A tool has a machine body, a driving assembly, and a machining assembly. The driving assembly has a first holding base, a second holding base, a threaded rod, a moving base, and a thermal compensation gap. The threaded rod is formed as a single part and has a driving thread segment, a first assembling segment, and a second assembling segment. The driving thread segment has a first end and a second end opposite the first end. The thermal compensation gap is formed between the first end of the driving thread segment and the first holding base. The machining assembly is mounted securely on the moving base.

A technique facilitates operation of a split lead nut system which may be used in combination with a lead screw. The split lead nut system may be constructed with a split lead nut having a plurality of lead nut sections, e.g. two lead nut sections. The lead nut sections may be selectively released, via a clasp mechanism, to enable separation of the lead nut sections. When the lead nut sections are separated, the split lead nut disengages from the lead screw such that the split lead nut and the corresponding lead screw may be rapidly shifted with respect to each other. This allows a tool coupled with the lead nut to be rapidly repositioned. Once at a desired position, the lead nut sections may be closed and reconnected with the corresponding lead screw to enable the desired, controlled movements of the tool via rotation of the lead screw.

Machining tool comprising a frame in which a drive shaft for a tool is mounted so as to pivot about a rotation axis and to move axially along the rotation axis. The shaft is connected to two rotary motors, namely a first motor connected to a member for meshing with a fluted portion of the shaft in order to drive the shaft in rotation and a second motor connected to a nut engaged with a threaded portion of the shaft in order to move the shaft axially. The motors are connected to at least one control unit designed to control the motors independently of one another, and the first motor and the second motor are coaxial with one another.

A sliding table includes a sliding seat having a seat body made from a first material and disposed between two main rigid rails parallel with each other. The seat body has two opposite rail recesses opening toward the main rigid rails, and two inner cyclic track holes disposed between the rail recesses. Two seat body rigid rails made from a second material harder than the first material are fixed in the rail recesses to confront the main rigid rails. Two roller belt modules are arranged in two cyclic track members overmolded to the seat body. When the seat body moves along the main rigid rails, each roller belt module circulates along one of the cyclic track members.

A manipulator system having a positioner having a primary rail, a first coupling linkage, and a second coupling linkage. The first coupling linkage couples the primary rail to a base and positions the primary rail along a first plane. The system has another positioner having a secondary rail, a third coupling linkage, and a fourth coupling linkage. The third coupling linkage couples the secondary rail to the base and positions the secondary rail along a second plane which is parallel to the first plane. A common link couples to the primary and secondary rails via linkages. Each of the second and fourth coupling linkages includes a joint for linear motion along the respective rail, and a revolute joint for relative pivoting between the respective rail and the common link. A position and orientation of the common link are adjustable by the joints and revolute joints.

A machine tool for machining workpieces has a machine frame, at least one component part which can be moved along a movement path by means of a power-operated drive unit, at least one frame part, which is connected to the machine frame and which is arranged at an end position in the movement path of the component part, and at least a first stop, via which the component part in contact with the frame part when said component part is in the end position, wherein the first stop lies outside the movement path.

The invention is a modular table-top automation apparatus, or for short, a tac, a word derived from an acronym for a table-top automation center, of which, this is the first. Employing integrated mechanical and electronic systems, a tac is a flexible, programmable apparatus, readily reconfigurable, which can be used as either a stand-alone unit, or as a cell within a configuration of other tacs or machines. The tac can utilize various purchasable application devices, mounted on one or two horizontal carriage rail assemblies, which extend past both sides of a frame containing a central work area, giving it a unique ability to load, position, perform numerous operations and unload a wide variety of small parts or assemblies. By combining with optional rotary magazines positioned on both sides of the frame, the tac can be set-up as a fully automatic “load and walk-away” production center.
