* Spindle The spindle is supported by 4 class P4 super precision angular contact ball bearings that are permanently lubricated. The new spindle design includes circulation grooves on spindle with options for air and oil cooling.
* Table Guideway system Hardened and ground table guideway system with precision needle Roller bearings provide precise linear movement during rapid traverse.
* Counterbalance system A counterbalance in the spindle vertical drive prolongs ballscrew life and enhances downfeed accuracy.
* Base and saddle guideway system The base and saddle guideway systems use needle roller bearings running on heavy duty slide rails. The one-piece base casting has been stress relieved and finite element analyzed.
