| ‘ | High-precision, spindle-fixed CNC lathe with maximum bar capacity of Σ20mm. |
| ‘ | A hollow air chucking cylinder for the main spindle and the ring & cone mechanism for the sub-spindle are employed to lessen thermal influences, such as oil temperature fluctuation. |
| ‘ | To prevent coolant from making contact with the bed, the coolant chamber is isolated with a double-structure. |
| ‘ | Pre-tension is applied to ball screws of all axes (X, Z and A). The X-axis that directly affects the radial accuracy has a heat-balance construction equipped with as short a ball screw as possible to diminish thermal elongation. |
| ‘ | High-speed specification (max. 8,000min-1 for main spindle and sub-spindle) assures efficient turning operation for small-diameter, non-ferrous workpieces. |
