Horizontal Boring CNC Machining
The Horizontal Boring section comprises 1 Union machine, 3 Giddings & Lewis machines. An extensive range of tooling and ancillary equipment is available including, Multi Angled Milling Head, Facing & Contouring Heads, Out-Facing Bars and a Speed Multiplier to give a maximum spindle speed of 8,700 rpm. The machines cover an envelope of some 2.4 x 2.1 metres with a maximum table load of 10 tonnes. One machine is fitted with Renishaw Probing to enable accurate datuming of complex parts.

Seat Pocket Machining using Outfacing Bars
The drawings below illustrate a typical Tree Shape Oil Valve Body. There are four valves seat pockets @ 6.38” Dia and one @ 4.25” Dia with a total valve body length of 70”.
Stud type outfacing heads, bore valve seat pockets and piloted type outfacing heads are used to machine out the valve seat pockets.
A small stub type outfacing head is used to machine the smaller valve seat pocket.
