摘要:
A grinding system for grinding feedstock includes a transport apparatus, a grinding apparatus, and a controller. The transport apparatus continuously transports feedstock of an arbitrarily long length at a desired feed rate, and the grinding apparatus grinds the feedstock transported by the transport apparatus. The controller controls a grinding position of the grinding apparatus and a longitudinal position of the feedstock during grinding to be coordinated with each other.

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 a metal binder. The contact-discharge truing/dressing method brings a rotated conductive grindstone into contact with a pair of electrodes to which a DC voltage or pulse voltage is applied, and subjecting the conductive grindstone to an intermittent truing/dressing by contact discharge produced when opening/closing a circuit of a positive electrode, electrode chips, a grindstone binder, electrode chips, a negative electrode, and parts of the side surfaces of dual-ring rotary electrodes insulated by an insulation layer being used as a pair of electrodes.

In a method for grinding a traction surface of a half-toroidal CVT disk, there is provided a grinding machine including a hold mechanism holding the half-toroidal CVT disk having a given machining allowance, and a machining mechanism including a tool for grinding the half-toroidal CVT disk. The grinding of said grinding machine is performed in a state that one of the half-toroidal CVT disk and said tool is inclined at a predetermined angle with respect to the other. A cutting angle, which is an angle to be formed by the cutting direction of said tool with respect to the axis of the half-toroidal CVT disk, is set to be in the range of ±15° with respect to the angle that a first cutting magnification at the time of that said tool contacts with an outer periphery position of the traction surface is substantially equal to a second cutting magnification at the time that said tool contacts with an inner periphery position of the traction surface, each of said first and second cutting magnifications being a ratio of an apparent machining allowance to the given machining allowance.

An apparatus for grinding edges of rigid materials including a support member, an upper grinding element rotatably mounted relative to the support member, a bearing affixed to the upper grinding element, a lower grinding element rotatably mounted relative to the support member, and an insert element removably affixed around the bearing and interposed between the support member and one of the upper and lower grinding elements. The insert element is of an annular configuration and has an outer diameter less than an outermost diameter of the grinding elements. The insert element is interchangeable with various other insert elements.

A reference straight-edge is mounted on the worktable of a machine tool so that the position of the worktable and a workpiece carried thereon can be determined in respect of the x-axis of the machine tool by sensing the straight-edge; in addition a linear scale is carried by the tool carriage of the machine tool for cooperation with a reading head to provide an indication of the tool position along the x-axis. Another linear scale is carried by the worktable and coacts with a read head to provide the position of the worktable and workpiece along the z-axis. The linear scale of the tool and the reference straight-edge, and the reading head and sensing device associated therewith are all in the same plane. The workhead and tailstock spindles are equipped with hydrostatic bearings which have sensing devices to determine forces applied to workpieces carried between the headstock and tailstock on a worksteady and cooperate therewith to activate a probe to offset such forces.
