SKB “Stankostroenie” offers double-column machining centers designed for large-part machining. The stability of the double-column design and the overall weight of the machine provide exceptional accuracy and outstanding surface finish capabilities.
With the double-column design, there is less tool deflection and less vibration compared to a single column CNC machine and less thermal deformation due to the fact that the heat only affects the bridge structure in a straight line instead of occurring on both the X- and Y-axis. Another advantage is the fact that the spindle is closer to the mass of the machine on a double-column machine, which provides increased rigidity.
Modular design concept allows us to offer various double column machine modifications to our customers.
DOUBLE-COLUMN MACHINING CENTERS
VH1250 is 5-axis double-column machining center designed for complex, large-part machining made of hard-to-machine materials, such as titan and heat-resistant alloys. The machine’s rigid cast iron construction provides a very stable cutting platform.
VH1250 features a vertically traveling crossrail (Z-axis) and a rotary table providing multisided high-accuracy machining in a single-setup.

Features:
The VH1250 is 5-axis double-column machining center designed for complex, large-part machining made of hard-to-machine materials, such as titan and heat-resistant alloys. The machine’s rigid cast iron construction provides a very stable cutting platform.
VH1250 features a vertically traveling crossrail (Z-axis) and a rotary table providing multisided high-accuracy machining in a single-setup.
✓ Traveling crossrail (Z-axis) + a rotary table provide multisided 5-axis machining in a single-setup.
✓ The Finite Element Method provides increased rigidity.
✓ Additional turning operation extends technological capabilities of the machine.
✓ High rigidity roller-type linear guideways offer the advantage of both heavy-duty cutting and fast and smooth travel of the machine’s moving parts.
