IMS-H grit of 35/40 mesh made by Tohmei Diamond Co. was prepared by electrodeposition on the truncated cone face on the top of a pencil-like holder at current densities of 3, 5 and 7A/dm2. Disk specimens made of hard metal were revolved, the grit was fed to the specimen surface, and the surface was ground in a spiral configuration to avoid repeated grinding of the same place.It was found that: 1) The grinding depth is changed both by the small smash of the grit edge and by the elastic deformation of the electrodeposited layer. 2) The current density had a great influence on the total amount of grinding and the grinding velocity, but did not affect the experimental results. 3) Grit retention was influenced by the grinding depth and the current density of electrodeposition.
