The lathe that the utility model embodiment provides comprises: main spindle box, change gear box, feed box, slip crate, knife rest, tailstock, feed rod, leading screw, lathe bed, cabinet base and cooling device; Said lathe bed is the triangular prism structure; Its cross section is an isosceles triangle; Its bottom surface (1) is a work top, and two sides (2) are supporting surface; Evenly be provided with first through hole (21) on two sides (2).

Wherein, said lathe bed inside is provided with a reinforcement (3); Said reinforcement (3) is vertical with bottom surface (1), the central lines of one of which side and bottom surface (1), and another side overlaps with the connecting line of two sides (2); Evenly be provided with second through hole (31) on the said reinforcement (3).

Wherein, said lathe bed inside evenly is provided with reinforcement face (4) in the direction perpendicular to the lathe bed axis; Said reinforcement face (4) is a triangle, and its shape is identical with said lathe bed cross section, and three limits of reinforcement face (4) are fixing with bottom surface (1) and two sides (2) welding of lathe bed respectively.

Wherein, each reinforcement face (4) is provided with two third through-holes (41), and said third through-hole (41) is positioned at the both sides of said reinforcement (3).

Wherein, respectively be provided with three first through holes (21) on two sides (2); Reinforcement (3) is provided with three second through holes (31).

The utility model embodiment provides a kind of lathe, has changed traditional body of lathe bed structure, and lathe bed is the triangular prism structure; And on side and inner reinforcement and reinforcement face, be provided with through hole; Improve the intensity of lathe bed greatly, prolonged the service life of lathe bed, guaranteed the precision of lathe; Go back economical with materials simultaneously, reduce cost.
