The historical article separates diamond wire sawing into a press or pressing-cable method and a ring or lasso method. Its useful distinction is the rope geometry and stated application boundary, not a step-by-step setup procedure.
Press or pressing-cable method
In the archived description, a drilling rig or a cutting-column sheave presses the rope in the hole. The source limits this method to working-face cutting, describes it as vertical cutting, and excludes shaping after the stone has been segmented.
These statements describe how this page distinguishes the method. They do not provide rope-routing dimensions, tension, drilling tolerances, guarding or a machine-specific sequence. Treat the geometry and application limit as taxonomy that still requires the applicable equipment instructions.
Ring or lasso method
The second method uses a closed beaded rope surrounding the rock. The source says the contact curve changes as cutting progresses. Within its own classification, ring sawing can be used for both working-face cuts and shaping cuts.
The old text permits vertical and horizontal orientations for this method. It also mentions two relative machine-level directions for vertical cuts, but it does not turn that distinction into a complete setup. The machine position and rope route therefore remain matters for the current documentation.
Keep the terminology uncertainty attached to the comparison
The introduction of the archived page calls the first method “down sawing,” while its body uses press or pressing-cable terminology. The source does not establish that those labels are confirmed synonyms. This rewrite uses the body terminology and preserves the inconsistency as an evidence limit.
The comparison should also remain source-bounded. It is not presented as a universal industry standard, and the shared saved video cannot by itself establish either method. Use the page to distinguish the two archived geometries, then verify the chosen arrangement for the actual machine and cutting task.
