- Complete Portal Type Structure – Both fixed crossrail and crossrail lifted types employ the portal type structure which provides unmatched rigidity with accuracy repeated for years to come.
- Angle Attachment – Similar to the turning tool holder, the high rigid type angle attachment is positioned and clamped on the main center clamp & by the sub-clamping system at the 4 corners of the ram end, making it possible for accurate positioning.
- Y Axis Mechanism – As the large diameter ball screw is used for the Y Axis drive and the turning drive employs a large diameter ball spline, the machine can achieve smooth feed drive with a low maintenance long rigidity.
