Our best estimate for a cnc boring machine in this class — not a quote from Union. Configuration moves it a long way.
Overview
The Union BF110.8 is the smaller-spindle machine of the pair it forms with the BF130.8: a boring mill with a 110 mm spindle, up to 4,000 mm of X travel, 2,000 mm of Y and 1,000 mm of Z, plus a 700 mm W-axis. It is not in Union's current lineup. The listed figures are unverified and are best used to frame questions about a specific machine.
What the 110 mm spindle buys is speed. The listed maximum is 3,000 rpm from a 37 kW drive, where the BF130.8 lists 2,500 rpm with 52 kW. The higher speed makes this machine more comfortable with smaller drills, taps and finishing cutters than its bigger relative. The trade-off is stiffness at long reach: a thinner spindle run out toward 700 mm deflects more under the same cut, so heavy boring at full W extension is not where this machine is strongest.
The work envelope is also the smaller one. The table is 1,400 x 1,250 mm, with a rotary table as an option, and the maximum workpiece weight is 10,000 kg on a floor plate. The BF130.8 is listed at 25,000 kg. Machine weight is approx. 28,000 kg, which still calls for a prepared foundation. The control is a Siemens SINUMERIK 840D sl.

Frequently Asked Questions
01
Spindle size and everything that follows from it. The BF110.8 has a 110 mm spindle, 3,000 rpm, 37 kW, up to 4,000 mm of X and a 10,000 kg workpiece limit on a floor plate. The BF130.8 has a 130 mm spindle, 2,500 rpm, 52 kW, up to 5,000 mm of X and a 25,000 kg limit, and weighs approx. 42,000 kg against approx. 28,000 kg.
02
The listed figures give X as up to 4,000 mm, Y as 2,000 mm and Z as 1,000 mm, with a 700 mm W-axis for the spindle. X is stated as an upper limit, so shorter machines may exist. Check the actual X stroke of any machine on offer.
03
Maximum workpiece weight is listed as 10,000 kg on a floor plate. The table is 1,400 x 1,250 mm and a rotary table is an option. No separate load figure is given for the rotary table, so ask for it if the machine being considered has one.
04
The listed control is a Siemens SINUMERIK 840D sl. The spindle is listed at 3,000 rpm and 37 kW, and the machine weighs approx. 28,000 kg. Confirm the control version and its options on the machine itself, as they are not listed.
