Price estimate
We do not have a price for the Republic Lagun VBMA-850 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Republic Lagun VBMA-850 is the smallest of four VBMA vertical bed mills and the only one listed at 5,000 rpm. It is a 3 axis CNC bed mill with an NST# 40 spindle, a 5 HP (3.7 kW) motor and travels of 32 in (813 mm) in X and 18 in (457 mm) in both Y and Z.
A bed mill keeps the table at a fixed height and moves the head, and this one still thinks like a toolroom machine. The spindle has a quill with 5 in (127 mm) of travel. There are hand wheels on X and Y and a hand lever on Z, with a manual pulse generator listed as an option, so a simple facing or drilling job can be done without writing a program. For programmed work Lagun Engineering states that Fanuc 0i-MF controls are standard, carried on a pendant.
The table is 12 x 50 in (305 x 1,270 mm) and rated for 1,102 lb (500 kg). Its long, narrow shape favours bar-shaped parts, plates and a row of vises over deep fixtures, and it is longer than the 32 in (813 mm) X travel, so not all of it can be reached by the spindle. The maker lists positioning accuracy of 0.0004 in/ft and repeatability of 0.0002 in/ft.
Construction is conventional and heavy: stress-relieved Meehanite castings, hardened and ground box ways lined with Turcite, ball screws on all three axes with AC brushless servo motors, and a counterweight for the head. Hi-Low back gears are provided for heavy cutting. The feature list says the machine is arranged for 3/60/480 volt operation, which is worth checking against the shop supply before delivery.
