An engraving system using a laser as a tool includes a laser cabinet with a three-point suspension system for mounting the cabinet on a surface such as a table. The three suspension points are arranged in a triangle with at least one of the suspension points being either in the front center or rear center of the field of translation of the engraving tool in the xy plane. While the other two suspension points are mounted in either the left and right front corners of the field or the left and right rear corners of the field or close to those locations. Using the three triangularly arranged suspension points, at least two of which are independently adjustable in elevation, the laser cabinet can be elevated and oriented so as to maintain the plane of the tool translation field parallel to the target surface of the workpiece during an engraving operation. Where the tool is a laser, the cabinet also carries a gas laser tube and an optical system for directing the output thereof to a nozzle aimed downwardly along the z axis and equipped for programmable translation in the xy axis field.

A rotary laser engraving device for retaining and rotating an object for engraving includes a frame, a first support assembly and a second support assembly mounted on the frame. To support the object the first support assembly includes a set of driven rollers and the second support assembly includes a set of free rollers, each being diagonally offset from the frame. The second support assembly is configured to slidably move on the frame to vary a longitudinal separation between the driven rollers and the free rollers. The second support assembly further includes a vertical adjustment assembly configured to move the free rollers vertically to vary a vertical separation between the driven rollers and the free rollers. In some aspects, the first support assembly also includes a fixed vertical adjustment assembly configured to move the driven rollers vertically to vary a vertical separation between the driven rollers and the free rollers.

Disclosed is a scribing or engraving tool for use to mark, scribe or engrave using a a CNC, engraving or other automated machine. More particularly some examples of the invention include a coolant passageway for providing coolant to the stylus, and others provide a second spring which engages when desired for applying more pressure to the toolbit when desired. In yet another embodiment a coupling system may be used to provide for the rotation of the stylus holder and stylus to provide for engraving.

A processing apparatus for performing not only cutting and drawing, but also other processing, and a cartridge used for the processing apparatus are provided. The processing apparatus includes a first cartridge including: a first processing tool to form a machining mark by grinding or cutting a surface of a sheet-like object; an actuator to operate by an external power supply and drive the first processing tool; and a first housing to accommodate the first processing tool where a tip of the first processing tool is exposed and accommodate the actuator. The processing apparatus also includes a carriage including a mounting section which the first cartridge is detachably mounted; a transfer mechanism to move the object and the carriage relatively to each other; and a control circuit to control driving of the transfer mechanism to form the machining mark on the surface of the object by the first processing tool.

The invention relates to converting a ball and socket style vise into a positioning vise. Jewelers and hand engravers and metal working artists utilize traditional ball vises for holding and spinning an object that is being worked on. The present invention provides a way to retrofit these traditional ball vises with a linear positioning top portion assembly.

A lifting structure of an engraving machine is provided. A lifting platform of the engraving machine has four pivot holes each provided with a screw seat, and is mounted with a shaft seat having a drive gear. A sprocket is provided under each screw seat. A driven gear is provided under one of the sprockets to mesh with the drive gear. The sprockets of the pivot holes are connected by a chain. The screw seat includes an upper screw sleeve, a lower screw sleeve, an upper thrust bearing, a lower thrust bearing, and a spring. The lower screw sleeve is rotatable in the pivot hole through the upper thrust bearing and the lower thrust bearing. The spring is located between the upper screw sleeve and the lower screw sleeve. Two screws pass through the upper screw seat and are screwed to the lower screw seat, respectively.

A motor fixing structure of an engraving machine is provided. A lifting platform has a through hole, at least three protruding walls spaced and arranged around the through hole, and notches each defined between every two of the protruding walls. The outer side of each notch is provided with a clamping block. The lifting platform has a radial guide hole corresponding in position to the clamping block. The clamping block has a vertical aperture. The bottom surface of the lifting platform has an adjustment seat with a peroration. The protruding walls are fitted with a turning disc. The turning disc has at least three oblique curved holes. The turning disc is pivotally connected with a shaft. A drive rod is screwed to the shaft. A quick release assembly is inserted in the corresponding oblique curved holes, the aperture and the guide hole for tightening or loosening the clamping block.

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.

An engraving machine is disclosed. The engraving machine may have a housing and an engraver located within the housing. The engraving machine may have a slot disposed on the housing for receiving a cartridge including an offboard item to be engraved. The engraving machine may have an onboard storage configured to store a plurality of tags. The engraving machine may have a carrier for receiving the cartridge through the slot and for positioning the cartridge relative to the engraver. The engraving machine may have a pick mechanism for selectively retrieving a tag from the tags stored in the onboard storage and for positioning the tag relative to the engraver. The engraver may engrave the offboard item or the tag based on a user selection.
