CNC vertical lathe
2.5-8 m VTL (milling) CNC Vertical Lathe
A vertical lathe for parts that are heavier than they are long: flanges, rings, wheels and gearbox cases. The table runs on hydrodynamic or constant-flow hydrostatic guideways, and a tool magazine turns the machine into a vertical turning centre.

Model FAQs
Questions Engineers Ask About The 2.5-8 m VTL (milling)
What spindle speeds does the 2.5-8 m VTL (milling) run, and why does the range matter?
The catalogued range is 20–1000 r/min. The span matters more than the top figure: large diameters and tough materials live at the low end where torque does the work, while small-diameter finishing wants the top end. A range that covers both ends is what lets one machine carry mixed work.
What should I look at inside the 2.5-8 m VTL (milling) beyond the spec table?
Two build points matter most on this machine: twin-ballscrew cross rail lift, bed ways laid out thermally symmetric; and table and table base cast as one thermally symmetric structure. Structure decides how a machine ages — the specification table tells you what it does new, the build tells you what it does in year five.
2.5-8 m VTL (milling) or 2.5-8 m VTL (with magazine) — which fits my work?
Both sit in the cNC vertical lathe group, so the decision is capacity and duty, not kind: put your largest part dimensions, material and yearly quantity against each specification table and one of the two will run out of a figure first. Send the drawing and we will name which of the two fits — including the case where the smaller machine does the job.
What evidence comes with the 2.5-8 m VTL (milling) that it meets spec?
Every 2.5-8 m VTL (milling) is laser-measured to ISO 230-2 over its travels, cuts a test piece that is measured rather than admired, and ships with a serial-numbered report carrying the measured values. If any line misses, the machine goes back into the shop until it passes — the report is a record, not a promise.
