Materials for, and methods of, colorizing a metallic surface with micro-gratings using vibration cutting technologies are provided. Micro-gratings on aluminum, brass, and stainless steel surfaces can be rapidly created to effect, under illumination, at least one color observable in the visible spectrum using elliptical vibration texturing, a vibration-assisted mechanical cutting process. The modified metallic surface can display multiple visible colors, an iridescent effect caused by changes in one or more cutting parameters employed to produce the micro-gratings, the angle of illumination by an incident light, and/or the viewing angle of the surface under illumination.

The present invention provides an image engraving apparatus capable of precisely driving a stylus to improve accuracy of image engraving. The image engraving apparatus has a vibration actuator fixed to a floating base and having an output portion configured to output vibration generated by deformation of piezoelectric elements, a stylus supported with a stylus holder to be vibrated and engrave an image on a medium to be engraved, a supporting spring supporting the stylus holder, and a retainer positionally adjustably supported to the floating base to come into contact with the medium.

A disposable multi-edge carving blade contains a first end and a second end which are symmetrical to each other and are connected together so as to form a V-shaped end portion of the carving blade, wherein the first end of the carving blade has a first side face defined thereon, and the second end of the carving blade has a second side face formed thereon, the carving blade also includes two chip removing grooves correspondingly arranged beside a distal end of the V-shaped end portion thereof, and each chip removing groove has a cutting face defined on a bottom end thereof and intersecting with a rotation axis of the carving blade so that at least two cutting edges are oppositely defined beside the rotation axis.

A marking machine having a marking head provided with a percussion tool configured to alter at least partly a surface of an object to be marked, a movement device/component/unit/apparatus or the like configured to move said percussion tool along a direction of percussion, and a heating assembly configured to heat said percussion tool.

A set comprising a plurality of covering elements for floors and/or walls, wherein each covering element comprises an upper surface having a pattern and at least one distressed upper edge, wherein at least two covering elements of the set comprises substantially the same pattern, and wherein the shape of the distressed upper edge differs in each covering element of the set.

A method and an apparatus with rotating tool changer for automatically machining multiple sides of a workpiece which is trimmed and machined according to tags placed on the workpiece or preprogrammed sequence. A method that automatically selects and adjusts parametric computer machining code to machine various workpieces sizes. An apparatus comprising a handling and trimming station of parts to be machined, multiple optical, magnetic or radio-frequency identification (RFID) reading systems for processing labels or tags information for sequential workpieces machining steps, a multiple gantries computer numerical control (CNC) station for machining workpieces on various sides, multiple rotating tool changers for selecting tools used to machine workpieces, and a storage station that receives workpieces in sequential order when they have been processed. The moving gantries of the CNC station simultaneous machine multiple sides of the workpiece which in the preferred embodiment is composed of panel for making decorative items and engraved doors.

A CNC machine comprises a holder for a workpiece to be machined, a tool array comprising one or more tools, a machining arm adapted to select and use one of said one or more tools to machine said workpiece, and a marking device positionable in said tool array and selectable by said machining arm. The marking device comprises an optionally fluid-sealed housing and a marking head mounted in housing for translational movement in a marking plane. The marking head has a marking tip, being moveable in a marking direction substantially orthogonal to said marking plane for marking said workpiece. A controller is used for controlling the translational movement of the marking head and the marking pin. A communicator enables communication externally at least to operate the marking tip but also preferably said translational movement to describe the desired shape of mark to be made.
