How much does the You Ji YH15 cost?
Price estimate
We do not have a price for the You Ji YH15 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 YH15 is a compact CNC horizontal turning lathe with a 6 in (152 mm) chuck, an A2-5 spindle nose and an 8-st. turret. It is the smallest machine in the YH series and the only one with a chuck this small.
The working envelope is short and small: Ø190 mm (7.5 in) maximum turning diameter, 120 mm (4.7 in) maximum turning length, Ø250 mm (9.8 in) swing. Bar capacity is Ø42 mm (1.7 in). A turning length of that size means the YH15 is a chucker and short-bar machine for bushings, fittings, small flanges and pinion blanks, not a shaft lathe.
What You Ji stresses on the product page is cycle speed. Tool change time is given as 0.3 sec, and rapid traverse as X/Z 18/30 m/min on linear guide ways. The spindle runs 1-4,000 rpm on a 7.5/11 kW (10.1/14.8 hp) motor. On parts this small most of the cycle is tool indexing and positioning, so those figures matter more than motor power.
The maker also points to the footprint for automated lines, quoting 1.7m x 1.45m of floor space; the catalogue table lists machine length as 2,780 mm (109.4 in), width as 1,440 mm (56.7 in) and height as 1,685 mm (66.3 in), so the longer figure presumably includes equipment beyond the base machine. The C-axis function in the YH key starts at the YH21, so this model is a two-axis lathe.

Strengths & Limitations
Strengths
- Tool change time of 0.3 sec and rapid traverse of X/Z 18/30 m/min, as stated by the maker
- 1-4,000 rpm spindle with a 7.5/11 kW (10.1/14.8 hp) motor
- Machine width of 1,440 mm (56.7 in) and height of 1,685 mm (66.3 in) suit line integration
- Ø42 mm (1.7 in) bar capacity through an A2-5 spindle nose
Limitations
- Maximum turning length is only 120 mm (4.7 in)
- Turning diameter is limited to Ø190 mm (7.5 in)
- No C-axis: the maker lists the C-axis function for the YH21 and upward
- 8-st. turret, where the larger YH models have a 10-st. turret

Frequently Asked Questions
01
Up to Ø190 mm (7.5 in) in diameter and 120 mm (4.7 in) in length, with a Ø250 mm (9.8 in) swing. The chuck is 6 in (152 mm) and bar capacity is Ø42 mm (1.7 in).
02
You Ji states a tool change time of 0.3 sec and rapid traverse of X/Z 18/30 m/min on heavy duty linear guide ways. The spindle range is 1-4,000 rpm.
03
No. The YH model key lists the C-axis function for the YH21 and upward. The YH15 is listed with an 8-st. turret and no driven-tool option in the catalogue.
04
The catalogue table lists a machine length of 2,780 mm (109.4 in), a width of 1,440 mm (56.7 in) and a height of 1,685 mm (66.3 in). The product page separately quotes 1.7m x 1.45m of floor space, so confirm which figure applies to your configuration.
