How much does the You Ji YV700 cost?
Price estimate
We do not have a price for the You Ji YV700 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
Ø800 mm (31.5 in) is the figure to remember for the You Ji YV700. That is the maximum turning diameter of this CNC vertical turning lathe, held in a 24 in (610 mm) chuck with Ø900 mm (35.4 in) of swing and 600 mm (23.6 in) of turning height.
The YV700 sits just below a break in the range. From the YV1000 upward the catalogue quotes the chuck in millimetres and the spindle changes to a 37/45 kW (49.6/60.3 hp) motor. Here the motor is 18.5/22 kW (24.8/29.5 hp) and the range 20-1,500 rpm.
Maximum loading weight is 1,800 kg (3,968 lb). A part near the full diameter is likely to be a ring, a wheel or a large flange, and on those the load limit is rarely the constraint; jaw reach and the swing are. The table gives only those two figures, so plan jaw layouts from the maker's drawing.
The machine is lower than the YV600, 4,120 mm (162.2 in) against 4,450 mm (175.2 in), but wider on the floor at 4,300 x 2,450 mm (169.3 x 96.5 in). Builds in the model key are the vertical turret (A), horizontal turret (E), horizontal VDI power turret (E+C), ATC and ATC+C. The horizontal turret family ends at the 800, so this is close to the last size where a drum turret can be had.

Strengths & Limitations
Strengths
- Ø800 mm (31.5 in) turning diameter and Ø900 mm (35.4 in) swing on a 24 in (610 mm) chuck
- 1,800 kg (3,968 lb) maximum loading weight
- Lower than the YV600: 4,120 mm (162.2 in) against 4,450 mm (175.2 in)
- Turret builds (A, E, E+C) and tool changer builds (ATC, ATC+C) are both listed
Limitations
- Same 18.5/22 kW (24.8/29.5 hp) motor as the YV500; the YV1000 moves to 37/45 kW (49.6/60.3 hp)
- Floor dimension of 4,300 x 2,450 mm (169.3 x 96.5 in) is larger than the YV600's 4,000 x 2,330 mm (157.5 x 91.7 in)
- No pallet changer build: APC starts at the 800 in the maker's key
- Speed tops out at 1,500 rpm

Frequently Asked Questions
01
Ø800 mm (31.5 in), with a maximum swing of Ø900 mm (35.4 in) and a maximum turning height of 600 mm (23.6 in). The chuck is 24 in (610 mm) and the maximum loading weight is 1,800 kg (3,968 lb).
02
The catalogue lists a spindle motor of 18.5/22 kW (24.8/29.5 hp) and a speed range of 20-1,500 rpm. The table does not state torque or gear steps. For interrupted roughing at full diameter, ask You Ji for the torque at the low end of the range.
03
When the part exceeds Ø800 mm (31.5 in), weighs more than 1,800 kg (3,968 lb), or needs more power. The YV1000 turns Ø1,100 mm (43.3 in), carries 4,000 kg (8,818 lb) and has a 37/45 kW (49.6/60.3 hp) motor, but its speed range is 1-600 rpm.
04
The floor dimension is 4,300 x 2,450 mm (169.3 x 96.5 in) and the machine height 4,120 mm (162.2 in). The catalogue table does not give weight, so floor loading needs the maker's foundation drawing.
