Embodiments of the invention provide a device used for centering equipment having a center hole. The device includes a base; a central spindle partly coupled to the base; an upper supporting assembly partly coupled to the central spindle; and a centering device configured to act on the equipment having the center hole to perform centering operation. Using the centering device of the present disclosure to detect the deformation of equipment having a central hole, no fixtures are involved, thus saving the time for disassembling the equipment, and no need to select the fixtures to match the equipment, only to place the equipment in an appropriate way to complete the centering, thus improving the efficiency. In addition, no fixtures need preparing, which greatly reduces the costs.

A control system of a machine tool includes a hydraulic pressure adjuster. The hydraulic pressure adjuster includes a sequence program controller that includes components for adding a function of adjusting a hydrostatic pressure of a static pressure oil supplied to a hydrostatic pressure guide mechanism, which are a pressure setting unit, a constant acceleration motion controller, a workpiece-weight calculator and a supply state adjuster.

Presented is a method and apparatus for holding. The apparatus includes a base, the base operable to be fixedly attached to an opposing surface, and a head support coupled to the base, the head support being spaced from the opposing surface defining a grinder head gap, the head support having an end portion that is curved with an open top. The apparatus further includes a handle support, the handle support coupled to the base extending away from the opposing surface, the handle support having a curved portion and an open portion.

Disclosed herein is a workpiece unit containing a workpiece body, and a holding member which is arranged at least at a part of an outer circumferential portion of the workpiece body and directly contacts with at least a part of the outer circumferential portion.

An apparatus, having: a panel (100) comprising a top surface (102), a bottom surface (104), and a side surface (106) spanning the top and bottom surfaces; plural upper retaining slots (110), each upper retaining slot recessed into the panel through the top surface, extending parallel to the top surface, and opening through the side surface in at least one location (112), wherein each upper retaining slot comprises a trapezoidal shape; and a dog hole (122) extending through the panel from the top surface to the bottom surface.

A portable adjustable conveyor for use with a power tool for cutting a work piece. The portable adjustable conveyor has a one piece frame formed from a base plate integrally connected to first and second guide plates. Each guide plate has first, second and third groups of vertically aligned alignment holes oriented on a diagonal configuration to each other and spaced centrally in each guide plate. A removable roller engages between pairs of vertically aligned alignment holes in a first, second or third group of offset holes. The portable conveyer enables the power tool to process a work piece and reposition the work piece in less than 90 seconds repeatedly using different pairs of longitudinally aligned alignment holes with the removable roller as well as reduce static in the work place and increase lumens to the workpieces, all simultaneously.

A tooling base that is an improvement over current designs in the form of simplified number of parts and easier manufacturing of parts is described. The tooling base uses alignment fixtures on threaded rods that are restricted in their movement within the tooling base by stops. The stops are located either on the threaded shafts or on the alignment fixtures. This allowed degree of movement enables simplified part design and manufacture while maintaining the precision and accuracy of registration of a tooling fixture with the tooling base.

A magnetic drive transmission method includes the steps of: disposing solid magnetic device and ring-shaped magnetic device at top and bottom surfaces of work platform, while keeping the solid magnetic device in axial alignment with the hollow inner diameter of the ring-shaped magnetic device the solid magnetic device enters within the magnetic field lines of the ring-shaped magnetic device so as to create a magnetic field downstream between the solid magnetic device and the ring-shaped magnetic device that changes the thrust of the same polarity repulsion and to further cause the solid magnetic device and the ring-shaped magnetic device to attract each other in a balanced manner, and then using the ring-shaped magnetic device to drive the solid magnetic device in moving a predetermined workpiece along one surface of the work platform to a predetermined location.
