4. Description of the LEICA EM KMR2
The scoring and breaking mechanism for knife making are assembled on a heavy,
vibration-absorbing base.
The parts are shown in Fig.9:
1. Clamping lever:
is used to lower and raise the scoring head and also to clamp the
scoring head to the clamping head (No.2). For user-preferred positioning the lever can
be adjusted by pulling it horizontally to the left, rotating it and pushing it back.
The best position is horizontal when clamped with glass in place.This way the same
scoring pressure can always be applied during the knife breaking process.
2. Clamping head:
carries the scoring head and the clamping lever.
3. Scoring head:
carries all necessary elements for scoring and breaking the glass.
The scoring head is lowered into position by means of the clamping lever (No.1).
4. Breaking lever:
is used to break the glass after scoring. By turning the lever slowly
clockwise a pin moves against the glass to break it. This lever can be positioned by the
user by pulling it vertically upwards, rotating it and pushing it back.
5. Ruler:
acts generally as a stop for the glass strip. The glass strip is pressed against the
ruler before it is clamped. The left hand ruler acts also as a track for the moveable stop with
its four click stop positions.
6. Scoring mark selector:
can be set by rotating to two different scoring lengths.
The long score (22 mm) is for scoring the glass strips to break squares for making routine
knives for resin sectioning.
The short score (12 mm) is used to score squares for making high quality knives for cryo
sectioning.
When the long score is used for making knives the quality of the knife is high and also
more reproduceable.
7. Scoring shaft:
is pulled out with reasonable speed to the endstop to score the glass
before breaking.
8. Moveable stop
with its four cklick positions is mounted on the left hand ruler and is
used to break the 400 mm long glass strips according the balanced break method.
9. Rotatable knob:
is used to move the rear stop (No.11) forwards to locate the glass
strips and squares against the ruler.
10. Front stop:
is to hold and position squares during scoring and breaking of knives.
11. Rear stop:
is used to hold and position the glass strips and the squares against the
front stop (No.10) when breaking knives from the square.
