A tapping apparatus adapted for tapping a workpiece includes a lower die unit to drive the workpiece to move along a conveying direction, and an upper die unit disposed above and movable upwardly and downwardly relative to the lower die unit. A tapping mechanism is disposed between the lower and upper die units to be driven by the upper die unit for tapping the workpiece so that the workpiece is formed with a tapped hole. A thread checking mechanism is disposed between the lower and upper die units and is spaced apart from the tapping mechanism along the conveying direction. The thread checking mechanism is driven by the upper die unit for checking the tapped hole of the workpiece.

A powered threading machine is described. The threading machine is compact and portable. The threading machine includes a tube frame having a rearward wheel assembly and an extendable handle at the front of the machine. A particular sump configuration is used to prevent loss of cutting oil during operation and transport of the machine.

A method for machining a plurality of surfaces of a respective plurality of drawers in an article of furniture includes mounting the article of furniture to a support structure to form a work piece, positioning the work piece on a base of a vertical gantry router in an orientation such that the plurality of surfaces are generally perpendicular to a cutting head of the vertical gantry router, and machining the plurality of surfaces with the vertical gantry router until the plurality of surfaces are substantially flat and substantially coplanar with one another.

The invention refers to a machine for 3D processing of volumetric metal objects with random shapes and sizes, in particular for thermal and/or laser cutting of holes and random contours in metal cabinets in their assembled state. The machine consist frame /1/, on the horizontally oriented beams /5/ are fixed linear guide ways, on which are placed two vertical oriented carriages /6/, wherein at their upper end the carriages /6/ are connected with a cross beam /7/ oriented toward axis X and perpendicular to axis Y, and on the cross beam /7/ are mounted at least two linear guide ways to which a horizontally oriented carriage /8/ is connected, with the possibility of movement along the axis X, as to the carriage /8/ is mounted a ram /9/, which move in the carriage /8/ with the possibility of movement in the vertical direction along axis Z.

The invention relates to a supporting device for a plurality of components (100, 200, 100*) with different geometries, in particular for a plurality of geometrically different motor-vehicle external attachments made of polymer material, having a support frame (30), a drive (40) arranged on the support frame (30) and at least two supporting groups (1, 2, 3, 4, 5) arranged on the support frame (30), wherein each supporting group (1, 2, 3, 4, 5) serves as a supporting surface for a particular component geometry, wherein each supporting group (1, 2, 3, 4, 5) has at least two spaced-apart, disc-shaped supporting elements (1, 1, 1; 2, 2, 2, etc.), the upwardly facing rim (10, 10, 10; 20, 20, 20, etc.) of each of which already has, in the unloaded state, a contour adapted to the geometry of the associated component (100, 200, 100*). By means of the drive (40), the supporting elements (1, 1, 1; 2, 2, 2, etc.) are movable such that only the supporting elements (1, 1, 1; 2, 2, 2, etc.) of a single supporting group (1, 2, etc.) protrude upwards such that the upwardly facing rims (10, 10, 10; 20, 20, 20, etc.) thereof form the supporting surface for the component geometry associated therewith.

A numerical controller includes a motion start point determination unit that calculates a cycle motion start point where the screw thread cutting cycle is to be started, an acceleration/deceleration control unit that moves the tool from the cycle motion start point to a screw thread cutting start point with motions of a plurality of axes overlapped, and a control unit that controls motions of a machining device based on control instructions received from an instruction analysis unit and the acceleration/deceleration control unit. The cycle motion start point is a point from which acceleration or deceleration of a first axis and a second axis orthogonal to the first axis is started so as to make a speed of the first axis reach a specified cutting feed speed and to make a speed of the second axis substantially become zero at time of arrival at the screw thread cutting start point.
