1.EXPERIMENTAL STUDY ON CHIP FORMATION MECHANISM DUE TO SHOCK OF ULTRA-HIGH SPEED GRINDING
5.Companies to implement quality win market to brand development approach for users provide lubrication, sealing and damping, shock absorption, medium and high-low temperature, high speed, protective, long-life, green and difficulties package, and help users implement lubricants resin varieties optimization, and upgrading and domestically.
8.The vibration magnitude can be reduced by applying the shock vibration absorber in boring process ,The curves of the amplitude versus gap δ between the shock block and the hole in boring bar was gained by experiments with different cutting speed .The experiments show that the absorptive results is good when applies shock vibration absorber with suitable gap δ in boring process ,while the vibration may be strengthened with unsuitable gap δ.6figs.,2tabs.,3refs.
9.In order to investigate the chip formation mechanism of Q235A at ultra high speed, shock grinding experiment was done for steel Q235A at 720 m/s of ultra high speed, in which artifical diamond and CBN grains were used as abrasive material adhered to the head of bullet with 7.62 mm diameter and the 81 type rifle was used as accelerator.
10.The results of the rising displacement,strain and shock acceleration of the catenary at the typical position under the different speeds have been obtained in experiments. These results have improtant effects on analyzing the catenary vibration rule at quasi high speed condition and designing the structure of the high speed electric railway.
