6.4 Feed specimen into cutting wheel by operating handle at front of machine. When
cutting on angled or irregular surfaces feed very slowly until cutting wheel is fully
entered into specimen. Fast feeding at the start of cut causes the cutting wheel to
deflect from a true cutting path and thus produces a cut face which is not flat.
6.5 To produce further cuts, move specimen forward in the vice the desired amount and
repeat cut.
6.6 Diamond wheels must not be used without coolant. Abrasive wheels can be used dry
but this usually results in heavy wear.
7 Cutting Cores for Compression Test
7.1 Clamp the core in the vee blocks, first setting the centre block at suitable spacing to
support the core inside the desired cut length. The left hand vee should not be moved.
The right hand vee block is to support the cut off piece of core in cases where the core
is much longer than the desired cut length.
7.2 Set the slide at the zero line which is 1.5 mm (
1
/
16
inch) to the left of the rule zero. This
allows for wheel thickness. Lock slide with lock screw on front of slide.
7.3 After making sure the core is firmly clamped, cut through at the zero reading, return
slide to position where the cutting disc is clear of the vee blocks and clamps. Move
slide to the left until you read off the length on the rule and repeat cut.
7.4 The start of all cuts should be done carefully to avoid wheel deflection, which can
produce a cut out of square.
8 Cutting Cubes
8.1 These can be produced from 25 mm (1 inch) to 50 mm (2 inches) dimension. First cut
a slice from the core to desired dimension as cutting instruction on previous page, thus
producing two parallel faces. Lay the slice in the left hand vee block with one parallel
face on the rear vee face clamp and cut two more faces on the same readings as first
two cuts, producing a square prism with radius end faces. Lay the prism in the vee
block with radius ends protruding either side and repeat cuts to produce cube.
9 Maintenance
9.1 Coolant tank and pipes should be cleaned out and disinfected regularly, excessive
sludge accumulation can result in water pipes becoming clogged and water supply
failing during cutting. This may result in diamond wheel damage. To clear water pipes
first clean machine, tray and tank and fill with fresh coolant. Next remove screws which
seal the ends of the water pipes and flush through. If the small jet holes in water pipes
are clogged, clear with small piece of wire. Replace screws and check all jets are
working.
10 Lubrication
– Spindle
10.1 The spindle is grease lubricated and should be greased once a month. Be careful to
replace grease nipple caps to prevent abrasive dust entering bearings. Recommended
Grease
– Total Multis EP2 or similar.
