Abstract: In a rough grinding step the large quantity of coolant supplied to cool the grinding point enables the flow to pass through a wheel-following air layer and reach the grinding point while the supply of an air jet is stopped during this step. At a fine grinding step, the grinding point can be cooled with a small quantity of coolant in so far it is reliably supplied to the grinding point. This is realized by supplying an air jet to intercept the wheel-following air layer which rotates to follow the grinding wheel, while supplying the coolant in small quantity. Consequently, the coolant is prevented from being scattered by the air jet and suspended in form of mist when supplied in large quantity at the rough grinding step, and the coolant quantity used can be reduced at fine grinding step and minute grinding step.

Abstract: The present invention supplies coolant to a grinding wheel surface and reliably guides the coolant to a grinding point on the grinding wheel surface, thereby significantly reducing the amount of coolant to be used.In a grinding method and device for supplying coolant while grinding a workpiece W with a rotating grinding wheel 1, a fluid nozzle 2 is disposed upstream from a grinding point 11 on the circumferential surface 10 of the grinding wheel 1. The fluid nozzle 2 blows a jet of fluid across an air layer 12, which is a layer of flowing air dragged along the circumferential surface 10 of the grinding wheel 1, from one lateral side of the air layer 12 to the other lateral side thereof. A grinding fluid nozzle 3 supplies coolant to a region between the grinding point 11 and a cutoff position 13 at which the fluid jet from the fluid nozzle 2 has deflected the air flow from the air layer 12. The coolant supplied from the grinding fluid nozzle 3 contacts the grinding point 11 on the grinding surface 10.

Abstract: A method and apparatus for grinding a cylindrical surface of a workpiece by a traverse movement of a grinding wheel having a relatively narrow grinding surface. To improve the cylindricity of cylindrical surface, the traverse grinding is divided into a rough traverse grinding and a finish traverse grinding. In the rough traverse grinding, a traverse girding is carried out with a large depth of cut which would causes a deterioration of the cylindricity at one end of the cylindrical surface. In the finish traverse grinding, a traverse girding is carried out with a small depth of cut to improve the cylindricity. In another embodiment, one of grinding conditions such as the traverse speed of the grinding wheel, the rotational speed of the workpiece and the peripheral speed of the grinding wheel is changed when the grinding wheel approaches an end of the cylindrical surface at which the traverse grinding ends so as to make the grinding force constant, thereby improving the cylindricity of the cylindrical surface. In other embodiments, the position of the wheel head is compensated based upon the measured diameter of the cylindrical surface so that the entire area of the cylindrical surface has a desired diameter. This compensation also improves the cylindricity of the cylindrical surface.

Abstract: A cooling apparatus includes a lubricating fluid tank, a lubricating fluid nozzle, a lubricating fluid regulating device, a cooling fluid tank, a cooling fluid nozzle and a cooling fluid regulating device. The cooling fluid nozzle supplies cooling fluid to the workpiece to enhance cooling effect of the cooling fluid. The lubricating fluid nozzle feeds lubricating fluid to the machining zone to prevent frictional heat generated in the machining zone from raising temperature of the workpiece. Since an appropriate amount of the lubricating fluid within the range helps the cooling effect of the cooling fluid, a quantity of the cooling fluid is reduced within the minimum range of the cooling fluid. A consumption of the lubricating fluid is much smaller than that of the cooling fluid. Therefore, a total amount of the fluids is extremely reduced. The range of flow rates of the lubricating fluid has an upper limit that is preferably approximately 100.0 cm3/h or smaller in 1.0 mm of a contacting length in the machining zone. The range of flow rates of the cooling fluid has an upper limit that is preferably approximately 500.0 cm3/min or smaller in 1.0 mm of a contacting length in the machining zone.
