As a 3-Axis short tail type carbide circular saw, the high-speed carbide circular saw KCS-70A with the tail length is only 20～20+α(cutting length), greatly save material and save processing time, compared with 2-Axis series which only have two servo motors, the feeding servo motor, the cutting servo motor, this type has the 3rd servo motor which in front of the main clamping device, through the 3rd servo motor, it clamped the material and pull out, till the cutting length, which ramains a short tail behind.

The KEENSAW KCS-70A is a high-precision, heavy-duty CNC automatic circular cold saw engineered specifically for high-volume cutoff operations on solid metal bars, billets, square stock, and heavy-walled tubing up to φ70mm in diameter. Featuring an ultra-rigid A-series machine frame with dynamic dual AC servo-motor drives, the KCS-70A secures consistent positioning and linear cutoff accuracy within ±0.05mm, producing mirror-smooth cut surfaces with zero burrs that eliminate secondary facing operations.
Designed for continuous 24/7 automated production, the KCS-70A 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), outputting up to 6,000 finished parts per 8-hour shift. Integrated with an automated magazine loader and intuitive PLC touchscreen, a single workshop operator can effortlessly run up to 4 KCS-70A machine units simultaneously.
Built under strict ISO9001:2000 quality systems and certified to international CE standards, every KEENSAW KCS-70A unit comes standard with the automatic magazine loading table included in the base machine price, providing immediate ROI without extra automated accessory costs.
Review the operational benchmarks delivered by the KCS-70A CNC bar cutting saw when processing φ50mm solid mild steel bar stock:
| Key Metric | KCS-70A Engineering Standard | Shop Floor Advantage |
|---|---|---|
| Cutting Speed & Cycle Time | 3.7s cut / 4.8s total cycle (~6,000 pcs / 8 hrs) | Replaces multiple conventional band saws with 1 automated line |
| Linear Cutting Tolerance | ±0.05mm (Full Servo Drive) | Eliminates material waste and secondary end-facing grinding |
| TCT Blade Service Life | 17,850 cuts original / Up to 42,840 cuts (2 resharpenings) | Drives consumable costs down to under $0.003 USD per cut |
| Labor Reduction Index | 1 Operator runs 4 KCS-70A Machine Sets | Maximizes factory productivity while slashing labor overhead |
To withstand high-torque solid bar cutting loads in 24/7 continuous operation, the KCS-70A integrates top-tier components from global industry leaders:
Every KCS-70A purchase is backed by KEENSAW’s complete global support package:
Looking to streamline your solid bar cutting line with ±0.05mm accuracy?
Q1: What material types and shapes can the KEENSAW KCS-70A cut?
A: The KCS-70A is specifically engineered for solid round bars, billets, square stock, and heavy-walled tubing in carbon steel, stainless steel, titanium alloys, and nickel-based high-temp alloys up to φ70mm in diameter.
Q2: Is the automatic magazine loader included with the KCS-70A?
A: Yes. The base price includes the complete automated system: incline magazine loading table, auto-feeding shuttle, auto-cutting station, and automatic remnant discharge conveyor.
Q3: How accurate is the cutting length tolerance on the KCS-70A?
A: Powered by precision AC servo motors driving the shuttle feeding and downfeed cutting head, the KCS-70A maintains strict linear tolerances within ±0.05mm.
Q4: Is secondary deburring needed for parts cut on the KCS-70A?
A: No. The KCS-70A leaves zero burrs and achieves a mirror-smooth cut surface, eliminating secondary deburring or end-facing operations.
Q5: What warranty and after-sales service does KEENSAW provide for the KCS-70A?
A: KEENSAW offers a 12-month full warranty, lifetime free technical consultation, 24/7 technical online support with response within 24 hours, and 1 complimentary spare parts package sufficient for at least 5 years of operation.
