WITh the MSD diameter gauges,
Zumbach electronic has introduced a
new series of measuring heads for on-line
diameter and ovality measurement and
control.
This new line complements 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.
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.
unique measurement 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.

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:
• 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

The TCD V-9 is
ideally suitable for
in-house polishing
and regrinding of
round tungsten
carbide dies, but can also be used for
polishing heading dies and extrusion dies.
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°
