New gauges based on linear sensor technology

unique technology for products up to 200mm external diameter: • A new product line with two-coloured LeD light sources allowing simultaneous scanning in each axis (XY*) and trouble-free measurement even with product vibration • Integrated extraneous light filters prevent occurrence of measurement errors that, to date, seemed unavoidable • perfect performance even with reflective surfaces thanks to the use of different colour lighting for each measurement axis * This new concept allows even a 4-axis measurement of products up to diameter 54mm.

Both reduction zone parallel cylindrical portions with same angular pin can be worked upon, whilst both chuck rotation and spindle reciprocating speeds are variable and adjustable according to the die sizes. Glass protection will be provided for user protection. Consumables supplied free of cost for 300 dies are: • Diamond paste/suspension • Diamond angular pins • Steel pins of 3mm and 6mm in 6° and 12° Ajex & Turner – India Website : www.ajexturner.com

WITh the MSD diameter gauges, Zumbach electronic has introduced a new series of measuring heads for on-line diameter and ovality measurement and control. the high-precision laser diameter measuring heads of the oDAC® series. The MSD models achieve their ideal efficiency in terms of price and performance specifically for applications in the plastics, rubber and cable industry for extruded tubes, pipes, hoses, cables and similar. This new line complements

The experience of 57 years with on-line and off-line measurement and control technology has led to a product characterised by the most current and sophisticated technology and functionality as well as by the well-known Zumbach accuracy and reliability. Thanks to this linear sensor technology (patent pending), it was possible to build very compact yet accurate measuring heads. Ajex & Turner has developed a new carbide die polishing and re-cutting machine with a high frequency spindle. Suitable for repair and production of round tungsten carbide drawing dies with bores ranging 0.5-25mm ∅ , this advanced conception allows it to grind and polish both the conical and cylindrical parts of die geometry. The air-driven grinding spindle offers 60,000rpm with true running, and with an accuracy of 0.005 microns the spindle with the variable speed has following advantages:

New polishing machine from Ajex

• high speed provides more accuracy in roundness of dies

• Superior surface finish • No unequal bearing length • A close tole-

rance of 0.005 microns can be achieved • high production levels • Good quality dies provides good quality wire with mini- mum inven- tory The TCD V-9 is ideally suitable for in-house polishing and regrinding of round tungsten
