How revimaxx produces large workpieces with ultra precision

The Revimaxx workshop makes extensive use of boring as a form of machining. Our machine operators do so using a medium or large Pegard machine of Belgian manufacture as well as 2 Czech Tos boring mills. But what is the added value of boring as an alternative to other forms of machining?

‘With our largest boring machine, we can handle workpieces measuring 8 by 3 by 3 metres,’ said Revimaxx managing director Johan Van Meenen proudly. ‘Those are sizeable pieces already, for sure.’

Vibrations completely out of the picture

You can use boring to very precisely create a hole with a huge diameter. This involves sinking a boring bar - using a chisel with 1, 2, or several (stepped or not) cutting edges - into a workpiece. Vibrations are completely excluded, partly because the machine itself does not move and only moves forward, and partly because there is usually a relatively small feed rate and depth of cut relative to the diameter. This implies that the machining is much more accurate than alternative machining methods.

Ultra-precise workpieces

However, it is not processing speed, but rather machining accuracy for large diameters that is the reason why Revimaxx prefers boring to drilling. With drilling, you often incur the risk that the end result will not meet high industry requirements. Holes may not be fully circular or the surface quality is less than desirable. Both operations are mostly at the very end of the production chain, so the potential cost of imperfections can quickly add up. This is why Revimaxx consciously opts for boring because it is the only way to guarantee the predetermined accuracy.
