Diamond / CBN Tools Bond Types Electroplated bond Resinoid bond Ceramic bond Resinoid bond Ceramic bond Abrasive structure Abrasive structure Abrasive structure Electroplated diamond and CBN tools have a monolayer of abrasive coating on a metal substrate which is bonded through a nickel layer. This creates a very open tool surface with large chip spaces. The abrasive coating of a resinoid-bonded diamond or CBN grinding wheel is composed of ■■grit, ■■bond and ■■filling material. The bond is compacted so densely so that it contain no pores (see sketch). The grinding layer of ceramic-bond...

Diamond / CBN Tools Grit Size Comparison Grit size comparison: Micro-grit sizes acc. to ISO 6106 and acc. to US mesh size Grit sizes Definition of grit size Grit designation [µm] ISO 6106 (FEPA Standard) Equivalent US merk number/Inch US mesh size smaller Grit size larger Diamond and CBN grain weights are conventionally measured in carats (ct). Thus, a C 25 concentration means a carat weight of 1,1 ct per cm³ of coating volume. A high concentration of abrasive particles makes the tool more wear-resistant, which is particularly desirable for profile grinding operations or in applications...

Diamond / CBN Tools Cutting Speeds and Recommendations for Use Recommended cutting speeds The recommended cutting speed ranges are dependent on each application and always lie below the maximum cutting speed of the tool. The recommended RPM gives optimum cost/ benefit. The wide range of tasks and applications makes it very difficult to define generally applicable technical parameters for electroplatedbond tools. The rates given below should be considered as a guideline only. The recommended cutting speeds serve only as guideline values. PFERD offers individual advice on questions referring...

Diamond / CBN Grinding Tools, Electroplated Bond Special Tools Made to Customer Requirements PFERD manufacturing strengths Manufacturing tools to customer specifications is one of PFERD‘s particular strengths. Electroplated abrasive tools are fast-cutting products. Tool bodies of almost any geometry can be coated with diamond or CBN abrasive. As a result, this tool group is unsurpassed when it comes to manufacturing flexibility and sheer diversity of realizable tool shapes. Electroplated tools have high cutting action. Due to their monolayer abrasive coating, electroplated bond tools are...

Diamond / CBN Grinding Tools, Electroplated Bond Application Information and Recommended Applications The advantages of electroplated diamond and CBN tools ■■The abrasive grains project well out of the bond, leaving large chips spaces which prevent tool loading even at high removal rates. ■■Sharp, superhard abrasive particles ensure maximum cutting performance without undesirable heat build-up. ■■The tools are coated with a monolayer of abrasive grit. They are therefore cheaper than other diamond and CBN tools, which makes them suitable for processing smaller batch sizes. ■■Virtually any...
