TTB series Slant Bed CNC Lathe The 45 degree slant bed is one-piece manufactured from high quality Meehanite cast iron, tempered and stress relieved. This results in maximum stability of structural material and deformation-free performance for years. The structure is analyzed by 3D Finite Element Analysis to achieve superior rigidity of structure, while reducing structure deformation to a minimum. Extra wide box ways on X, Z-axis. The box way surfaces are hardened, precision ground, then coated with Turate-B. These box ways provide outstanding wear resistance and make the machine ideal for heavy cutting.
