The disclosed device comprises a manually-actuated micro positioning stage that incorporates a mechanism for measurement and electronic output of the stage slider position. A Hall Effect sensor device is used to sense rotary position of the lead screw. based on the lead screw pitch. Processor means converts the Hall Effect sensor measurement of the lead screw rotational displacement into linear displacement of the stage slider for presentation on an electronic display. A magnetically-permeable cap contains a small disc magnet that is poled diametrically and is affixed to the end of the lead screw that is in contact with the stage slider by means of a sensor housing. The Hall Effect sensor contained in a surface mount electronic package is enclosed in a sensor housing that is part of the stage slider that is in contact with the lead screw and is positioned coaxially with the lead screw.

Systems, methods, and apparatus for positioning and/or processing items, such as workpieces. The systems, methods, and apparatus may include or use a linear positioner forming a track. In some embodiments, the linear positioner may include a carriage configured to be driven along the track to a desired position, in response to a signal(s), such as a radiofrequency signal(s), received from a computer, which may be a general-purpose, handheld computer, such as a phone or tablet. In some embodiments, the linear positioner may comprise a shuttle including a motor and a carriage, and may be configured to drive itself as a unit along the track. In some embodiments, the track may include a rack having a linear array of teeth formed by two or more frame sections, such as table sections, coupled end to end, with each support section providing a segment of the rack.

A frame assembly module for a CNC machine support structure, the module comprising a frame assembly module support structure, and a traversing element, coupled to the frame assembly module support structure, for traversing the frame assembly module support structure, the traversing element comprising a frame assembly fastening feature for attachment of a second frame assembly module to the traversing element, and a spindle fastening feature of attachment of a spindle to the traversing element, the frame assembly module support structure comprising a traversing element fastening feature for attachment of the frame assembly module support structure to a different traversing block. The module may comprise steel tubing.

In the internal milling machine according to the invention for milling a work piece that rotates during machining with an annular internal milling cutter (5) on the one hand side the Z slide (4a, b) of each tool support (3a, b) includes a pass through opening and on the other hand side the transversal slide (7) supporting the internal milling cutter (5) is move able in the X-direction, the running direction of the mounting surface (1a) of the bed (1) wherein the mounting surface slopes downward in a forward direction. Based on this general configuration and in particular the arrangement of the Z-slides (6a, b) for the at least one tool support (3a, b) outside of the Z-supports (16a, b) for the opposite spindle stock (2) yields advantageous centers of gravity in particular of the move able components and a high level of stability of the machine and therefore high level of machining precision of the machine.

A flexure stage with modularized flexure units for convenient manufacturing, assembly and repair is provided. The flexure stage comprises a base, a first carrier, a plurality of first flexure units, a gantry unit, a second carrier, and a plurality of second flexure units. The first carrier is separated from the base and reciprocated along a first axis. The first flexure units are disposed between the base and the first carrier wherein each of the first flexure units comprises flexibility in the first axis. The gantry unit is located on the base and separated from the first carrier. The second carrier is set on the gantry unit and reciprocated along a second axis. The second flexure units are disposed between the first carrier and the second carrier wherein each of the second flexure units comprises flexibility in the second axis.

A variable spacing device includes a support member, a driving member, a number of movable graspers, a limiting block, and a pushing block. The movable graspers are slidably mounted in a line on the support member. Each movable grasper grasps a workpiece. The limiting block is mounted on the support member and arranged in parallel with the pushing member. The limiting block defines first sliding grooves having a length gradually decreasing along a same direction. The pushing block defines second sliding grooves having a length gradually increasing along a same direction. Each movable grasper moves within a corresponding one of the first sliding grooves and a corresponding one of the second sliding grooves. Two sidewalls of each first sliding groove and two sidewalls of each second sliding groove resist movement of the corresponding movable grasper.

The present disclosure provides a system and method relating to work tables. The system comprises a table that attaches to a drill press. Specifically, the present disclosure relates to a drill press table with a fence and optionally a drawer, a vacuum assembly, flip stop assemblies, and various other components. Various operation of using the table are described herein.

A positioning system moves an object in two generally orthogonal directions using a rotationally adjustable bearing system that connects the object to two pairs of non-parallel rails, the bearing system permitting the object to be smoothly translated in one or two directions to a desired position in planar space. This translation is performed smoothly notwithstanding a lack of parallelism between the linear rails.
