One of the big questions that has yet to be answered in full is the tooling needed for this kind of machining.
Roughing and finishing need two completely different types of boring bars. In our case for a component with a 267 mm bore, we pushed our spindle to the maximum power by using the following tools:
- Big Diameter Boring (Ø267) by HSK A63 Spindle
- Max. Stock removal per side 4 mm.
- Rough Boring bar : 3 Step Tool (4 tooth per Dia)
- Finish Boring : 4 Step Tool (4 Tooth per Dia)
We also tested CFRP tools, AM tools and conventionally built tools to be able to best support our customers with their specific problems.
