Haas VF 2

The main parts of the Haas VF 2 vertical machining center are made of cast iron which eliminate vibrations from the operation. The frequency-controlled electric motor, which is capable of high acceleration and brake, drive the main spindle. The quick tool changer tray reduces non-productive times and increases machine productivity. 

The feedback control system optimizes the slip between the stator and the engine rotor and with the vector control doubles the torque at low revolutions. 

The machines are equipped with linear rolling lines in all axes. They provide high traction dynamics and accuracy of coordinate positioning with minimal friction. The ball screws are clamped at both ends to provide maximum parallelism. The temperature sensor on ball screw nuts changes the position of the ball screw. This makes the machining process consistently accurate. The spindle has the stable temperature thanks to flow coolant on the spindle block. The coolant is a cutting fluid which lowers down the machining area temperature and shows the machine temperature. 

The gearing is nitrided and then precisely ground. The highly precise layout ensures smooth operation even at high revolutions. Gearbox has an independent lubrication system with oil tank. The vibrations are eliminated by insulating layout with the polyurethane protrusions.
