Know how in tool engineering

KomTronic®  u axis systems

 

 

Describes that type of intelligence which can use electronic and data-processed elements, in conjunction with expertise in mechanics, to create a system known as 'mechatronic'. However, this kind of know-how in tool engineering also includes the use of innovative tools or tool systems, in the form of intelligently crafted components. With the arrival of the U-axis system from KOMET®, this know-how can be clearly measured, as can be seen at the KraussMaffei plant in Treuchtlingen.

 

 

As far as the KOMET KomTronic® U-axis system is concerned, 'know-how' is demonstrated in the control cycle employed in machine control systems. A compact facing head with single slide is driven by means of a servomotor and threaded spindle. The power supply for the electronic system and the drive is transmitted to the contact-free and inductively to the U-axis system. Data exchange is also inductive. This means that the KOMET KomTronic®  U-axis systems provide automatically exchangeable and freely programmable NC axes, with a cutting edge that can be dynamically adjusted during machining.

 

Machine changes reduced

 

At KraussMaffei, this 'know-how' can be seen in connection with the U-axis systems from KOMET® which use intelligent component machining in the manufacture of components for machinery used in injection moulding, extrusion and reaction engineering. According to the conventional method, complex components such as adapters for double screw extruders used to be machined in lathes and milling machines, involving several alternate operations. 'Spectacle' bores, with their eccentric centres, placed high demands on conventional lathe machining and, because of the unbalance involved, only allowed moderate cutting speeds.

 

When the automatically exchangeable KOMET KomTronic® U-axis is used in the machining centre, the otherwise several machine changes can be reduced to two. It is now possible for the external diameter to be prepared in a lathe and for the component to then be transferred to a machining centre where the finish machining is performed in one clamping operation. In this way, 'know-how' in tool engineering can be measured from the reduced tooling times (because changeovers are no longer required) and from the shorter processing times, which in turn allow stockholdings to be reduced. The higher cutting speeds used on the workpiece which is statically clamped in the machining centre mean that essential operating times can also be slightly reduced. The improvement in quality can also be measured because tolerance fluctuations, which previously were a necessary accompaniment to frequent changeovers, are no longer a consideration.
