High-speed grinding with CBN grinding wheels — applications
CBN grinding wheels. Aluminium oxide. 1. Introduction. More than 25 years of high-speed grinding have expanded the field of application for grinding from classical finish machining to high-performance machining. High-speed grinding offers excellent potential for good component quality combined with high productivity.
The grinding allowance can be substantial, e.g. 0.4-1.2 mm, which necessitates the use of cBN grinding wheels. Grinding and abrasive fine finishing offer unique performance with respect to the achievable R a and R z, in addition to requirements for (i) level difference on the core surface (R k), and (ii) reduced peak and valley depth (R pk and
Diamond & cBN Products
If you're precision grinding and finishing steel or carbide you need a durable wheel that will withstand high grinding forces and perform well in offhand finishing applications. Norton vitrified bond grinding wheels will give you a precision finish and will meet your exact requirements when plunge grinding or offhand finishing.
In wet grinding, wheel speeds in the range of 5000 to 6500 SFPM (25 to 33 m/s) provide excellent results. In general, the higher speeds improve both wheel life and metal-removal rates. The traverse feed rate should be kept constant because of the cool, free-cutting characteristics of CBN grinding wheels.
Vitrified Bond CBN Grinding Wheels
Cubic boron nitride (CBN) is a highly durable synthetic abrasive mineral, second only to diamond in hardness. This durability makes it ideal for grinding hardened steel and superalloys – materials commonly used in the manufacturing of powertrain, bearing and turbine components.
Reducing the grit size of the grinding wheel is one way to improve the surface finish. This table shows which grit size to use in relation to the desired finish for CBN and diamond grinding wheels. Before making a change to the grit size, dressing the wheel using less aggressive parameters is advised.
CBN grinding wheel can improve the finishing level of
CBN grinding wheel is suitable for high-speed, ultra-high-speed grinding, and grinding sharp, small unit wear, grinding steel wear ratio can reach 4000-10000, equivalent to the ordinary high-speed grinding wheel 150-200 times, so the grinding efficiency is very high.
Highest quality diamond and cBN abrasives matched to superior high temperature bond systems, guarantee high performing wheels for all dry & wet grinding applications. Electroplated Wheels. Electroplated wheels are mainly used for applications like grinding of engine valves, transmission shaft, fuel injection components. Metal bond wheels.
