摘要： A contact-discharge truing/dressing method and a device therefor, capable of very simply conducting truing/dressing of a superabrasive grindstone, especially a superabrasive grindstone having metal binder. The contact-discharge truing/dressing method comprises the steps of bringing a rotated conductive grindstone (101) into contact with a pair of electrodes to which a dc voltage or pulse voltage is applied, and subjecting the conductive grindstone (101) to an intermittent truing/dressing by contact discharge produced when opening/closing a circuit consisting of a positive electrode, electrode chips, a grindstone binder, electrode chips, and a negative electrode, parts of the side surfaces of dual-ring rotary electrodes insulated by an insulation layer (203) being used as a pair of electrodes.

摘要： A combined cutting and grinding tool comprising columnar diamonds (22) arranged so as to protrude from the surface of the tool and conductive bonding member (24) for integrally bonding the columnar diamonds (22) to the surface of the tool, wherein the bonding member (24) performs electrolytic dressing while allowing a conductive fluid to flow between the same and electrodes (4) facing the same at intervals, whereby the columnar diamonds (22) can protrude. This arrangement makes it roughly work a ductile material with a large depth of cut, to precisely grind a brittle material with efficiency and stability and to offset variation in working position due to abrasion.

摘要： A rotating table 2 that holds a flat neutron lens component 1 and rotates about an axis of rotation Z , a circular-disk type of metal-bonded grinding wheel 3 with tapering surface 3a on the outer periphery thereof, a grinding wheel driving device 4 drives and rotates the grinding wheel around the axis A thereof, an electrode 5 with a surface close to the single tapering surface or the plurality of tapering surfaces of the grinding wheel, a power source 6 that applies an electrolytic voltage between the grinding wheel and the electrode, and a grinding fluid feeder 8 that supplies a conducting grinding fluid between the grinding wheel and the electrode are provided. The angle of the tapering surface 3a of the grinding wheel is formed to be more acute than the angle of a V-shaped groove to be formed on the surface of the neutron lens component, the axis of the grinding wheel is positioned at an oblique angle to the axis of rotation of the neutron lens component by the grinding wheel driving device 4, and the angle of obliqueness θ can be slightly varied at that location. Thus, fine ring-shaped protrusions can be formed accurately with an excellent surface finish and a low processing force, on the surface of a neutron lens component made of graphite etc.

摘要： There is here disclosed a metal-less bond grinding stone for protrusion of grains on the grinding stone by electrolytic dressing, comprising abrasive grains and a bond portion for holding the abrasive grains, wherein the bond portion comprises a carbon-containing nonmetallic material alone. Furthermore, this metal-less bond grinding stone is used, whereby a current which is allowed to flow between the grinding stone and the electrode is controlled within a desired range. In this way, environmental pollution with a waste liquid containing heavy metal ions and metal contamination of device wafers can be prevented, and a mirror-like high-quality level ground surface can be obtained with a satisfactory efficiency.
