5 Bridgeport Mills 1 large Sharnoa knee mill 1 auto feed Horizontal band saw	Last updated February 5, 2026

The machines:

This is one of those rare finds. Too good to pass up. Bridgeport milling machines with very little run time. Each of these machines are late 1980's to early 1990's

2 are series 2 machines and 3 are series 1 mills. 5 in total
All but one has 2H.P. spindle motor.
All with Vari drive speed controls.
60 - 4200 RPM
All have universal quick switch brand, solid tool holders.
All have CHROME WAYS. Top of the line in heavy duty construction.
All have stepper motor controls.
I would not expect any of these controllers to be in working condition today.
Each has an air actuated brake to assist in loading your quick switch solid tool holders.
One of these is a series 2 with a 5H.P. spindle and the spindle wizard option. This system uses a rotary turret to provide multiple depth stops for the air driven spindle feed mechanism. The knee is programmable with an air counter balance system and ball screw used to raise and lower the knee. High tech in its day.
There is one matching Hofmann rotary table
EACH MILL WILL INCLUDE 10 tool holders and a machine vise.

      $6,475.00 Per mill includes tooling.
      I will prepare your machine for shipping and box the tooling.

The story:

This high tech aero space manufacture closed their doors in 1993. All the machinery, parts, tooling, chairs and desks were covered and the building locked up. Today, the owner is ready to liquidate everything. The building is being sold and these machines must go. Because the tooling is scattered I can not provide a specific list of tooling except to say that the first buyer will have the best chance of getting the sizes he asks for. This business owner specifically ordered his machines with 2 H.P. spindle motors to keep the cost of electricity in check.

The controls are OEM Bridgeport stepper systems and will need to be upgraded. I have prepared 2 quotations for this. One is the cheapest and the second includes Centroid's professional console. Personally I would keep the OEM electrical enclosures and build your new controller inside. We can install the controls or you can do it yourself.

All pieces are offered as is, where is. While I have every reason to believe that all mechanical components are in tip top condition you can expect, at the very least, to replace the rubber way guards. These machines have sat idle for 18 years so you may also need to replace the spindle drive belt & servo drive belts.

AR 260 automatic Horizontal saw
with Power feed

Here is a power feed saw that he says was used once. I can believe it. There are signs of the original packing grease on the machine and no sign of ware around the push buttons. Powered rollers will feed your stock material to its adjustable stop, then clamp and begin cutting. This is mounted on wheels to provide easy movement in multiple locations around your shop. 220VAC 3 phase power.

Sharnoa SD900 mill $2,980.00

Noted for high accuracy machining with the convenience of a knee mill the SD900 is a big brute of a machine tool. X travel is at least 30" and commonly 33" with the Y axis providing 19 " of travel. 5H.P. vari drive spindle has plenty of torque for its heavy duty 40 taper spindle. 60-4200 RPM. 6" of quill travel. The LARGE electrical enclosures provide ample room for a new controller. In fact, I am currently updating its sibling mill, the SD850, in another location. Watch for that video to be completed shortly.

I can't stand behind this machine's current mechanical condition except to say that it has sat idle for the last 8 years. Prior to that I serviced the machine and its controller. It ran well at that time and it looks good today. I have noted some light rust spots on the table. This shop owner is retiring and ready to move this machine out. No tooling or vices are offered however I believe a side deal could be made for these items.
