ESCO NM647 Coil-Fed Automatic Lathe: High-Precision Used Machine for Sale | ESCO Lathe
The ESCO NM647 coil-fed automatic lathe is a high-performance precision lathe. We currently have one used unit available for sale, in very good condition, suitable for high-volume precision part production.
Key Features of the ESCO NM647
Coil (Reel) Material Feeding System
Unlike conventional Swiss-type lathes that use bar stock, the ESCO NM647 utilizes a coil (reel/bundle) material feeding system. The standout advantages include:
- Minimal remnant waste: Compared to traditional bar-fed Swiss lathes, coil feeding drastically reduces the material tail waste at each changeover
- Reduced non-production time: Coil material length far exceeds that of individual bars, significantly lowering the frequency of material changes and minimizing downtime
- Ideal for long-run batch production: One coil load enables extended continuous operation, greatly improving overall equipment effectiveness
Burr-Free Machining — No Tear-Off Nibs
The ESCO NM647's unique machining process ensures finished parts are free from tear-off nibs and burrs. This is critical for precision component manufacturing, eliminating the need for secondary deburring operations and improving first-pass yield.
Spinning Tool Design: Rotating Toolhead, Stationary Material
The ESCO NM647 employs a spinning tool lathe design (also known as a coil-fed automatic lathe):
- Material remains stationary: The workpiece material stays fixed while the headtool rotates tools around it at high speed for cutting
- Four tools on the headtool: A four-position tool layout capable of turning, forming, grooving, and more
- This design excels at machining long, slender shaft-type parts
Front Machining Unit (Drilling & Tapping)
The machine is equipped with a front machining unit capable of:
- Axial drilling operations
- Axial tapping (thread cutting)
Rear Machining Unit (Drilling & Milling)
A rear machining unit (sub-spindle) completes the following operations after part cut-off:
- Back drilling
- Back milling
- Back chamfering and forming
The combined front and rear machining capability allows complex parts to be fully completed on a single machine, eliminating the need for secondary fixturing.
High-Precision Cut-Off: Synchronized Main & Sub-Spindle Clamping
During the cut-off operation, both the main spindle collet and the sub-spindle collet clamp the part simultaneously, ensuring:
- Clean, flat cut-off surface with no stepping or burrs
- Exceptional cut-off accuracy and repeatability
- Prevention of micro-displacement during the cut-off moment
