B axis with 3 rotary tools on the gang tool post (type VIII)
The B axis is the slant axis in reference to the Y axis direction. When drilling a slanted hole on a conventional machine the adjustable angle spindle was required, but now rotary tools incorporating a B axis can be used to change the angle continuously allowing you to handle slanted holes at a number of angles. Contouring with simultaneous 4-axis control is also possible (the angle range is -10° to 95°).

Improved turret capability
The turret geometry is carried over from the previous generation to deliver tool holder compatibility. An improved Z2 axis stroke allows simultaneous machining with opposed turning tools or rotary tools on the gang tool post thus enabling pinch/balanced turning and pinch/balanced cross drilling and milling. Turret indexing can take place in any position which reduces cycle time.

Y axis on the back tool post (types VII and VIII)
The back tool post can accommodate holders at 3 positions (2 positions for rotary tools and one for fixed tools) and up to nine tools can be used. All 3 rows are under Y3 axis control. The specifications of the outer diameter milling spindle (GSC1110), 3-drilling spindle (GSE1510) and 3-sleeve holder (GDF1501) are common to those used on the gang tool post and they can be used both on the gang tool post and the back tool post.
