4) Manual for the use of the diamond wire in quarry
Definition of different cutting patterns - Stitch drilling, deep hole drilling,
vertical through-cutting, vertical cutting with flam-jet preparation, vertical
bench cutting, horizontal cutting.
Preparation of holes - Tracing and drilling of horizontal hole, tracing and
drilling of vertical hole, possible hole repetition.
Positioning machines and equipment - Positioning of guide pulleys,
positioning of rails, positioning the machine on the rails, alignment of the
Mounting the diamond wire - Cleaning of work area on bench top,
determination of wire lenght to be used, checking state of wear of wire,
insertion of the wire into the holes, prewinding of wire, joining the wire,
positioning of wire on drive and guide pulleys, cooling plant setup.
Start of cutting - Slight pre-tensioning of wire, running the wire by hand,
checking of wire rotation, starting the machine in manual position, rounding
of edges, intermediate stops during cutting, movement and elimination of
the rear guide pulley, Modifying water jet position.
Continuation of cutting - Change to automatic working of machine, checking
and periodic substitution of the join, checking and repositioning of the
cooling plant, checking state of wire wear and state of advancement of cut,
insertion of bars in the cut.
Exit from cut - Wire substitution, start-up of final stage of cutting, exit from
cut, recovery and care of the wires used and the equipment.
Tipping and sectioning the bench - Detachment of bench, separation of
bench by hydro-bag, tipping the bench with hydraulic jacks.
Addendum: Use of diamond wire for stationary machines - Preliminaries,
start of process-cutting, continuation of cutting, trouble shooting.
