TDG NISSIN's NWSS-250 and NWSS-250A are diamond-wire croppers that take the head and tail off 25 polycrystalline blocks in one load. One data sheet lists both: 156 × 156 × 300 mm stock, 0.31–0.33 mm coated wire, 900 m/min. The 250A has a shorter 350 mm lift, draws 35 kW against 27 kW and needs more floor space. The product page text says 400 mm blocks, so settle block length when you ask for a quote.

The NWSS-125G is the smaller G5 diamond-wire squarer in the TDG NISSIN range. It squares 25 mono ingots of 6 or 6.5 inch or 16 of 8 or 8.5 inch, or cuts an 840 × 840 × 500 mm poly block into 25 columns. Wire speed reaches 720 m/min, power is 85 kW and the frame is 3550 mm long.

NWSS-125H is the TDG NISSIN G6 squarer for fixed-abrasive diamond wire. Its mono fixtures carry 36 ingots at 6 or 6.5 inch, or 25 at 8 or 8.5 inch, or cuts a 1000 × 1000 × 500 mm poly block into 36 columns of 156 × 156 × 500 mm. Coated wire of 0.31–0.33 mm runs at up to 900 m/min, and the machine is rated 90 kW.

The NVG-7500 is a TDG NISSIN vertical centre that grinds the flat faces and rounds or chamfers the corners of mono ingots and poly blocks after squaring. It takes 156–160 mm sides or 8–10 inch diameters, spins wheels up to 3000 rpm and draws 45 kW. Ask which model revision and length limit the quotation covers.

TDG NISSIN's NWSS-125M(K) squares a G6 load with slurry-assisted multiwire cutting. One fixture takes 36 mono ingots of 6 or 6.5 inch, another takes 25 of 8 or 8.5 inch, and a poly setup turns a 1000 × 1000 × 450 mm block into 36 pieces measuring 156 × 156 × 450 mm. Listed machine power is 100 kW.

The NWSS-JK4700 crops and squares monocrystalline silicon on one machine, and TDG NISSIN says both jobs can run at the same time. It takes one 4 m ingot of 8–9 inch diameter and works segments 150–700 mm long. It suits plants that want to merge two ingot steps into one footprint. Ask for a timing chart and material-route drawing with the quote.

The NWSS-DD700Z squares one monocrystalline ingot segment at a time with diamond wire. TDG NISSIN lists 150–700 mm segments in 200–250 mm diameter. Loading and unloading grippers come with the machine; edge detection and automatic centring are options. It suits smaller squaring cells. Specify your square drawing and which options you want when asking for a price.

The NWSS-210 crops three monocrystalline ingots at the same time using diamond multiwire across six cutting heads. TDG NISSIN lists 2.2 m ingots in 6, 6.5, 8 or 8.5 inch diameters and a thin 0.31–0.33 mm coated wire. It fits plants that cut full-length ingots into segments in one pass. Send your cut map for each ingot when you ask for a quote, and check the 400 L/min cooling demand.

The NWSS-6S is TDG NISSIN's six-block cropper for polycrystalline silicon. It trims the head and tail of six 156 × 156 mm blocks with diamond multiwire, taking 220–400 mm incoming blocks down to 160–330 mm. Two rotating tables let the next batch be loaded while the current one cuts. It suits plants running shorter blocks than the seven-block NWSS-7S handles. Quote it with your block drawing and the finished length you need.

The TDG NISSIN NWSS-DH02 is a compact single-wire diamond machine for cropping monocrystalline ingots and cutting sample slices, with finished lengths of 100–700 mm, 12 kW power and a 2000 kg frame. Its text gives 8–12 inch stock over four metres long, while its table gives one 6–8.5 inch, four-metre ingot, so settle the size range first.

The TDG NISSIN NWSS-DS700Z squares two monocrystalline ingot segments per cut with diamond wire. It takes 200–250 mm diameter segments 150–900 mm long, centres them with mechanical grippers, finds the crystal edge with a measuring instrument and removes side pieces automatically. Power is 37 kW. Your drawing sets the final square size and tolerance.

The TDG NISSIN NWSS-7S is a diamond multiwire cropper that cuts heads and tails off seven 156 × 156 mm polycrystalline blocks in one pass, taking 270–450 mm incoming lengths down to 230–400 mm. It draws 39 kW at 380 V and weighs 11000 kg. Its English sheet heading says single end, so have the quotation state double-end cutting.
