Boring Head

How does a boring head work?

 

 

An offset boring head is used for the purpose of boring accurate holes with close diametrical tolerances. The body comprises of two units attached together by means of a sliding dovetail joint. A dial screw with fine graduations of uniform increments is fixed between the two units. The rotary motion of the screw is converted to a precise translatory motion of the upper unit as it slides over the lower body. The boring tool can be mounted onto one of the three holes (two on the top edge and one on the side of the upper unit) clamped firmly in place by means of the grub screws. The head can be mounted onto a number of screw-threaded shanks having varied tapers matching various machine spindles.
