The present disclosure includes one or more resilient members for use in an apparatus used to form lapping plates. The resilient members can permit processing members such as charging elements and shaving blades to conform to irregularities in surface topography of lapping plate platens.

A method of processing a ferrule end face using at least one grinding wheel rotatable about a central axis and having a working surface with an abrasive element is provided. The method includes holding the ferrule stationary, engaging the end face of the ferrule and the working surface of the at least one grinding wheel, rotating the at least one grinding wheel about the central axis, and moving the at least one grinding wheel relative to the ferrule along a curve perpendicular to the central axis. Processing the ferrule in this manner imparts a convex shape of the end face of the ferrule. An apparatus for carrying out the method is also disclosed.

A manufacturing method of a carrier for a double-side polishing apparatus, including: preparing a carrier base material and insert thicker than the carrier base material, inserting the insert into a holding hole so as to protrude the insert from both sides of the front surface and back surface of the carrier base material, measuring each of a front protruding amount of the insert protruded from front surface of the carrier base material and a back protruding amount of the insert protruded from back surface of the carrier base material, setting each rotational speed of the upper turn table and lower turn table in starting-up polishing of the carrier so as to decrease the difference between the front protruding amount and back protruding amount, and a starting-up polishing step to subject the carrier to starting-up polishing at each set rotational speed of the upper turn table and the lower turn table.

Wheel back cavity groove processing equipment is disclosed in the present application, which includes a lower lifting system, a central brush system, groove brush systems, a synchronous clamping and rotating system, a left brush system, a right brush system, an upper lifting system and the like. The wheel back cavity groove processing equipment not only may be used for removing burrs from wheel back cavity grooves, but also may be used for removing burrs from bolt holes, a center hole, spoke edges and transverse corners, and simultaneously has the characteristics of high automation degree, high removal efficiency, advanced process, strong generality, and high safety and stability.

A cutting apparatus includes: a processing feeding unit that performs processing feeding of a chuck table adapted to hold a workpiece; and two cutting units in which rotational axes of two spindles coincide with each other and cutting blades mounted to the spindles face each other. Each cutting unit includes a flange mechanism in which the cutting blade having a cutting edge fixed to an outer peripheral edge of a one-side outer surface of a circular disk-shaped base is fixed to the spindle. The flange mechanism is fixed to a tip of the spindle, sucks an other-side outer surface of the base of the cutting blade, and fixes the cutting blade to the spindle with the one-side outer surface of the base exposed to the side of the tip of the spindle, and the one-side outer surfaces of the cutting blades fixed to the two cutting units.

A method for treating an interior weld joint located along an inner surface of a pipe includes the steps of: (a) advancing an internal grinder device within the pipe to the interior weld joint, wherein the internal grinder device includes a hollow housing that has a first open end and a first grinding implement that is disposed within the hollow housing and coupled thereto with a first biasing member; and (b) controllably rotating the hollow housing to at least a threshold speed at which time and under centrifugal force, the first grinding implement moves from an at rest retracted position to a deployed position in which the first grinding implement extends radially beyond the first open end for contacting and grinding the interior weld joint as the hollow housing and the first grinding implement are rotated.

The present invention is a probe forming device, the probe forming device comprises a spinning shaft, a first adjusting structure, a second adjusting structure, an electrolyte conveying member and a power supply. One of the holding member of the spinning shaft holds a workpiece, and a driving member drives the workpiece to move and abut the first adjusting structure and the second modulating structure. The electrolyte conveying member conveys an electrolyte to the workpiece, the first adjusting structure and the second adjusting structure, and is electrically connected. At least one positive end of the power supply is connected to the workpiece or the spinning shaft, and at least one negative end is connected to the first adjusting structure and the second modulating structure.

A method for manufacturing a rotor includes the following operations: the clamping of a workpiece in a grinding machine; the performance of one or more cylindrical grinding operations whereby a rotor shaft section is ground to the desired diameter with a cylindrical grinding disk; the performance of one more profile grinding operations whereby a rotor body is profiled with a profile grinding disk. During the manufacture of the rotor in the grinding machine, the workpiece is not undamped and the cylindrical grinding operations and the profile grinding operations are done with the same grinding machine.

The present disclosure includes one or more resilient members for use in an apparatus used to form lapping plates. The resilient members can permit processing members such as charging elements and shaving blades to conform to irregularities in surface topography of lapping plate platens.

The invention relates to a steel wire descaling device. The device includes one or more first steel wire descalers and one or more second steel wire descalers. A descaling roller for removing an oxide scale from a surface of a steel wire is disposed on each of the first steel wire descaler and the second steel wire descaler. The descaling roller of the first steel wire descaler is disposed inclinedly, the descaling roller of the second steel wire descaler is disposed horizontally. By inclinedly brushing the steel wire by using the first steel wire descaler and flatly brushing the steel wire by using the second steel wire descaler, the combination of flat brushing and inclined brushing allows oxide scales to be from steel wires without a blind spot.
