Machine Features & Engineering Advantages
Advanced Motion Control
Equipped with Yaskawa inverters for both the 5 HP spindle and full-axes control, delivering seamless variable speed transitions and high torque at low RPM.
Robust Mechanical Architecture
Hybrid slideways feature Dovetail ways (X-axis) for smooth movement and Box ways (Y & Z axes) for maximum rigidity during heavy milling.
Precision & Versatility
High-grade ball screws ensure minimal backlash. The head tilts 90° for complex angled boring and side-milling without multiple setups.
Industrial Durability
Standard specialized Y-front steel way covers, automatic lubrication, and integrated auto-coolant systems ensure thermal stability and long lifespan.
Machine Features
The WS-NC4A represents the pinnacle of the KM Series, blending the classis tactile feedback of a conventional knee mill with the high-torque precision of 3-axis NC control. Engineered for heavy-duty toolroom applications, it the definitive solution for complex prototyping, mold repair, and high-precision educational training.
Core Engineering & Advantages
Advanced Motion Control & Drive System – The WS-NC4A is built for modern manufacturing. By integrating Yaskawa inverters for both the 5 HP spindle and full-axes control, the machine delivers seamless variable speed transitions and high torque at low RPM.
Precision Hardware – Equipped with high-grade ball screws on all axes to ensure minimal backlash and high repeatability.
NC Versatility – Full compatible with industry-standard controllers such as Fagor and Siemens, allowing for easy integration into existing CNC workflows.
Robust Mechanical Architecture – Designed for heavy-duty is not just a claim, it is baked into the casting:
Hybrid Slideways – Featuring Dovetail ways on the X-axis for smooth movement and Box ways on the Y & Z axes for maximum rigidity during heady milling operations.
Head Versatility – The head tilts 90〫Right / Left , providing the flexibility required for angled boring and complex side-milling without multiple setups.
Industrial Durability & Protection:
Way Protection – A specialized Y-front steel way cover protects the precision surfaces from hot chips and coolant, extending the machine’s lifespan.
Automated System – Standard configuration includes and automatic lubrication system and an integrated auto-coolant system, ensuring thermal stability and reducing manual maintenance overhead.
