Mill for sale! (update: SOLD!)

Posted by 3ricj on 16 April 2011

A few weeks back we had an amazing garage sale here at HBL. I wanted to offer a huge thanks to everyone who showed up to help out! Thanks!

However, we still have one lingering toy - - An amazing mill. This device needs a good home. We purchased this mill several years ago - - it was our first mill, and we used it quite a bit for all sorts of projects. It's a large beast - - very stiff - - it can really remove some massive amounts of material. Along with the size, comes very clean cuts. One of the core reasons we purchased this mill and not a small desktop mill was our desire for high quality cuts. Benchtop mills are not very rigid - - they flex a bunch while cutting, and this can cause 'chatter' which impacts the accuracy and quality of the cut. This mill does not suffer from this problem, due to it's size and mass.

Anyway, back to my point. We still have this mill, but we also just purchased a fancy pants cnc mill. Thus, we don't need our trusty standby any more. We've treated it with care and love.. and even added our own glass scale DRO to the system. If you are considering taking our lovely mill home with you, here's some of the highlights:

- ~24x 14x19" of travel.
- about 6 tons
- Will fit through a 8x8 doorway.
- We have a relationship with a rigger who can move it. Cost of moving it is dependant on distance, but something on the order of a several hundred dollars (we paid ~500 to have it brought here from Everett, but rigging costs have gone up a bit)
- 240volt, 3 phase (but could be used on single phase with a phase converter, not included)
- NMBT 50 taper, with LOTS of toolholders included. The tool holders alone are worth a grand or two; no tooling is included.
- Something on the order of 5ph motor, max of 1000RPM.
- Manual transmission - so at low speeds this machine has super torque.
- power feeds on all axis.
- Meister 3-axis BC10M DRO, with glass scales. It does advanced mathematics for you, so says the manual. We paid ~1500 bucks for the DRO system.
- Has some minor oil leaks which we've tried to repair, but it's never seemed worth it to rebuild the seals on the spindle (which is working fine otherwise).
- There is an issue with the gibs which reduces the effective longitudinal travel to about 2/3 of the factory specification of 33 inches, but we've never found this issue preventing us from machining anything. This is likely repairable if the table is removed, but it weighs about a thousand pounds, thus... we've not bothered.
- *FULL MANUALS*
- about 5 gallons of way oil to feed the machine as needed (will likely last a year or two depending on usage of the mill)
- Asking price: $2,000
- Photos can be found here: http://www.flickr.com/photos/3ricj/sets/72157626511965684/
- When we purchased the mill in April 2006, we took some photos: http://www.flickr.com/photos/3ricj/sets/72057594105800022/
