Hello,

I have been a regular reader here for the last couple of months. This is my first post and I need you guys to point me in the right direction. I am looking to purchase a used 3-axis CNC vertical mill and need some recommendations on good machines to look into. I have up to $10k to spend now but would like to spend no more that $8500. I could go a few thousand over 10 (If I put off the purchase for a while) to get the quality of machine I am looking for.

My Info:

1. Uses: Primarily aluminum/steel/stainless steel milling, high accuracy and presision paramount, large amounts of material removal per part but MRR does not need to be stratospheric, low production levels.

2. I want a machine that will last me a lifetime with proper care and maintainance, literally. Machine must be built right and have a reputation for quality parts and workmanship, excellent reliability and high precision. Must be servicable.

3. I would really prefer a VMC or bed mill( for the additional z travel), but a big solid knee mill would probably work equally well.

4. I would really prefer a high torque 4 to 7.5hp machine. I would consider a 3hp machine but I am not sure it would work for me so I am open to suggestions here. To me more power is always better.

5. NMTB 40 or 50

6. I would really prefer a 6k rpm machine. I would consider a 4k rpm machine, but I am not sure it would work for me. Again, I am open to suggestions.

7. Belt driven

8. X travel ~30in

9. Y travel ~15in

10. Z travel I would like to be able to fit a 4th axis at a later time so I need suggestions here

11. Controller: open to suggestions. My part files are primarily solidworks, and autocad, and I have access to mastercam and delcam powermill for toolpaths.

Currently I have been looking at Tree's, Hurco's, Milltronics' and Bridgeport's. I don't have any idea how these manufacturers stack up in term of quality, reliability or precision. I have also seen Supermax, Dan Lih, Leadwell etc, but again I have no idea if they are high quality machines or throwaways.

I would like recommendations on the manufacturers and/or model numbers of machines that may fit my requirements. Also, my requirements are not set in stone, if you have other recommendations or think something sounds odd with mine please discuss. I have alot to learn so please any suggestions, critiques, concerns or insight is greatly appreciated.

Thank you very much,

Chris Skarzenski
