The rigidity answer for medium-size parts: a 1,200 kg table load and 302 N·m of peak spindle torque in a vertical machining center, with thermal behaviour engineered rather than tolerated.
What we advertise is what we are willing to sign.
The specifications below are published exactly as they appear in the technical agreement — not as they appear in a brochure.
Three things this model does better than the alternatives — and the numbers behind each of them.
147 N·m rated, 302 N·m peak, 22 / 30 kW. BT50 tooling and that torque band put this machine into genuine roughing work on medium castings, not just finishing passes.
The heaviest table load of any vertical machining center in the GA- range. Travel of 1,050 × 530 × 560 mm with heavy fixturing capacity is an unusual combination at this machine size.
Bed rigidity of 265 N/μm or better; spindle thermal growth compensated from 0.025 mm down to 0.005 mm; hollow-cooled ball screws removing around 40% of screw heat, holding lead deformation to 0.001 mm. Accuracy over an eight-hour shift is a thermal problem before it is a mechanical one.

The fastest way to lose an engineer’s trust is to sell them the wrong machine. So we say this up front.
This model does not yet have a contract-version technical agreement. That means the specifications above are provided for reference and are subject to the final technical agreement we sign with you. We have marked every single line accordingly rather than mixing them in with our contract-grade models. If you need parameters committed in writing before you order, ask us for the models that carry a signed technical agreement — there are 22 of them.
Where this model earns its place on the shop floor.
Multi-face milling and deep-hole drilling on heavy castings, where 1,200 kg of table capacity and BT50 torque are both needed in the same setup.
Bore work, face milling and thread tapping to tight positional tolerance — the case where thermal drift over a long cycle is the real accuracy risk.
Multi-face milling, deep-hole drilling and tapping consolidated onto one machine, using rigidity rather than multiple light passes to get there.
