There are two methods companies use to flute these tools. methodtilizes straight faced wheels as this greatly reduces the amount of grinding wheel inventory used for many sized tools. however, this method tends to create high machine load and wheel wear. most of the work being done is at the leading edge of the wheel as depicted in figure 2.
Qflute prime grinding wheels feature an innovative high performance hybrid bond combined with optimised profile holding and free grinding behaviour. this makes flute grinding much more productive and cost effective while simultaneously delivering even better quality than what were already some exceptional previous grinding systems.
In comparison with similar high performance products on the market, qfluteevo grinding wheels reduce grinding force by up to 20, according to norton winter. they also achieve excellent edge stability. this prolongs service life and minimises downtime. the high grinding quality is reflected in the flutes outstanding surface finish.
Compared with the existing approaches, the present approach improves the flutegrinding accuracy and robustness withide range of applications for various flute sizes.
Currently, grinding after rough machining is the most effective method to obtain highprecision and highperformance face gears. however, the gear flank will inevitably be affected by the multisource errors e.g., cutter manufacturing errors, machine tool errors, cutter and workpiece installation errors, etc. in the machining process.
