Top 10 CRT Cutting Machine Suppliers with Diamond Cutters in Japan

Founded in 1998 in Tokyo, NET has been a pioneer in e-waste recycling tech, and their CRT cutting line is a standout. Their flagship model, the CRT-Cut Pro 5000, pairs a diamond-tipped blade with a built-in ni-chrome heater array that pre-warms the glass seal to 60°C—just enough to soften adhesives without weakening the glass structure. What really sets them apart? The mechanism cutter system uses AI-driven cameras to scan each CRT's dimensions in real time, adjusting the cutting angle automatically. This means even old, misshapen CRTs from the 90s get clean cuts. A long-term client in Osaka's largest e-waste plant raves, "We process 200 CRTs daily, and the Pro 5000 hasn't needed blade replacement in 18 months—unheard of with our previous machines."

NET also offers full crt recycling equipment bundles, including glass separators and lead dust collectors, making them a one-stop shop for facilities scaling up their operations.

With a factory in Yokohama, TPCS has built a reputation for "Japanese precision at its finest." Their DiamondCut CRT Series 3000 is a favorite among small to mid-sized recyclers thanks to its compact design and user-friendly interface. Unlike bulkier models, it fits through standard doorways and can be operated by a single worker after just a day of training. The secret? A lightweight yet durable diamond blade (coated in industrial-grade diamond grit) and a simplified mechanism cutter that relies on manual alignment guides for smaller batches. "We wanted something that didn't require a robotics degree to use," says a manager at a Kyoto-based recycling co-op. "The Series 3000 lets our team focus on speed without sacrificing safety."

TPCS also offers a mobile version for on-site CRT processing, perfect for schools or offices upgrading to smart boards and needing to recycle old monitors on the spot.

OEMC has been around since 1975, and their longevity speaks to their adaptability. While they started with basic metal crushers, their CRT division now leads in energy-efficient cutting. The EcoBlade CRT-7000 uses 30% less electricity than competitors, thanks to a variable-speed motor and a ni-chrome heater that only activates during the cutting cycle. The diamond blade itself is a marvel: made from recycled industrial diamonds, it's designed to self-sharpen as it cuts, extending its lifespan to over 5,000 CRTs. "We're not just selling machines—we're selling sustainability," says OEMC's sales director. "Our clients love that the EcoBlade aligns with their carbon neutrality goals."

Another perk? OEMC provides 24/7 technical support, a lifesaver for facilities running night shifts to meet recycling quotas.

KRTI, a spin-off from Kyoto University's engineering department, is all about innovation. Their latest model, the SmartCut CRT-X, is the first to integrate IoT connectivity. Operators can monitor blade wear, heater temperature, and cutting speed via a tablet app, receiving alerts if the diamond blade dulls or the mechanism cutter misaligns. "We had a batch of 1990s Sony CRTs with uneven seals—usually a nightmare," recalls a tech at a Tokyo recycling plant. "The X-series scanned each one, adjusted the cutter path, and got through 30 units an hour without a single crack. It felt like having a robot co-worker."

KRTI also offers custom blade sizes for rare CRT models, like vintage arcade monitors or medical imaging displays—niche markets where precision is non-negotiable.

HPE's claim to fame? Heavy-duty durability. Their DiamondMax CRT-9000 is built for high-volume operations, handling up to 150 CRTs per hour with ease. The machine's frame is reinforced with steel, and the diamond blade is encased in a dust-tight chamber to prevent lead particle escape. A built-in ni-chrome heater with adjustable temperature settings (from 40°C to 80°C) ensures optimal cutting conditions, whether dealing with thick 21-inch TV funnels or thin 14-inch monitor panels. "We process over 10,000 CRTs a month, and the DiamondMax has been running non-stop for three years with only routine maintenance," says a plant manager in Hiroshima. "It's a workhorse."

HPE also offers on-site training for teams, covering blade replacement, heater calibration, and safety protocols—critical for keeping operations compliant with Japan's strict labor laws.

NEES prides itself on affordability without compromising quality. Their entry-level model, the CRT-Cutter Mini, targets small recyclers and community centers with tight budgets. At just $15,000, it's half the price of premium models but still features a genuine diamond blade and a basic mechanism cutter for manual alignment. "We wanted to make CRT recycling accessible to everyone, not just big corporations," explains NEES's founder. "The Mini might not have all the bells and whistles, but it cuts cleanly and safely—and that's what matters most."

Despite its size, the Mini is surprisingly robust: it can handle CRTs up to 27 inches and comes with a two-year warranty on parts. A community recycling group in Fukuoka calls it "a game-changer—we used to send CRTs to larger facilities, but now we process them locally, cutting transport emissions."

YMW's roots are in shipbuilding, so it's no surprise their CRT cutters are built like tanks. The MarineGrade CRT-8000 is corrosion-resistant, making it ideal for coastal recycling facilities where salt air can damage electronics. Its diamond blade is coated in a marine-grade polymer, and the ni-chrome heater is sealed to prevent moisture ingress. "We installed a MarineGrade in Okinawa five years ago, and it's still going strong despite the humidity," says a client. "YMW really thought of everything."

YMW also offers a unique "blade exchange program": instead of buying new blades, clients can send in dull ones for professional re-sharpening at a fraction of the cost—a hit with budget-conscious operators.

FGTI is all about modularity. Their CRT-Cut Modular System lets clients start with a basic cutter and add components—like a ni-chrome heater upgrade or an automated loading arm—as their business grows. "We work with a lot of startups that don't need a top-of-the-line machine on day one," says FGTI's product manager. "Our modular approach lets them scale without reinvesting in a whole new system."

The diamond blade is also modular: clients can swap between standard blades for most CRTs and specialty blades for extra-thick glass (like old projection TVs). A recycler in Sendai notes, "We started with just the cutter, then added the heater six months later when we got more CRTs. It was seamless."

SRS, based in Hokkaido, knows cold climates. Their ArcticBlade CRT-6000 is designed to operate in temperatures as low as -10°C, a must for recycling facilities without heated warehouses. The ni-chrome heater is beefed up to compensate for cold glass, and the diamond blade's lubrication system uses antifreeze to prevent freezing. "Winters here are brutal, but the ArcticBlade never skips a beat," says a Sapporo-based operator. "We've even used it in temporary outdoor setups during cleanup drives."

SRS also offers a "cold start" feature that pre-warms the machine in 10 minutes, so workers don't waste time waiting for it to heat up.

OEE rounds out our list with a focus on portability. The MiniCut CRT-2000 weighs just 200kg and fits in a standard van, making it perfect for island communities or remote areas without permanent recycling centers. Its diamond blade is small but mighty, cutting through 14-inch CRTs in under a minute, and it runs on standard 100V power—no special wiring needed. "We take it to villages all over Okinawa," says an OEE field technician. "People bring their old TVs, we cut them on-site, and the glass goes straight to a collection truck. It's recycling on wheels."

OEE also includes a built-in first-aid kit and safety training materials with each MiniCut—because even portable machines demand respect for safety protocols.
