Tool adds extra NC axis for contour
boring
Electronically guided boring tool system adds an extra NC axis on machine tools for jobs such as contour turning on joint bearings and valve seats or machining grooves in valve housings.
With Mapal Tooltronic system providing an additional NC axis, actuating movements are easily and reliably produced by the inductive transmission of power and bi-directional transmission of energy on machining centres and on special machines The system, shown at EMO 2007, opens up new areas of applications in numerous production areas in bore machining

Form milling cutters offer 30% time saving
Wear-resistant PCBN form milling cutters produce such high surface qualities that the time spent for final manual polishing can be reduced by 30 to 50%.
Tool clamping cartridges fit minimal lubrication
To put minimal lubrication quantity technology into practice, many institutes and research groups have dealt with specific questions and solutions, but a tool supplier claims to show the way.
Machining of any contours, recesses and non-cylindrical bores is as viable as closed loop systems for blade adjustment or the simple manufacturing of families of parts with numerous variations.
Typical machining examples include the following.
* Contour turning on joint bearings and valve seats.

High performance reamers reduce machining times
High performance reamers' high cutting speeds and, because of the multiple cutting edges, very high feed rates bring extremely good reductions in machining time.
* Grooves in valve housings.
* Actuating movements to carry out roughing and finishing operations with a tool.
Combined with the modular design this flexibility in production counts for a great deal, particularly for small and medium size batches but also in manufacturing special machines and prototypes.
As a result of new developments in the electronics area, today the connection to the machine tool is irrespective of manufacturer, type or version of the machine control, said a report sent to manufacturingtalk.
This advance allows and easy and fast implementation and programming, particularly in the area of excentric actuating tools.
In addition new solutions for protecting the stator in the working area on machining centres have been developed.
The components required for the inductive transmission of energy and data are not totally resistant to wear and tear from chips and coolant when the parts are being pre-machined or re-worked.
The worn or faulty stators can either be inexpensively replaced by means of a simple plug-in system or protection directly provided in the machine's working area.
Depending on the machine, this involves protecting the stator with an automatic cover.
The broad range of applications, the reduction in machining stations and the minimising of the number of tools required make the Tooltronic system an attractive NC axis for use in practice.
The company URACA Pumpenfabrik and Co KG in Bad Urach, Germany, for example, uses Tooltronic on a machining centre for machining pump and valve housings.
For this the flanged linear actuating tool machines various contours in different parts in high quality stainless steel, both the roughing and the finishing operations, with the following machining values.
* Roughing.
n = 850 rev/min.
f = 0.3mm/rev.
ap = 1.5mm.
* Finishing.
n = 750 rev/min.
f = 0.12mm/rev.
ap = 0.25mm.
