- Modern mono-block frame made of Meehanite casting ensures excellent geometric accuracy and provides a large work area
- All machine frame assemblies, like base, column, saddle and table, feature heavy ribbing and excellent rigidity
- Rigid table design with extra wide saddle supporting the table and allowing table loads up to 3968 lb
- In addition to wide 4X box-ways on Y, the machine base features support guides for the saddle, allowing maximum precision even under uneven table load distribution
- All guideways are ground, hardened, counter-laminated with Turcite-B, and protected by premium stainless steel covers
- Z axis drive operates with a fine-tuned counter-balance for high-precision response and minimal motor and guide wear
- Preloaded ball screws with 2.5 in diameter on all axes
- Custom bearing block on its own linear guide system at the X axis spindle prevents vibration and torsional effects to ensure a constantly uniform feed
