It is made of the single-piece casting of Semi-steel ( Chilled Cast Iron). The bed consists of two heavy metal slides running lengthwise, with ways or 'V' formed upon them and rigidly supported with cross girths. It is sufficiently rigid and good damping capacity to absorb vibration. It prevents the deflection produced by the cutting forces.
