Taking care of small diameters

In the range of 0.40-6mm Bremer has developed a fully automatic machine, the KPM4AC.

At first the dies are automatically processed to the meeting point. After the conical section is worked, the dies are automatically transferred to the calibration station, which calibrates the bearing section of the die with an accurate tolerance of 0.001mm. The system continuously checks the bore diameter and the whole cycle which ensures very close tolerances for radii angle and bore diameter. These latest developments can elimi- nate the human factor and produce a perfectly controlled die quality. To increase customer service, and to provide optimum technical support to all Asian customers, Bremer also has two agent offices in Asia, in Osaka, Japan, and Shanghai, China.

Increasing manufacturing efficiency and product quality is ever-important in these competitive times. The cost and the quality of products are essentially determined by the dies used and demand resulting from this, with regard to improved geometric drawing parameters, presupposed a sustained further development of the drawing die processing machines currently in use. There are two new developments in the wide range of tungsten carbide die working machines from Bremer GmbH in Germany. The company has developed the new KSP1 and EK2000F machines, especially for small diameters in the range of 0.12-1mm.

Both types of machines are using modern computerised technologies and built-in electronic systems.

Handling fine wire applications

Experience is golden! With more than 25 years’ experience, Pleuger is one of the leaders for hot-drawing machines for noble materials like gold, silver, platinum and compositions.

Huestis has introduced a compact fine wire pay-off for strand annealing furnaces.

The FWP1000 is designed to handle fine wire appli- cations with very low process tension.

The drawing process usually starts with Ø 0.6mm – outlet of the extrusion line – and ends at about 2mm or below 1mm, d e p e n d i n g on customer requirements.

The stand incor- porates an AC variable speed drive and an integral dancer utilising a dancer duty potentiometer. an adjustable counterweight, the unit is capable of handling fine wire as small as 0.005" diameter. Combined with

The time-saving drawing process is very gentle to the surface of the material and there are a number of advantages in comparison to the standard cold-drawing machines. Pleuger machines – one of the leaders for hot-drawing machines ▲

Mini spooler from Huestis

Built for maintenance free operation, the stand uses lightweight aluminum sheaves with ball bearing and hard coated v-grooves. Quick lock arbor collars allow for spool changes without tooling. The dog pin plate includes an adjustable dog pin. Extremely compact, much less than two square feet, the design allows for single or multiple station installation.

Both the drawing temperature and speed are adjustable.

In addition to those drawing machines Pleuger, based in Altena, Germany, also produces pay-offs, take-ups, wet and dry-drawing machines, spooling machines and hot-straightening machines for special materials.
