Superior Structural Rigidity
The spindle head sits as close as possible to the centre of the column, reducing overhang and bending moments. Structural deformation is minimized while cutting stability and machining accuracy are maximized.

MOVING-TABLE DOUBLE COLUMN MACHINING CENTER
Precision engineered for
heavy-duty machining.
Designed and manufactured entirely in-house, the FG Series combines more than three decades of engineering expertise with advanced manufacturing technologies. Every major structural component is optimized using finite element analysis (FEA) for exceptional rigidity, long-term accuracy and outstanding machining performance.
For large precision components, moulds and dies, and heavy industrial parts, FG delivers the stability, power and reliability required for demanding machining applications.
ENGINEERING DEEP DIVE
Engineered from
the ground up.
Integrated Structural Design
High-performance machine tools begin with superior structural design. Every FG Series machine is developed with a comprehensive understanding of machine dynamics, structural rigidity, thermal stability and manufacturing efficiency. This integrated philosophy ensures optimum cutting performance, superior surface finish and long-term machining accuracy throughout the machine's service life.
Optimized Double Column Structure
Heavy-Duty Z-Axis Box Guideway
The precision hand-scraped, one-piece box guideway minimizes vibration while maintaining stable accuracy under heavy cutting loads.
- Exceptional structural rigidity and damping.
- Long-term wear resistance and service life.
- Outstanding heavy-cutting capability.
High-Precision Class C3 Ballscrews
Premium Class C3 ballscrews are installed on all three linear axes and pre-tensioned for consistent machining precision.
- Outstanding positioning accuracy and repeatability.
- Reduced thermal deformation.
- Long-term positioning stability.
Optimized Structural Components
The base, table, saddle, beam and columns use high-grade Meehanite cast iron for vibration damping, rigidity, wear resistance and long-term dimensional stability.
Critical members are reinforced with high-strength steel plates and stress-relieved after welding to maximize structural integrity and machining performance.
