Accutom-2
Instruction Manual
Having chosen the cut-off wheel, mounted the specimen, adjusted the
specimen holder, and levelled the stand, the cutting can now be started
according to the following steps:
Check that there is sufficient cooling agent in the recirculating cooling
unit (see section 7.7 for re-filling). If a recirculating cooling unit is not
mounted then check if the water supply is opened.
Adjust the stop screw (fig. 1.9) so that Accutom-2 stops when the
specimen has been cut through or the desired cutting depth has been
reached.
a) Turn on the Accutom by turning the SPEED knob (fig. 1.1) and let
the spindle rotate at low rate of revolution.
b) Push button FORWARD (fig. 1.5) and hold it until the cutting table
stops and the lamp TABLE STOP OR OVERLOAD (fig. 1.2) lights.
c) Hold the FORWARD button in and adjust the spacer screw to the
desired cutting depth.
d) Turn the SPEED knob back to OFF to re-couple the switch.
Adjust the placing of the cut by turning the micrometer screw.
This can be done most easily by moving in the cutting table so that the
specimen almost touches the cut-off wheel.
If necessary, a cut can be made so that a reference surface is then
obtained. If the cut is not all the way through there is furthermore the
possibility of measuring accurately the actual width of the cut.
Both lock screws (fig. 2.2 and 2.3) must be loose.
Lock the travel of the specimen holder in horizontal direction by: either
locking the micrometer screw (fig. 2.2) if rotating/swivelling cutting is
requested or locking the specimen holder tightly (fig. 2.3) if direct
cutting is requested.
Mount the protective screen of clear PVC.
Start the Accutom-2 by means of the SPEED knob (fig. 1.1) and set to
the requested speed.
Adjust flow of cooling agent (fig. 2.5) to requested quantity, usually
maximum.
Make sure that the discharge is not clogged.
Press the FORWARD button (fig. 1.5) to place the specimen closely in
front of the cut-off wheel.
Turn the FEED knob a little counter-clockwise (opens the valve) (fig.
1.4) and read out the pressure P

on the pressure gauge (fig. 1.6).
