Super Rigidity Turning Centers
The low center of gravity 30° true slant bed design provides a very rigid
foundation for the headstock, turret, and tailstock.
20 HP high power, 2-speed motor configuration further increases the spindle’s
cutting ability and flexibility.
A high-speed servo motor indexing turret achieving 0.2 second indexing times for
adjacent stations and 0.5 second for stations at the opposite end of the disk.
Available programmable base tailstock enables many critical applications to
be performed efficiently.
Maximum Strength Construction
Slide ways are bonded with "Turcite B" to eliminate stickslip, minimize wear and maintain long term accuracy.
