The comparison for Diamond wire cutting and Slurry cutting

Item

Diamond Wire Cutting

Slurry Cutting

Cutting wire

The steel wire of surface coated with diamond

Smooth surface of steel wire or structure line

Silicon carbide

NA

New Silicon Carbide + Recovery Silicon Carbide

Cutting fluid

Aqueous coolant

PEG, DEG as the main component

Cutting efficiency

Fast cutting speed 1.4-2.0mm/min

Slow speed 0.4-0.5mm/min

Slurry configuration

NA

needs to fully mix the slurry

Auxiliary material recovery

Aqueous coolant, only need to filter out powder

Need complex equipment to recover silicon carbide and cutting fluid

Silicon wafer cleaning

Simple cleaning, high cleanliness

Silicon carbide, coolant, metal ions on the surface
