Re: [CAD_CAM_EDM_DRO] Inserts in the home shop

Hello Friends,
In a home shop it depends on your expectations of the finished
part AND on your machine if inserts are useful.
A wobbly machine will kill every insert within seconds. so that
obviously
becomes very expensive!
For me it took 2 month to fix the lathe and 3 days to fix the mill until
I were able
to use inserts. And there is a learning process you have to go through
before
you will be satisfied with the result.
Good Luck
Sven Peter
