Technology news Maximise stock removal performance

THE better a material can be machined, the more cost-effective the associated process chains are for manufacturing operations. For this reason, Ugitech constantly develops its stainless and easy-to-machine bar steels further. The latest result is Ugima®-X – the third generation of the special steel that has now proven itself for 30 years. With Ugima-X, the company in the Schmolz + Bickenbach Group offers customers a long-term advantage in the market, provided among other things by longer service lives of the tools being used. 30 years after Ugima and 15 years after Ugima HM, Ugitech has reached the next milestone of its special steel development. Ugima-X enables extremely high cutting speeds alongside low tool wear. In figures: the new steel grade extends tool service lives by 25 to 50 per cent. Among other things, this is made possible by the introduction of very fine oxide inclusions into the liquid metal in a perfectly controlled composition. The stainless bar steel thereby retains its corrosion resistance and becomes much easier to machine. The third Ugima generation fulfils the requirements of the latest CNC machinery with speeds up to and above 10,000 revolutions a minute. Ugitech customers thus benefit from extended tool life, improved cutting The PWC system performs wire cleaning and polishing in-line with the wire-drawing machine. Cleanliness permits direct wire brass coating, copper coating, galvanising, wire cleaning prior to heat treatment, etc. The system incorporates new technology that enables normal cold plant water to be converted into a cleaning medium, generating high-pressure wetting/contaminants extreme pressure extrusion/hydro- dynamic cavitations displacement and contaminants flush out, used to clean drawn wire at high speed in a completely green application,

HM, whereby side effects such as cold cracks caused by the lower and controlled sulphur content are further reduced. Ugima-X 4305 is resistant and compatible with all liquids, lubricants, oils and greases that are used during the machining process. Compared to Ugima 4307 it has been possible to increase the average machinability of Ugima-X 4307 by ten per cent, whereby the dispersion of its industrial machinability has been significantly improved. Ugitech – France Website : www.ugitech.com The PWC system effectively removes lubricant residue from the base material and is particularly recommended by Decalub for cleaning applications with wires drawn in severe conditions. For decorative mirror reflective wire applications, the system can be used with a light emulsion diluted at 3-5 per cent concentration. The PWC unit is compact and can be easily installed on the finishing/last block of a drawing machine. Decalub – France Website : www.decalub.com

fragmentation and added reliability in production planning. Ugitech offers Ugima-X in the three versions of 4404, 4305 and 4307. The three materials all have higher machinability than their predecessors with otherwise identical properties. With Ugima-X 4404, users benefit from improved properties in all areas of the machining process. During turning, an increase of 15 per cent compared to Ugima 4404 has been achieved, and during drilling it has been possible to increase machinability by 20 per cent. When it comes to turning, Ugima-X 4305 is slightly ahead of Ugima 4305
