Abstract
A lathe comprises at least one base unit which is constructed from two machine beds 4, 7. The machine beds are cast as a one-piece unit from reaction resin concrete and carry the bed guides 5, 8 for a spindle box 6 which is displaceable in the direction of the spindle axis 10 and a tool carrier slide 9 with a tool turret 3. The bed guides are at a right angle relative to one another. Each spindle box comprises a projection 15 which has the length of the displacement path of the spindle box 6 and penetrates through a dividing wall 16 at the front end of the displacement path which is arranged at a right angle to the spindle axis 10. The switching axis 11 of the tool turret 3 is arranged at an angle relative to the longitudinal direction of its bed guide 8. In the construction of a lathe with two spindles the machine beds 4 of the spindle boxes 6 are glued together over a large surface area and the machine beds 7 for the tool carrier slides 9 are arranged at a right angle relative to the latter in a mirror-inverted manner at the machine beds 4.
