Machining cast iron spool bores
A common problem when machining spool bores is that rings are produced in the bore by the rough pass reamer.
The following manual removal of these rings prior to finishing/assembly is a time-consuming and costly process.
A new patented process and tool technology eliminates the rings, and results in considerable savings.
Tool supplied by UNIMERCO:
Chips are pushed out automatically while drilling, and no rings are produced by the rough pass reamer.
Tool by other supplier:
The rough pass reamer produces rings in the bore that need to be removed manually prior to finishing/assembly.
