Price estimate
We do not have a price for the You Ji HFB150 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 You Ji HFB150 is a floor type horizontal boring and milling machine: the workpiece stays on floor plates and the column travels past it. A Ø150 mm (5.9 in) spindle quill extends 750 mm (29.5 in) on the W-axis from a ram of 440 x 400 mm (17.3 x 15.7 in) that itself strokes 800 mm (31.5 in) in Z.
The travel choices show the scale. X, the column run along the floor, is offered in seven lengths from 4,000 mm (157.5 in) to 14,000 mm (551.2 in). Y, the headstock's vertical travel, is 3,000, 4,000 or 5,000 mm (118.1, 157.5 or 196.9 in). There is no table load figure because there is no table; the catalogue lists a floor plate, FT25/20, of 2,500 x 2,000 mm (98.4 x 78.7 in) and 280 mm (11.0 in) thick, and plates are laid side by side to suit.
You Ji describes the mechanics in some detail. The ram has a large cross section for rigidity. Sliding units are hydrostatic, with high load capacity. The long X drive is rack and pinion with helical gears and backlash elimination, and the Y-axis uses dual ball screws under servo tandem control to balance the headstock. The W-axis headstock is stated to be German made.
Spindle speed is 2,500 rpm. Combined reach toward the work is Z plus W, and a part further away than that needs repositioning or an extension. Motor power, spindle taper and attachments are not in the table.

Strengths & Limitations
Strengths
- X-axis travel in seven lengths from 4,000 to 14,000 mm (157.5 to 551.2 in)
- Y-axis travel of 3,000, 4,000 or 5,000 mm (118.1, 157.5 or 196.9 in)
- Ø150 mm (5.9 in) quill with 750 mm (29.5 in) W travel on a 440 x 400 mm (17.3 x 15.7 in) ram
- Hydrostatic sliding units
- Dual ball screws with servo tandem control on the Y-axis; rack and pinion with backlash elimination
Limitations
- Ram travel (Z) of 800 mm (31.5 in), shorter than the 1,100 mm (43.3 in) of the HFB180
- Spindle power and taper are not published
- Floor plates and any rotary table are separate items to specify
- 2,500 rpm top speed limits small-cutter finishing

Frequently Asked Questions
01
On the HFB150 the column moves along the X-axis and the workpiece rests on fixed floor plates, so part weight is not limited by a table. You Ji's table-type machine is the HBM130, whose rotary table carries 12,000 kg (26,455 lb).
02
A spindle quill of Ø150 mm (5.9 in) with 750 mm (29.5 in) of W-axis travel, in a ram of 440 x 400 mm (17.3 x 15.7 in) cross section with 800 mm (31.5 in) of Z-axis travel. Spindle speed is 2,500 rpm.
03
X-axis travel of 4,000, 5,000, 6,000, 8,000, 10,000, 12,000 or 14,000 mm (157.5 to 551.2 in) and Y-axis travel of 3,000, 4,000 or 5,000 mm (118.1, 157.5 or 196.9 in). The model designation encodes both.
04
FT25/20, measuring 2,500 x 2,000 mm (98.4 x 78.7 in) with a thickness of 280 mm (11.0 in). The number of plates depends on the X travel and the work, and is settled in the layout.
05
You Ji states that the sliding units are hydrostatic, that the rack and pinion drive uses a helical gear with backlash elimination, and that the Y-axis sliding unit uses dual ball screws with servo tandem control for balancing compensation.
