Hermes Abrasives Ltd.

Due to this technique's advantages, these days it is difficult to imagine industrial machining without external cylindrical grinding. The external cylindrical grinding process is used for precision-grinding and polishing of redationally symmetrical parts. Its chief area of application extends from the centreless external cylindrical grinding of stainless steel pipes in a continuous process to the external cylindrical grinding between centres of piston rods with subsequent superfinishing, and also covers the external cylindrical grinding of high-alloyed stainless steel wires. Especially for external cylindrical grinding Hermes abrasives are bringing benefits you'll appreciate:

Preparing surfaces for painting or polishing is one of the most demanding abrasive tasks in the automotive and furniture industries. The abrasive products required for this process have to adapt extremely well to the contours of the workpiece and be highly versatile – whilst their quality must be of the highest order. The FineNet FN 915 foam-laminated and velour-backed abrasives especially developed by Hermes not only easily meets these requirements, but are also highly

The new ceramic grain abrasive sleeves CERAMIT® CN 466 Z are very durable and achieve double stock removal rates compared with standard products. They are especially suitable for cleaning, light deburring, flat and profile grinding and finishing hard and tough materials like stainless steel, nickel or titanium alloys with low thermal conductivity. The spiral winding technique ensures construction stability and eliminates joint chatter marks. These products are available in grit sizes + 40, + 60 and + 80 and standard dimensions are available from central stock.

Design and brightness are the priority in surface finishing. Different stainless steel surfaces are required by stainless steel finishers depending on applications and requirements. A distinction is made here between ground, brushed and duplex (ground and brushed) finishes. The surface finish of cold and hot-rolled stainless steel sheets, coils and panels is usually applied in service centres, but in some cases directly at steelworks. The surface finish is usually created by dry grinding, but for certain applications, also using a coolant additive such as emulsion or oil. Wide belt and brush-grinding machines are used to achieve an ideal, even surface finish. These can be arranged both individually or as a combined unit (grindingbrushing) in one machine or as consecutive grinding stations with separate individual machines.

Hermes abrasives generate process cost benefits when finishing crankshaft bearing seats. To help its customers achieve those final values for concentricity, roughness depth and percentage contact area, Hermes supplies aluminum oxide grinding film FB 637, which is used in the form of cycled material on a roll and which has replaced conventional “stone honing“. The grinding material constantly being used new as a result of the cycling results in greater production effectiveness and simultaneously guarantees much greater process reliability.
