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 BT 130 is a table-type boring mill with a 130 mm (5.12 in) spindle and an ISO 50 taper. It is not in Union's current lineup, and the listed figures come from a third-party listing, so they describe what has been advertised and not a confirmed specification.
Travels are given as upper limits: up to 4,000 mm (157 in) of table travel in X, up to 3,000 mm (118 in) of headstock travel in Y, up to 2,000 mm (79 in) of column travel in Z, and 800 mm (31.5 in) of quill travel in W. A second group of rows gives smaller figures of 110" for X and 98" for Y, consistent with one machine built below the maximum. Tables are listed at 1,600 × 1,600 mm as standard and 2,000 × 2,000 mm as an option, with a CNC B-axis rotary table of 25,000 kg capacity.
The spindle rows need the most care. Power is listed twice, as 55 kW (74 hp) continuous and as 67 hp, and speed as 2 – 2,000 RPM through a gearbox and as 1,000 RPM. Two controls appear as well, a Siemens SINUMERIK 840D sl and a GE Fanuc 18i-M 4-Axis CNC Control. The likeliest reading is that the rows describe different builds of the model, which means the nameplate and the control of the machine on offer are the only reliable source. Peak torque is listed at up to 40,000 Nm.
The machine is listed at 80,000 Lbs with overall dimensions of 335" x 235" x 216", so foundation, crane capacity and floor space all need settling before a purchase.

Strengths & Limitations
Strengths
- 130 mm (5.12 in) spindle with an ISO 50 taper and 800 mm (31.5 in) of quill travel
- Peak spindle torque listed at up to 40,000 Nm
- CNC B-axis rotary table listed with 25,000 kg capacity
- Travels listed up to 4,000 mm (157 in) in X, 3,000 mm (118 in) in Y and 2,000 mm (79 in) in Z
- Table of 1,600 × 1,600 mm as standard, with 2,000 × 2,000 mm as an option
Limitations
- The listed figures disagree on spindle power (55 kW (74 hp) continuous or 67 hp) and on speed (2 – 2,000 RPM or 1,000 RPM), so each must be confirmed on the machine
- Two different controls are listed, a Siemens SINUMERIK 840D sl and a GE Fanuc 18i-M, so the control depends on the individual machine
- Travels are stated as upper limits; one listed machine has 110" of X and 98" of Y
- At 80,000 Lbs and 335" x 235" x 216" the machine needs a prepared foundation and heavy rigging

Frequently Asked Questions
01
The listed figures give two values: 55 kW (74 hp) continuous in one row and 67 hp in another. Peak torque is listed at up to 40,000 Nm and the taper as ISO 50. Because the rows do not agree, read the power from the spindle motor nameplate of the machine being considered.
02
Up to 4,000 mm (157 in) of table travel in X, up to 3,000 mm (118 in) of headstock travel in Y, up to 2,000 mm (79 in) of column travel in Z and 800 mm (31.5 in) of quill travel in W. A second set of rows lists 110" for X and 98" for Y, which fits a machine built shorter than the maximum.
03
Two are listed: a Siemens SINUMERIK 840D sl and a GE Fanuc 18i-M 4-Axis CNC Control. A given machine has one or the other. Check which before planning programming and post-processing, since the two take different programs and options.
04
The listed dimensions are 335" x 235" x 216" and the listed weight is 80,000 Lbs. The rotary table is a CNC B-axis unit with 25,000 kg capacity. Tables are listed at 1,600 × 1,600 mm as standard and 2,000 × 2,000 mm as an option, and one row set gives a table of 72" by 80".
