Producing a pyramid or a sloping face
Swivel the specimen pivot arm using lever (3) to the desired pyramid angle between
30° and 45° (recommended for producing a pyramid)
Rotate the specimen using the knurled ring (9.3) until the first click stop position.
Make sure that the 90° click stop position is correctly engaged.
The milling operation for producing the pyramid sides are the same as described for
the cutting face.
By swivelling the specimen pivot arm the specimen moves closer to the miller
and might interfere with the miller. Before you start milling make sure the miller
will not cut the sample with an uncontrolled advance. We recommend to retract
the miller by turning the feed hand wheel clockwise or with the HOME button of
the control panel.
While observing in the stereo microscope move the milling control lever (7) slowly
down. If no material is removed rotate the feed hand wheel counter clockwise
(advancing the miller towards the specimen).
One click stop of the feed hand wheel (2) corresponds to the selected step size to
advance the miller.
After the first pyramid face is produced, retract the miller and rotate the specimen
using the knurled ring (9.3) to the next click stop position and proceed as described
above until all four sides of the pyramid are produced.
It is not necessary to trim the cutting face with the 90° click stop position of
ring (9.3), although we recommend this. The specimen may be rotated any
amount so that trapezoids or any other shapes can be produced.
