About this machine
This Union BFT 80 3.1 is a used horizontal boring mill — sometimes referred to as a table boring machine — dating from 1986 and currently located in the Netherlands. Horizontal boring mills are precision machine tools designed for boring, milling, drilling, and tapping large or heavy workpieces that must remain stationary on a table while the spindle head moves to perform the work. Union is a well-established German manufacturer of heavy machine tools with a long history of producing horizontal boring and milling machines for industries such as energy, aerospace, heavy engineering, and general manufacturing.
The machine is built around an 80 mm diameter spindle with an ISO 40 taper and a maximum spindle outreach of 710 mm. The working table measures 1,120 × 1,000 mm and provides three axes of travel: 1,000 mm cross travel (X-axis), 1,600 mm longitudinal travel (Z-axis), and 1,000 mm vertical travel (Y-axis). The distance from the table surface to the spindle centreline ranges from 0 to 1,000 mm, giving the machine considerable flexibility when positioning workpieces of varying heights.
Spindle speed is selectable across 24 steps ranging from 8 to 1,600 rpm, making the machine suitable for both heavy roughing cuts at low speeds and lighter finishing operations at higher speeds. Feed rates are continuously variable from 1 to 2,500 mm/min, and rapid traverse is rated at 3 m/min. The main drive motor is rated at 11 kW and the machine is configured for 380-volt supply.
The overall footprint of the machine is 5,500 × 3,200 mm with a height of 2,800 mm, and the total weight is approximately 9 tonnes.
Included with the machine is a facing head with a diameter of 460 mm and a stroke of 180 mm, a three-axis Heidenhain digital readout system covering the X, Y, and Z axes, tool clamping, guideway protection, a pendant control unit, and cooling equipment. A universal milling head is available as an option at additional cost. The seller describes the machine as being in good condition.
