How Does the CD-120NC Automatic Circular Saw Cutting Machine Tackle Ultra-Hard Metal Cutting?

2026-05-22

When it comes to cutting ultra-hard metals like tool steel, bearing steel, and alloy bars with diameters up to 120mm or square profiles up to 90mm, standard saws often struggle with precision, blade life, and efficiency. That’s where the CD-120NC automatic circular saw shines as a purpose-built solution.

Built for Durability: TCT Blades + Three-Point Clamping

The CD-120NC uses a Φ380×2.6mm TCT tungsten carbide circular saw blade, paired with a three-point clamping design. This drastically reduces blade vibration, extending blade life while ensuring consistent cutting accuracy, even under high loads.

Precision Feeding: Servo Motors + Ball Screw Transmission

The feeding mechanism adopts a swinging motion, coupled with AC servo motors and precision ball screw transmission. With a feed length range of 0–700mm (single stroke) or continuous operation up to 9999mm, the system delivers repeatable, precise feeding. The main clamp uses an upward pressure side clamp design to ensure firm, stable holding throughout cuts.

Clean, Eco-Friendly Operation

The saw blade uses oil mist cooling, which is clean, pollution-free, and better at lubricating the blade. It also features automatic separation of material heads, tails, and finished products, plus automatic discharge of iron filings. This keeps the workspace tidy and reduces downtime spent on cleanup.

Smart Protection + European-Designed Gearbox

The machine includes saw blade protection and overload protection devices to prevent costly damage. Its European-designed gearbox features a unique internal clearance design, paired with servo-driven ball screw feed, ensuring stable performance and long service life. The blade speed is adjustable from 20–150rpm, and the machine is powered by an 11KW (15HP) / 6P motor.

User-Friendly Touchscreen Control

The intuitive touchscreen interface makes operation simple, even for less experienced users. All parameters are clear at a glance, reducing setup time and operator error.

For fabricators tired of dealing with unreliable saws that can’t keep up with hard metal demands, the CD-120NC automatic circular saw offers a stable, efficient, and cost-effective solution.
