In this paper the characteristics of the grinding temperature are experimentally investigatedin the vertical-spindle heavy surface grinding of mild steel. The main results are follows.
(1) In the grinding condition of sufficient self-sharpening, the area of heat source by thegrinding comes to the same apparent contact area between grinding segmental wheel andwork. The distribution of the heat source is considered uniform on the contact area.
(2) The grinding peak temperature on the contact area is comparatively low because themetal-removal rate par unit area of contact and the specific grinding force are small.
(3) The down slope of the temperature in the direction of the depth from the groundsurface is small because the contact length (direction of the work feed) between grindingwheel and work is long.
(4) The grinding peak temperature on the contact area has an up slope in the direction ofthe wheel running because of the increases of the flowing rate into work of heat.
(5) In case of the wide works, the temperature on the contact area becomes high.
