KCS-70C Fully Automatic Circular Saw Bar Cutting Machine

The KEENSAW KCS-70C is a high-speed, fully automatic CNC circular cold sawing machine engineered specifically for precision mass cutoff of solid metal bars, billets, square stock, and heavy-walled tubing up to φ70mm in diameter. Combining a ultra-rigid cast-iron chassis with advanced AC servo motor drives for both material feeding and downfeed cutting, the KCS-70C maintains exceptional linear cutoff tolerances within ±0.05mm while producing clean, mirror-smooth cut faces with zero burrs.

Designed as a complete turnkey automated cell, the KCS-70C seamlessly executes auto-loading, auto-feeding, auto-cutting, and auto-unloading. For standard φ50mm mild steel solid bar (20mm cutoff length), cutting takes just 3.7 seconds per piece (4.8s total cycle time), allowing a single machine unit to yield approximately 6,000 finished pieces per 8-hour shift. With its intelligent PLC interface, a single operator can easily monitor up to 4 KCS-70C machine units simultaneously.

Frequently Asked Questions: KCS-70C Automatic Cold Saw

Q1: What workpiece geometries and material grades can the KCS-70C cut?
A: The KCS-70C is engineered to process solid round bars, square bars, hollow pipes, billets, and H-beams. It easily cuts carbon steel, stainless steel, titanium alloys, and nickel-based high-temperature alloys up to φ70mm in size.

Q2: Is the machine driven by hydraulics or servo motors, and what accuracy is achieved?
A: Both material feeding and blade downfeed cutting actions are driven by high-torque AC servo motors. This dual-servo architecture ensures extremely high linear cutoff accuracy within ±0.05mm with smooth, vibration-free blade travel.

Q3: Is the automatic magazine loader table included in the quote?
A: Yes. The KCS-70C comes standard as a full automated system: auto-loading incline magazine table, auto-feeding shuttle, auto-cutting head, and automatic remnant discharge separator.

Q4: What surface quality can be expected, and is secondary deburring required?
A: The KCS-70C produces a mirror-smooth cut surface with zero burrs. Secondary deburring or facing operations are completely unnecessary.

Q5: What saw blade does the KCS-70C use, and what is its operational lifespan?
A: The machine utilizes premium TCT carbide saw blades (e.g., φ285*60T, approx. $100 USD per piece). On standard φ50mm mild steel, a new blade yields around 17,850 cuts (35 m² cut area). With 2 standard resharpenings, total blade yield reaches 35,700 to 42,840 cuts (70–84 m² total cut area).

Q6: What warranty policy, leading time, and after-sales support are provided?
A: Standard manufacturing lead time is 30 days. KEENSAW provides a 12-month factory warranty, 1 free spare parts package (sufficient for at least 5 years of operation), lifetime technical consultation, and 24/7 online technical support with response guaranteed within 24 hours.
