Stresscraft Within St Winefrides Chapel

Centre hole drilling at Stresscraft is carried out on components and structures made from a wide variety of materials, including alloy steels, cast-iron, aluminium alloys, nickel super-alloys, titanium alloys, bearing steels, glasses and ceramics.  Residual stresses are usually measured to a depth of 0,5 mm, 1 mm or 2 mm, depending on the gauge size and drilled hole diameter.  All gauges are drilled using Stresscraft PC-controlled, 3-axis drilling machines with an orbital (circular milling) motion to cut the hole.  These machines, in conjunction with a range of straight, right-angle, reverse and offset drill heads provides access to measurement positions in `difficult' locations which would not be possible using conventional drilling machines.  The machines and drill heads are all manufactured ‘in-house’; adaptations to the range of drill heads and other equipment expand to suit the requirements of customers’ components and measurement positions.
