Diamond / CBN Tools General Information Diamond and CBN product range PFERD offers a high-quality, efficient and immediately available range of systems for surface finishing work – coarse to mirror polishing, right up to material cutting. In addition to this wide range of standard grinding tools, PFERD also specialises in the customer-specific manufacture of electroplated-, resinoid-, ceramic and metal-bonded diamond and CBN tools. Superhard abrasives These tools cut extremely well and have both a longer tool life as well as a better dimensional stability than standard grinding tools. Comparison:...

Diamond / CBN Tools General Information Advantages of grinding tools with diamond and CBN ■■Avoids thermal damage to the workpiece as low resulting grinding temperatures. ■■Consistent quality for various types of workpieces. Tool life Grinding ease Profile stability Aluminium oxide Aluminium oxide Aluminium oxide The information in the adjacent diagram is valid when the optimal conditions and the required parameters are maintained. Aluminium oxide Diamond and CBN tools are characterised by ■■longer tool life, ■■improved abrasive qualities and ■■longer-lasting profile-holding properties in comparison...

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 CBNtools...

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 involving...

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 to...

Diamond / CBN Tools Cutting Speeds and Safety Recommendations Conversion table Example: Diamond grinding point Diameter: 20 mm, Cutting speed: 25 m/s Rotational speed: 23.870 RPM from ➊ cutting speed [m/s] ➋ in rotational speed [RPM] ➌ per tool diameter Safety note PFERD diamond and CBN grinding tools comply with the highest quality and safety requirements and are manufactured and labelled according to the European safety standard EN 13236. PFERD manufactures all its tools in accordance with the specified safety regulations. The oparator is responsible for the grinding application; correct tool...

Diamond / CBN Grinding Tools, Electroplated Bond

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 comparatively...

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 tool...
