Pick-up principle
The spindle picks up and deposits the part itself; the integrated 2-axis handling unit with swivel unit keeps the footprint compact.

Why UNIVERTOR AC?
Turning and grinding combined
Optional internal and external grinding spindles, 4-axis machining with a second turret on the cross slide, multi-spindle drilling heads and a Y-A axis unit for gear milling.
Precision
Direct measuring with glass scales in all machining axes and high-accuracy, preloaded linear guides; guides and feed drives sit outside the working area, protected from chips.
Variants
AC-1
Single spindle; right- or left-hand machine
Suited to: Complete machining of varying batch sizes with high quality requirements
AC-2
Two spindles: two parts machined simultaneously, or one part in two clampings (with part turnover); machine halves can be separated to a certain extent
Suited to: OP10/OP20 two-clamping jobs and two parts at once

Frequently asked questions
What is the difference between the AC-1 and the AC-2?
The AC-1 has one spindle. The AC-2 uses two spindles to machine two parts simultaneously or one part in two clampings. Turning diameter, spindle and turret data are the same for both.
How does the UNIVERTOR AC differ from the UNIVERTOR AM?
The AC is for smaller parts with Ø 150 mm turning and 215 mm chuck diameter; its A6 spindle (90 mm bearing) reaches 4,500 rpm. The AM handles larger parts with Ø 360 mm turning and 410 mm chuck diameter; its A8 spindle (120 mm bearing) runs to 3,500 rpm and delivers 40 kW and 610 Nm at 40 % duty cycle.
Can turning and grinding be done in one clamping?
Yes; internal and external grinding spindles are available as options. In the manufacturer's example all functional surfaces of a bearing inner ring are turned and ground in one clamping, with a cycle time of about 50 s depending on size and machining scope.
