I have over 15 years experience in the wafer slicing wire saw industry, and I have seen how the improper coolant can damage a whole batch.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this article we will explore what coolant to use, why DI water and cutting fluid matter, and how pH control makes your operation safe and clean.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What Is a Wafer Slicing Wire Saw and How Does It Work?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A <strong><a href=\"https:\/\/www.semiconductorcutting.com\/ko\/%ec%a0%9c%ed%92%88-%ec%b9%b4%ed%85%8c%ea%b3%a0%eb%a6%ac\/%ec%a0%9c%ed%92%88-2\/multi-wire-saw-machines\/\" target=\"_blank\" rel=\"noreferrer noopener\">wafer slicing wire saw <\/a><\/strong>is a kind of cutting machine. It cuts hard materials like silicon, SiC and sapphire into thin wafers. It employs a thin diamond-coated wire. The wire zips swiftly across the fabric. Groove wheels to keep the wire on the track. This means minimal kerf loss \u2013 very little material is lost.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To slice the silicon wafer you need both speed and precision. Coolant is sprayed onto the cutting zone. It cools the wire and eliminates chopped pieces. Without cooling, wire and wafer might become too hot. This leads to cracks and damages.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"800\" height=\"800\" src=\"https:\/\/www.semiconductorcutting.com\/wp-content\/uploads\/2026\/06\/image-4.png\" alt=\"\uc6e8\uc774\ud37c \uc2ac\ub77c\uc774\uc2f1 \uc640\uc774\uc5b4\ud1b1\" class=\"wp-image-5539\" style=\"width:460px\" srcset=\"https:\/\/www.semiconductorcutting.com\/wp-content\/uploads\/2026\/06\/image-4.png 800w, https:\/\/www.semiconductorcutting.com\/wp-content\/uploads\/2026\/06\/image-4-300x300.png 300w, https:\/\/www.semiconductorcutting.com\/wp-content\/uploads\/2026\/06\/image-4-150x150.png 150w, https:\/\/www.semiconductorcutting.com\/wp-content\/uploads\/2026\/06\/image-4-768x768.png 768w, https:\/\/www.semiconductorcutting.com\/wp-content\/uploads\/2026\/06\/image-4-12x12.png 12w, https:\/\/www.semiconductorcutting.com\/wp-content\/uploads\/2026\/06\/image-4-600x600.png 600w, https:\/\/www.semiconductorcutting.com\/wp-content\/uploads\/2026\/06\/image-4-100x100.png 100w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Technical Overview: Wafer Slicing Wire Saw Key Parameters<\/strong><\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>\ub9e4\uac1c\ubcc0\uc218<\/strong><\/td><td><strong>\uc138\ubd80 \uc815\ubcf4<\/strong><\/td><\/tr><tr><td>\uc640\uc774\uc5b4 \uc720\ud615<\/td><td>Diamond-coated steel wire<\/td><\/tr><tr><td>\uc640\uc774\uc5b4 \uc18d\ub3c4<\/td><td>10\u201330 m\/s<\/td><\/tr><tr><td>\ub0c9\uac01\uc218 \uc720\ud615<\/td><td>DI water \/ cutting fluid<\/td><\/tr><tr><td>Material Cut<\/td><td>Silicon, SiC, Sapphire<\/td><\/tr><tr><td>Kerf Loss<\/td><td>100\u2013200 \u00b5m<\/td><\/tr><tr><td>\ud45c\uba74 \ub9c8\uac10<\/td><td>Ra &lt; 1 \u00b5m<\/td><\/tr><tr><td>Groove Wheel Role<\/td><td>Wire tension and path control<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Why Does Coolant Choice Matter in a High Speed Multi Wire Saw Machine?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Using the improper coolant poses major complications. It may snap a wire. It may harm the wafer surface. It might reduce your yield. In a <strong><a href=\"https:\/\/www.semiconductorcutting.com\/ko\/how-do-multi-wire-saw-machines-work\/\" target=\"_blank\" rel=\"noreferrer noopener\">high speed multi wire saw machine<\/a><\/strong> coolant does more than just cool. It cleans away debris. It reduces drag. If the coolant is excessively acid or alkaline, it will eat the wire.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It might also fracture the wafer from behind. That\u2019s why we need to adjust the kind of coolant and pH. This is a must for all precision wire saw cutting systems. It is the secret to high precision wafer slicing and longer machine life.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What Is DI Water and Why Is It Used?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">DI water stands for de-ionized water. It contains very few minerals. It is the primary coolant for most wafer slicing wire saw systems. It does not deposit on the wire, nor on the wafer.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>DI water has an extremely low conductivity. Protects the wafer surface.<\/li>\n\n\n\n<li>It cleans the cutting area. No Pollution.<\/li>\n\n\n\n<li>And it can easily be filtered and reused in a closed-loop system.<\/li>\n\n\n\n<li>It is compatible with cutting fluid additives.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>DI Water Properties in Wire Saw Cooling<\/strong><\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>\uc18d\uc131<\/strong><\/td><td><strong>Value \/ Description<\/strong><\/td><\/tr><tr><td>Conductivity<\/td><td>&lt; 1 \u00b5S\/cm<\/td><\/tr><tr><td>pH Range<\/td><td>6.5 \u2013 7.5 (neutral)<\/td><\/tr><tr><td>Particle Filtration<\/td><td>0.2 \u2013 1 \u00b5m filter size<\/td><\/tr><tr><td>Recycling Rate<\/td><td>Up to 90% in closed systems<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How Does Cutting Fluid Help in the Silicon Wafer Slicing Wire Saw Process?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Cutting fluid mixed with DI water. It enhances lubrication and cooling. It reduces the heat at the wire-wafer contact point. It also helps to remove small chopped particles.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>It reduces the surface tension. The coolant is distributed more evenly.<\/li>\n\n\n\n<li>Protects the wire coating on extended cuts.<\/li>\n\n\n\n<li>It decreases the danger of small subsurface damage cutting.<\/li>\n\n\n\n<li>It is useful to maintain the groove wheel wire control steady.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How Does pH Control Protect Your SiC Wafer Cutting Equipment?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">pH regulation is commonly forgotten. But that is really crucial.\u00a0 \u201cIf the pH gets too high or too low, bad things will happen.\u201d It may etch on the wafer surface. It may eat through the wire covering. pH changes induce pitting in SiC wafer cutting equipment, sapphire wafer slicing machine configurations. They also result in loss of flatness.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ub54c\ub54c\ub85c \ubc30\uc120\uc774 \uace0\uc7a5\ub0a9\ub2c8\ub2e4. pH\ub97c 8\uc5d0\uc11c 9.5 \uc0ac\uc774\ub85c
