The KEENSAW KCS-90B is a heavy-duty, high-efficiency CNC circular cold saw designed specifically for mass-production cutoff of solid metal bars, thick-walled pipes, and structural profiles up to φ90mm in diameter. Powered by precision AC servo drives and a high-torque helical gearbox, the KCS-90B combines extreme cutting speed with exceptional linear repeatability, reaching positioning accuracy within ±0.05mm while delivering clean, mirror-like, burr-free surfaces that eliminate secondary grinding operations completely.
Engineered for maximum operational ROI, the KCS-90B seamlessly handles tough materials—including carbon steel, stainless steel, alloy steel, and titanium—in a fully automatic 24/7 environment. With its intelligent PLC touch-screen system and integrated automatic magazine loader, a single operator can effortlessly manage up to 4 sets of KCS-90B machines simultaneously, dramatically lowering factory overhead.
KCS-90B CNC circular saw cutting machine is equipped with 2-Axis servo driving material feeding and cutting feed, suitable for mild steel, stainless steel, alloy steel, hard steel…
Feed Mode: Horizontal Push Type
Cutting Capacity: Ø20-90 mm
Saw Blade Diameter: Ø315mm
Understanding the consumable cost per cut is critical for production managers. The benchmark data below demonstrates the economic efficiency of running a standard TCT saw blade on the KCS-90B processing φ50mm mild steel solid bar stock:
| Stage / Metric | Cutting Area Yield | Total Cut-Off Pieces (φ50mm) | Estimated Cost Per Cut |
|---|---|---|---|
| Original Blade (1st Cycle) | ~35 m² | ~17,850 Pieces | ~$0.0056 USD / cut |
| After 2 Professional Resharpenings | 70 m² – 84 m² Total | 35,700 – 42,840 Total Pieces | Less than $0.003 USD / cut |
*Note: Calculated using standard φ285*60T TCT saw blades priced at approx. $100 USD/piece. Actual yield varies based on material hardness, blade feed rate, and coolant efficiency.

Q1: What is the maximum cutting capacity of the KEENSAW KCS-90B?
A: The KCS-90B is optimized for high-speed cutting of solid round bars, square stock, and thick-walled pipes up to φ90mm in diameter across carbon steel, stainless steel, titanium, and nickel alloys.
Q2: What is the cutting speed and shift production output of the KCS-90B?
A: Taking φ50mm mild steel solid bar (20mm cutoff length) as an example, actual cutting time takes only 3.7 seconds, with a total cycle time of 4.8 seconds. This enables a single KCS-90B machine to output approximately 6,000 finished pieces per 8-hour shift.
Q3: Does the KCS-90B require manual material loading?
A: No. The standard KCS-90B configuration comes equipped with a fully automated incline magazine loading rack, auto-feeding shuttle vise, automatic cutting cycle, and automatic remnant separation.
Q4: What blade size does the KCS-90B use and what is its resharpening potential?
A: The KCS-90B utilizes high-performance TCT carbide saw blades (typically φ285*60T). A single new blade yields ~17,850 cuts on φ50mm steel bar and can be resharpened up to 2 times, achieving a cumulative lifespan of 35,700 to 42,840 cuts.
Q5: What warranty and spare parts package comes with the KCS-90B?
A: Every KCS-90B purchase includes a 12-month warranty, lifetime technical consultation, 24-hour rapid technical support, and 1 complimentary spare parts package sufficient for at least 5 years of routine operation.
