Precision Grinding wheels

Centreless grinding is an OD grinding operation where the work piece seeks its own axis of rotation between the grinding wheel and a regulating wheel. The key components in the process are the grinding wheel, the work rest blade (used to support the work) and the regulating or “feed” wheel (the drive mechanism for the work piece). Centreless wheels are used in he manufacture of flexible or small revolving parts.

Norton offers a range of wheels for the production, maintenance and repair of cutting tools and machinery parts used in all types of manufacturing operations. Wheels of all sizes and shapes including conventional, diamond or CBN grinding wheels are used in tool and cutter manufacturing and maintenance.

Grinding wheels are used to generate the desired profile of gear teeth after heat treatment. The machine and gear type determine the shape of the grinding wheel. Continuous gear generation, profile grinding, bevel gear grinding, and power honing are the most common grinding processes in gear manufacture.

Roll grinding is found mostly in steel and paper mills where precision is paramount to reshape and polish rolls. Most roll grinding wheels are large in diameter (700-1080mm) and thickness (50-150mm). Depending on the surface finish required, Norton can provide roll grinding wheels with specific dimensions and specifications for your application requirement. Depending on the stage of the laminating process, a specific type of surface finish and roll shape is required.

The term surface grinding is used to describe the grinding of flat or profiled surfaces in which the wheel moves past the work piece in a flat plane, or vice versa. Surface grinding applications range from heavy stock removal, to precision grinding of contours. Associated applications are creepfeed and disc grinding. For these applications Norton offers a large range of wheels (diamond and conventional) as well as segments and cylinders.

Double disc grinding is used to reach tight parallels and surface finishes in the production of bearings and automotive components. Face grinding of inner and outer bearing rings, faces of cylindrical rollers and connecting rods are rectified after hardening using a double disc grinder.

Cylindrical grinding includes all outside grinding of round work, even when the finished product is not always a true cylinder. Requirements in cylindrical grinding vary from fast stock removal to ultra smooth (mirror) finishes. Cylindrical wheels are used extensively in the automotive, aerospace, shipbuilding, engine manufacture, turbine manufacture and bearing industries, as well as general shops and tool rooms. Depending on the type of application, different types of wheels can be used (conventional, CBN or diamond wheels), Norton can offer a complete solution.

Internal grinding refers to the grinding of bores, holes rings and tubes and is one of the most complex applications in the production of bearings, pipes and industrial components. Norton offers solutions for all operations from very rapid stock removal to more controlled processes capable of generating sizes and concentricity measured in microns. Conventional, CBN or diamond wheels are available for all ID grinding applications.

Flute grinding is a time-consuming and cost-intensive manufacturing step in drill and end mill production. In recent years, machines have become more compact, spindle power has increased, axis paths have been reduced and machine controls have become more efficient. At the same time, Norton has developed flute grinding wheels which meet these increasing requirements and which now enable the improved machine capacity to deliver a higher and more economic output.

Diamond and CBN grinding wheels are ideal for fluting, gashing and grinding clearance angles in the production and re-sharpening tungsten carbide and HSS tools.

The tungsten carbide tipped grinding wheels for circular blades have been designed for flank, face and top grinding.

Norton offers a diverse range of grinding wheels for all face and top grinding applications in the production of milling cutters.

Wheels are designed for the wet grinding of circular knives with tungsten carbide-steel combinations on Göckel and Reform machines and on Weinig machines for grinding profile knives for the wood industry.
