over the long term.
The automatic presses work under the harshest conditions; they guarantee consistent thickness and compaction of the products. The cutting and grinding discs are then sent to the hardening ovens. In order to guarantee consistently good quality, they are placed between steel plates beforehand, which have to be removed again after the hardening process. This is done using customised automatic separators, which are used for the necessary destacking.
