LIQUID HONING METHOD AND SLURRY FEEDER

PURPOSE:To increase the amount of stock removal as well as to make the surface finishing ever so smooth, by injecting a compressed fluid into slurry in its flowing down direction, while expanding this fluid at the upstream side leading a liquid jet stream to a workpart to be ground and then flowing together. CONSTITUTION:Slurry S being properly regulated by a flow control valve 27 flows down through a slurry pipe 20 and, when passing through a T pipe joint 21, is also regulated by a flow control valve 28, then injected with compressed air R discharged out of the tip of a fluid pipe 25 in a downstream direction and mixed with the compressed air inside the slurry pipe 20 while is given speedier acceleration than the gravitational acceleration by receiving pressurization of the compressed air. The mixed and accelerated slurry secures a wide area where a projecting area on a liquid jet stream becomes the product of integrated width W and specified thickness (t) of the jet stream. Since the compressed air is instantaneously expanded in volume, the spouted slurry is scattered after turning to numerous waterdrops and flows together with a liquid jet stream 16, thus increasing the amount of stock removal.
