This comparison contrasts traditional rock-drill trimming with a Huada wire-saw trimming machine. The archived text focuses on stone damage, dust, labor and the condition of the finished cut rather than on machine specifications.
Rock-drill trimming
The source says traditional drilling can damage the stone, create comparatively more dust and require higher labor cost. It does not identify the drilling method, stone, crew or cost record used for that comparison.
Wire-saw trimming
Huada describes its trimming machine with dual frequency-converter control. The claimed result is efficient cutting and a flat surface without damage to the stone.
How to make the comparison useful
The choice is not simply “old tool versus new tool.” It depends on the value of the saleable block, the acceptable finish, available handling space and the work needed after trimming. Those project details are not recorded here. The defensible takeaway is that Huada positions controlled wire-saw cutting as an alternative where impact damage, dust and labor from rock-drill trimming are concerns. Any efficiency or cost advantage should be checked on the same stone and target shape.
