What Is a Multi Wire Saw Machine?<\/h2>\n

\"What<\/p>\n

Multi wire saw is a cutting equipment for slicing a work piece into innumerable pieces in one step, by making use of multiple parallel wires at the specific intervals, generating flat and even wafers or slabs.<\/p>\n

In contrast to a single wire saw tool that takes one cut at a time, multi wire saw machine achieves several hundred or even thousands of cuts simultaneously. Wire guide roller with machined grooves establishes the wire pitch that governs the slice thickness. Workpieces are fed into the wire web at a controlled rate.<\/p>\n

Between that, there are two separate sorts of wire for the two main families of multi-wires saws:Free abrasive, slurry-based: bare steel wire. Cutting happens through the slurry of silicon carbide grit suspended in PEG (Polyethylene glycol); andFi\u00d7ed abrasive, diamond wire: granite is in the fi\u00d7ed grit (although it is actually tiny, Synthetic diamond particles) bonded directly to the wire, which is responsible for the cutting.<\/p>\n

Both the types of blade have their own unique benefits, depending on the material being cut, level of precision needed and the volume of production. Other types of blade can be found outside of these two main categories, such as specialized options for stone block cutting, and endless loop machines for materials requiring more extreme cutting techniques. Below we break down each of the types of blade available by their mechanism of function, specifications and the industry that uses them – helping designers and buyers alike visualize which machine is suitable for the application.<\/p>\n

Slurry-Based Multi Wire Saws<\/h2>\n

\"Slurry-Based<\/p>\n

Slurry-based multi wire saws (also known as free abrasive wire saws) were the first workhorse machines of the silicon wafer industry. These machines employ bare steel wire (generally 100-160 m diameter) that is wound around guide rollers to create a wire web. Wire itself does not perform any cutting, but it instead allows a flow of slurry containing SiC abrasive particles in polyetherketone (PEG) onto the wire web.<\/p>\n

As the wire travels at a high speed, it drags the abrasive particles across the workpiece surface. Abrasive particles do then the actual work of the material removal process using a three-body abrasion process.<\/p>\n

Historically, slurry based- systems have been the market leader for solar cell and semiconductor wafer production. Production machine wire counts are between 1,000 to 2,000+ per machine and a single 300 mm silicon ingot can be cut into hundreds of wafers in a single run. Welds occur at a relatively low wire tension (about 20-30N per strand) and wafers possess what can be described as a “matte” appearance.<\/p>\n

However, the kerf width of slurry-based saws is generally in the region of 200-250 m – substantially wider than a diamon wire substitute. This is important because each wafer therefor produces a larger amount of sawdust from the original raw material. Blanch et al. from the International Journal of Advanced Manufacturing Technology found that when silicon ingots are sawn into 200+ m wafer, 40-50 % of the original silicon ingot becomes sawdust.<\/p>\n

Slurry composition \u2013 most monocrystalline silicon sapphires use SiC #800-#1500 suspended in PEG. Wire tension-20-30N\/strand. Kerf loss (200-250 m) translates into roughly 40-50% waste of silicon ingots which becomes a main reason for the industry switching to diamond wire. The slurry should also be constantly recycled and re-supplied which makes process control and environmental requirements even more challenging.<\/p>\n<\/div>\n

As of today, slurry based multi wire saws are almost completely replaced by diamond wire systems in monocrystalline silicon manufacturing. they are, however, still used in some multicrystalline silicon applications and for sawing materials where the softer three body abrasion with loose abrasive in slurry causes less damage in the subsurface then direct diamond impact. The grinding\/lapping action of loose abrasive may generate lower cracks depths in some brittle materials and this can be beneficial for subsequent wafer thinning and polishing.<\/p>\n

<\/p>\n

Diamond Wire Multi Wire Saws<\/h2>\n

Although single wire cutting is still used in some industries, diamond wire multi wire sawing is the current industry standard in semiconductor and photovoltaic industry. Different from using loose abrasive in slurry, the solid abrasive that is attached to the wire is diamond particles, either through electroplating (nickel-bonded) or through resin bonding. With this long two body impact (abrasive to work piece), the cut efficiency as well as the material waste is greatly improved comparing to slurry based. Figure illustrates how the solid abrasive wire is made. Each wire is designed to directly impact into the work piece.<\/p>\n

Market numbers are quite clear. According to Statista, more than 98% of the wafer manufacturing market share of mono crystalline silicon is now served by wire sawing technology. Global diamond wire sawing market size is valued at $1.08 billion in 2024 and expected to reach a value of $2.14 billion by 2033 with a CAGR of 8.5% owing to the rising photovoltaic cell market as well as increase in demand for silicon carbide substrates for power electronics in electric vehicles.<\/p>\n

Wire diameter is an important parameter. Present demarcated maximum core wire diameter is at 36 m, while the effective core diameter including diamond overlay is around 50-60 m, a combination that results in around 55-80 m of kerf width, which according to the newly published PCME data, saves approximately 30 % of the cutting raw material mass (Procedia Manufacturing). 3. Conventional semiconductor wire diameters are generally larger with 100-350 m, which results in kerf widths of 150-350 m [PMC 184 (198), 201]. Savings are proportionately proportionate.

Sub-Types: Electroplated vs. Resin-Bonded<\/h3>\n

Electroplated diamond wire: diamond particles are electroplated onto a nickel plated steel core wire. This type of wire is more aggressive and faster since the diamond particles are more exposed. Electroplated wire is widely used in semiconductor industry where a fast cut with uniform kerf is desired. Resin-bonded diamond wire: the diamond particles are bonded in a resin matrix. It may contain one or more layer of diamond coatings. Resin bonded wire provide a slower but much longer wire life. It has seen wider use in stone processing industries.<\/p>\n

Uses of diamond wire multi wire saws include silicon wafer slicing, SiC substrate slicing, sapphire window cutting, quartz processing and compound semiconductor wafer slicing. More progress is being made as UV assisted diamond wire cutting and sawing was proven to effectively reduce surface roughness by 4.3-29.7% in varying granularities of Kaolin compared to conventional DWS, with the joint publication provided by National Institute of Health (NIH) and Pacific Northwest National Laboratory (PNNL) in Micromachines (2023).<\/p>\n
