In this paper, coated micro-grinding tools with high wear resistance are successfully manufactured by vacuum multi-arc ion plating method, aiming at improving the grinding performance and prolonging the service life of micro-grinding tools. The principle of vacuum multi-arc ion plating is analyzed. Single factor coating experiment is conducted on the surface of specimens to investigate the effect of different preparation parameters on coating properties. It demonstrated during the present research that the interfacial reaction between metal titanium coating and diamond abrasive particles produces metallurgical bond. Meanwhile, the interpenetration between titanium coating and cobalt and nickel binder layer improves the binding force of the coating, which can firmly wrap diamond particles and slow down the shedding of diamond abrasive particles. When the arc current is 100 A, the voltage of the electromagnetic coil is 20 V and the deposition time is 2.5 h, coating properties with high wear resistance can be obtained.
