The cut-off, grinding and abrasive flap wheels are characterised by high durability and short cutting times. Their design is tailor-made in terms of abrasive grain, bonding, structure, shape and composition. Added to this are state-of-the-art manufacturing technologies that create 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-guided 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 moulding compound, the bonding (usually fibre glass fabric) and a label with a bore ring. The moulding compound contains a wide variety of abrasive fillers to enhance the cutting properties. These grinding agents are extremely abrasive and ensure a high degree of wear and tear on our machines and equipment. For example, when hard silicon carbide is pressed into wafers for use in the stone industry, an extremely large amount of dust is produced, which further increases wear. And since work is carried out in three shifts, maintenance and repairs can only be carried out on a regular basis at fixed times. In terms of the ambient conditions, it could hardly be more abrasive. The bearings have to permanently withstand the various materials used in grinding wheel production.
The automatic pressing machines work under the harshest conditions; they guarantee consistent thickness and pressing of the products. The cutting and grinding wheels are then moved to the curing ovens. In order to guarantee consistently good quality here, they are first placed between steel plates, which must be removed again after the curing process. This, in turn, is done by tailor-made automatic separators, which are used for the necessary destacking.
