W56HZV-17-R-0066 – Vertical Milling Machine
Question and Answers Log:
Question:
I see the solicitation now asks for something comparable to the specs listed, however, the specs were clearly written from a specific machine manual and was hoping I could find out from the requesting party exactly what model they are after so we can supply exactly what they would like.
Answer:
I don't have access to the specific model number the specifications were pulled from however, the information provided should help establish a model that's equivalent.
Question:
You specify you have 85 psi in your factory for compressed air. Can you please provide what CFM the compressed air is at?
Answer:
CFM is estimated to be 10-12
Question:
In the control section you specify; "The control Operating system shall be Windows XP, latest version and service packs." Windows XP is no longer supported by Microsoft and is out dated. Can Windows 7 be supplied?

Question:
Looking over your request on the Sol.# W56HZV-17-R-0066 , having a little trouble finding that Model. Wondering if a DMG Mori , Model # DMC65FD monoBLOCK , would be a formidable replacement? Again Thank you for your time on this matter! Kim Simons
That "model number" should not be posted. This solicitation does not call for a specific model number, only that in meets the specifications stated within. Amendment has been posted.
File details come from the government source that posted it. Updated .
