Hi,
The below is a company that offers a small hardinge type chucker (Not sure if he uses Hardinges or not)......I know his machines are very affordable and he has some small footprint machines that should be able to get your door, but not sure.
Babin Machine Tool
14 Upland Rd
Brockton MA 02301
Ph # 508-588-9189
I hope this helps !!
Sincerely,
Todd |
