Bolt Circle Drilling


Many manufacturers’ products have bolt circle designs.  This part is from a family of parts with four common bolt circle design.  Our customer needed a flexible process to drill different hole sizes and different bolt circle diameters.

We discussed the possibility of drilling these holes on a lathe, but it didn’t have the capability.  A new CNC lathe could do it all, but it would require a substantial investment.  Our customer was looking for a cost effective solution that was faster than a new CNC lathe.

The Jost Solution was a flexible design that could easily changeover for different hole sizes and bolt circle produces quality holes, quickly, and below budget!
