How much does the You Ji VTM850 cost?
Price estimate
We do not have a price for the You Ji VTM850 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
Linear guide ways under the table, a box way under the head: the You Ji VTM850 is the hybrid in You Ji's family of 850-class vertical machining centers. X and Y run on rolling guides for quick positioning, and Z keeps a sliding box way to take the thrust of drilling and face milling.
The envelope is the one the box-way VMC850 has. X-axis travel is 850 mm (33.5 in), Y and Z are 600 mm (23.6 in) each, and the table is 1,000 x 550 mm (39.4 x 21.7 in). The spindle is BT-40 at 8,000 rpm.
So the choice among the three series is about the kind of cutting, not the size of the part. A shop doing mostly drilling, tapping and medium milling with many short moves benefits from low-friction X and Y. If the work is heavy side milling in tough material, the all-box VMC850 is the stiffer arrangement in the plane of the table. If it is light, fast contouring, the VLM850 puts a linear guide on Z as well.
You Ji publishes a short table for the VTM series: travels, spindle nose to table distance of 100-700 mm (3.9-27.6 in), speed, taper, table and outside dimensions. Rapid rates, which are the point of linear guides, are not in it. Neither are tool capacity or spindle power. The footprint is 2,450 x 3,780 mm (96.5 x 148.8 in) with a height of 3,030 mm (119.3 in).

Strengths & Limitations
Strengths
- Linear guide ways on X and Y for low-friction positioning
- Box guide way on Z to absorb drilling thrust
- BT-40 spindle at 8,000 rpm
- 600 mm (23.6 in) of Z travel and up to 700 mm (27.6 in) under the spindle nose
Limitations
- No rapid traverse figure is published, so the gain over the box-way VMC850 cannot be read from the table
- X and Y linear guides give up some damping in heavy side milling
- Table is 550 mm (21.7 in) deep, narrower than the 600 mm (23.6 in) Y stroke can cover
- Tool changer type and capacity are not stated for the VTM series

Frequently Asked Questions
01
You Ji's key reads: VTM, X/Y-axis linear guide way, Z-axis box guide way. The VMC series is box way on all three axes and the VLM series is linear on all three.
02
No. The table gives 850 mm (33.5 in) in X and 600 mm (23.6 in) in both Y and Z for the VTM850, with a 1,000 x 550 mm (39.4 x 21.7 in) table, which matches the VMC850 row for row.
03
A BT-40 spindle with a listed speed of 8,000 rpm. The distance from spindle nose to table ranges over 100-700 mm (3.9-27.6 in). Motor power is not printed in the catalogue table.
04
Yes. The VTM1100 has 1,100 mm (43.3 in) of X travel and a 1,260 x 550 mm (49.6 x 21.7 in) table with the same Y, Z and spindle. Floor space of the VTM1100 is 2,450 x 4,180 mm (96.5 x 164.6 in).
