Table Type Horizontal Boring and Milling Machine

Conventional/NC controlled Horizontal Boring and Milling Machine

The headstcck has three concentric spindles. The outer sindle is hollow. At its front end its fitted the facing head. It runs in a taper bore bronze bearing. The correspondence portion of the spindle has a matching taper. The running radial clearance is obtained by axial adjustment cf the spindle. Inside this hollow spindle is a sleeve mounted on class P5 machine tool double rowm roller bearing. The bering spindle passes through this sleeve. The drive to the o#boring spindle is through akey fitted in the sleeve, which engages with a keyway along the entire length of the boring spindle to rotate and also travel Axially in the sleeve.
