자주 묻는 질문

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

A single-wire (다이아몬드 와이어 루프) 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.

Which is better for R&D or small-batch production?

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 (예), 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?

예. 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.
