The Emag VTC 250 Twin is a used vertical turning machine, sometimes referred to as a vertical lathe or VTL, designed for precision turning operations on rotational components. Vertical turning machines of this type hold and rotate workpieces on a vertical axis, allowing gravity to assist in workholding and making them well suited to the machining of short, heavy, or disc-shaped parts. Emag is a well-established German manufacturer specialising in vertical pick-up turning centres and other precision metal-cutting equipment, serving industries such as automotive, commercial vehicle, and general engineering.
This particular machine was built in 2015 and is currently located in Germany. Its foundation is a MINERALIT polymer concrete base, a material widely used in precision machine tools for its superior vibration-damping characteristics compared to cast iron, which contributes to surface finish quality and long-term dimensional stability.
The machine is configured with two turrets, each carrying 11 tool stations, giving a total of 22 tool positions and considerable flexibility for multi-operation or simultaneous machining cycles. Tool shanks are sized at 40 mm in diameter. The spindle nose conforms to DIN 55026-A6, and the front bearing diameter is 110 mm. Maximum spindle speed is 5,000 rpm, while the main drive delivers 29 kW and 200 Nm of torque at a nominal power speed of 1,400 rpm, rated at 100% continuous duty cycle.
Workpiece capacity covers diameters up to 140 mm and lengths up to 630 mm, with a maximum workpiece weight of 20 kg. Axis motion is handled by ball screws measuring 32 mm in diameter on the X-axis and 40 mm on the Z-axis. Rapid traverse rates are 30 m/min in X and 40 m/min in Z, while feed forces reach 9.4 kN in X and 10 kN in Z, indicating a machine capable of robust, productive cutting passes.
A key feature of this machine is its integrated Emag pick-up system, which allows the spindle to collect raw parts directly from a conveyor or parts carrier and return finished parts autonomously, eliminating a separate loading device. This automation is reflected in the published cycle data: loading time is quoted at 4 to 5 seconds and chip-to-chip time at 6 to 7 seconds, figures consistent with high-volume production environments where minimising non-cutting time is critical. The machine operates on two axes and is classified as a vertical turning machine.
