Dear Sir/Madam,

We are interested in your opinion on the selection of a new machining center for our toolroom. Our toolroom manufactures rubber injection molds ranging in size from 100x100 to 600x500 mm, with a required final accuracy of 0.01 mm. Currently, we have the following machines in our toolroom:

DMG Monoblock 60 (year of manufacture: 2007)
DMG DMC 1150V (year of manufacture: 2016)
Makino EDAF 3 (year of manufacture: 2020)
Makino U6 Heat
Fanuc Robodrill (year of manufacture: 2022)
We are considering the purchase of a new machine and are deciding between:

DMG Monoblock 75 2nd generation
Makino D500
The DMG Monoblock 75 features the Haidenhain 7 operating system, which is familiar to me and facilitates the production of complex parts. The Makino D500, on the other hand, utilizes their P6 control system with Fanuc control, offering numerous options, but its user interface is unfamiliar and demanding for me.

Specifications for the DMG Monoblock 75 machine (2nd generation):

Which Machine would you choose or do any of you have experience with both machines?
I know that both machines are excellent, which makes the decision even more difficult.

Yours faithfully,
Matej
