Часто задаваемые вопросы

What is the difference between single-wire and multi-wire diamond cutting?

A single-wire (Петля из алмазной проволоки) machine drives one closed loop of diamond-coated wire to cut one kerf at a time. A multi-wire saw guides dozens of parallel wire strands so many slices are cut in one pass.

Single-wire diamond loop machines: they cost far less, change over quickly between materials, and can do contour cutting that multi-wire saws cannot.

When does a multi-wire saw make more sense?

In high-volume standardized wafer production (например., photovoltaic silicon bricks), where dozens of identical slices per pass justify the higher machine cost and setup complexity.

Can a diamond wire loop do contour cutting?

да. CNC-controlled single-wire loop machines cut curves and irregular shapes, which is a key advantage over multi-wire saws limited to straight parallel slicing.
