  • How to Reduce the Effect of Vibration in Production Grinding

    01/09/2018· The grinding test was performed at the SaintGobain Higgins Grinding Technology Center near Boston, Massachusetts The test machine was an Elb creepfeed/surface grinder The operation was slot grinding using an 8inchdiameter, ½inchwide conventional abrasive wheel The material ground was 4340 hardened steel The wheel was intentionally thrown out of balance by adding weights to one side of the wheel hub The vibrationThe effects of ultrasonic frequency on the grinding force and surface quality were analyzed from the grinding experiment on ZTA nanocomposite ceramics The results indicate that, in the same parameters, ultrasonic normal grinding force is about 65 to 85 percents of the ordinary grinding condition, and the surface quality is better than that of ordinary grinding condition, as the frequencyUltrasonic Vibration Grinding Test of Composite CeramicsA real grinding test is not suitable for obtaining a declared value, as the spread for this method is large Furthermore, in order to obtain enough data to handle the large spread, the time consumption is unreasonably high 1 Scope This Technical Report presents an evaluation of a roundrobin test of vibration measurement methods for determining vibration in handheld grinders The aim of theISO/TR 27609:2007(en), Vibration in handheld tools
