Dies, and die processing equipment

EDER offers easy to operate standard-, semi- and fully automatic machinery, ready for operation, single machines or complete workshop lines for the production and reconditioning of ultra hard precision die tools for the wire and cable industry. of drawing dies is essential to maintain a consistent high quality wire, enabling longer uninterrupted wire drawing processes,improvedperformance and higher productivity. Eder Engineering has always been involved in advanced diamond/PCD die working equipment, offering universal flexibility and highest possi- ble efficiency particularly in machinery for reconditioning and production of diamond- Regular reconditioning

and PCD dies. Eder’s latest development in this respect is the USP-Twin concept, believed to be the first single operator ultrasonic die-processing machine with two workstations. While ultrasonic machines in general are needed to work the conical die-portions, high- speed mechanical wire-type conceptions are used to calibrate and polish the cylindrical die bearing. The majority of ferrous wire is still mainly drawn using tungsten carbide (TC) drawing die-tools. TC dies need totally different working methods and machines from diamond- and PCD dies. For the average TC die user, dealing with frequent changes in die-bore diameters and a wide size application range, Eder has developed the semi-automatic ETC-1/ HF. This unit can quickly grind and polish both the conical and cylindrical die bore sections using a high frequency electric work spindle and an easy to use stock removal adjustment. Average all-inclusive die processing times are between 3 and 10 minutes. Wire drawing plants dealing with tungsten carbide dies in near identical bore-sizes and/or similar stages of wear, however, are more efficient using fully automatic equipment. In cooperation with AGIR-France, Eder offers automatic machines for all usual sizes of round tungsten carbide wire drawing dies. All operations are managed by an OPLC combined with an intelligent program. According to the type of the TC die-nib

material to be processed and the kind of operation chosen, the OPLC allows program adjustment to optimise the production or reconditioning of TC dies within the indicated work range. For processing TC dies with a dia- meter between 1mm and 6.5mm, model TCLD-C-CNC for producing or reconditioning of the conical die- portions is available, while another model, TCLD-B-CNC provides precise processing of the cylindrical bearing. Both TCLD machines can operate in an in-line mode, by means of an intelligent robot-connection. Steel cord wire producers and other special plants use tungsten carbide dies with small bore-sizes. For these customers Eder-Austria can offer a TCSD-CB-CNC that can work both the conical die-portions and the cylindrical bearing part in a diameter range between 0.1 to 1.5mm with highest possible precision. well maintained diamond, PCD or TC wire drawing dies produce longer uninterrupted runs, excellent wire surface quality and improved performance, leading to considerably higher outputs and avoiding the 20 to 40 minute downtime that results from the change of a die set in wire drawing machines.
