Thanks for all the replies
I am going to use a general purpose cutting fluid to start with.
Not really sure whether I will be able to cope with wet swarf so I will try it first.
If I am going to keep using coolant I will swap to a product called Alusol which is made especially for Aluminium but can be used as a general coolant.
Reason for not trying it first is the cost, $200 for 20 Litres which is a bit expensive if I decide not to keep using it. |
