Estimated price range
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 BF 130 is a large CNC boring mill with a 130 mm (5.1 in) boring spindle, listed in a range of sizes: the listed figures give X travel as 3,000–10,000 mm and Y travel as 2,000–4,000 mm, both configurable. It is not in Union's current lineup, and the table comes from a third-party listing, so every figure here should be confirmed against the individual machine.
Because the model was configured to order, most rows are ranges and no two machines need match. Z is listed as 1,000–2,000 mm of boring head travel, with the boring spindle extending up to 800 mm as the W axis. Spindle drive is 40–60 kW depending on application, across a 4–1,500 RPM speed range. Workpiece weight is 30,000–80,000 kg depending on the floor plate, and the machine itself weighs 35,000–80,000 kg depending on size. A B-axis rotary table of 2,000–4,000 mm diameter is listed as an option. The practical consequence for a buyer is that the model name fixes little beyond the spindle diameter. Travels, power and table have to be read off the machine on offer.
A few rows are single values. Positioning accuracy is listed as ±0.005 mm, face milling diameter as up to 630 mm, the control as a Siemens 840D sl and the supply as 400 VAC 3-phase 50 Hz. A tool magazine is listed, typically 40–80 tools. The spindle taper is listed as CAT 40, which is light for a 130 mm boring spindle and one of the first things to verify on the machine, since it decides what tooling can be carried over.

Strengths & Limitations
Strengths
- 130 mm (5.1 in) boring spindle with up to 800 mm of W-axis extension
- Listed X travel of 3,000–10,000 mm and Y travel of 2,000–4,000 mm, depending on configuration
- Workpiece weight of 30,000–80,000 kg, depending on the floor plate
- Optional B-axis rotary table, listed at 2,000–4,000 mm diameter
- Tool magazine listed, typically 40–80 tools
Limitations
- Almost every row is a range, so the model name alone does not tell a buyer the travels, power or weight of a given machine
- Spindle speed tops out at 1,500 RPM, which limits small-diameter tooling
- The listed CAT 40 taper is light for a 130 mm spindle and should be confirmed on the machine
- Machine weight of 35,000–80,000 kg means foundation work and heavy rigging for any relocation
- The rotary table is an option, not part of every machine

Frequently Asked Questions
01
They vary by machine. The listed figures give X as 3,000–10,000 mm and Y as 2,000–4,000 mm, both configurable, with Z as 1,000–2,000 mm of boring head travel. The boring spindle extends up to 800 mm as the W axis. Measure or read the actual strokes from the machine being offered.
02
The listed range is 30,000–80,000 kg and depends on the floor plate, since the part sits on the plate and not on the machine. Where the optional B-axis rotary table is fitted, listed at 2,000–4,000 mm diameter, its own load rating applies and is not given here.
03
A 130 mm (5.1 in) boring spindle with a listed speed range of 4–1,500 RPM and a drive of 40–60 kW, depending on application. The taper is listed as CAT 40. Face milling diameter is listed as up to 630 mm. Confirm power and taper from the nameplate, as one is a range and the other is doubtful in the listed figures.
04
The listed control is a Siemens 840D sl and the electrical supply is 400 VAC 3-phase 50 Hz. A site on a different voltage or frequency would need a transformer or conversion, which should be settled before the machine is moved. A tool magazine is listed, typically 40–80 tools.
