An X-ray anode is produced by scoring at least a region of a surface of the anode, on which electrons are incident, with a number of defined microslits, thereby making the surface, or at least the region thereof, highly thermally stressable.
摘要:
A wire cutting device (3) for cutting a wire electrode (5), used to generate an electric discharge between it and a workpiece (W), comprising a drive gear (12), a follower gear (13) which meshes with the drive gear and is shiftable in its axial direction relative to the drive gear, an adjustable bias mechanism (17) which presses the follower gear against the drive gear in order to accommodate wire electrode of various diameters, materials and conditions, take-up rollers (10a, 10b) which feed spent wire electrode between the drive gear and the follower gear, and a drive mechanism for driving the drive gear such that the peripheral speed of the drive gear is greater than the speed at which the wire electrode is fed out by the wire take up device. The wire electrode, pinched between the drive gear and the follower gear, is held in place between two adjacent teeth (13d, 13e) of either the drive gear or the follower gear, and the portion of the wire electrode which is held in place is pressed by the teeth (12e) of one gear into the teeth of the other gear, and is broken by means of tensile force. The pressing force of the biasing mechanism is adjustable by means of an adjustment screw (17e).

An auto-removing assembly is used for a wire electric discharge machine having an upper positioning head, a lower positioning head and a metal wire and has a blowing device, a suction device, a tension device, a fuse device and a transporting pipe. The blowing device is set near a front side of the metal wire and has a first guiding block and a first air source. The suction device is set near a rear side of the metal wire and has a second guiding block and a second air source. The tension device is set between the blow and suction devices. The fuse device is set near a left side of the metal Wire and has a pressure pump and a fused head. The transporting pipe is set above the suction device and aligns with the suction device to receive the fused metal wire.
摘要:
Cutting device for spark-erosion machine wires in which, after passing through a machining region, the wire-electrode is cut up into sections which are disposed of as waste products into a recovery receptacle. The device comprises electrical contacts connected to a voltage/current source. The wire is subjected to a dielectric fluid whose flow rate is sufficiently high to generate a turbulent flow regime and cause random lateral movements of the wire which sporadically brushes against the contacts.
摘要:
The invention relates to an improved manner of recovering the used electrode wire discharged from an electric discharge machine (EDM). A more detailed object of this invention is to provide an efficient and effective system for electrode wire scrap collection, including cutting the electrode wire discharging from the EDM into many small separate pieces and collecting there pieces randomly but compactly packed in a removable container proximate the EDM.

Wire cutting apparatus which includes a mechanism for conveying an electrode and cutting device having rotary cutting elements and a tender tool. A post generator is electrically connected to the cutting elements and the counter tool for purposes of supplying power to the spark erosion machine. The cutting elements are electrically insulated with respect to the drive shaft thereof and the service of the counter tool is electrically insulated relative to the mounting support thereof. Additionally, there is provided an electrical connection which constantly forces the rotary cutting elements and the counter tool to the electrical potential of the electrode.
摘要:
An apparatus and method is disclosed for the automatic treatment of workpieces with the aid of numerically controlled wire erosion machines. When an end point of a contour is reached during the treatment process, the drive and guide system for the wire-like or strip-like electrode is disconnected and beneath the workpiece the electrode is clamped by means of two feed rollers and provided with a groove by a grooving device. Then the upper drive device is switched on again and the electrode is broken off at the groove point. Following the positioning of the workpiece, the beginning of the electrode is threaded into the new starting bore of the contour by means of the two feed rollers, is gripped by a gripper following the workpiece, and is fed to the upper drive device.
