Y-axis parting: turning re-invented

Get to know Y-axis parting – a completely new way of parting-off. While conventional parting-off uses feed motion along the X-axis with the cutting force directed through the weakest section of the blade, CoroCut® QD for Y-axis parting is designed with the top face of the insert perpendicular to the blade. This gives a more beneficial direction of the cutting force, resulting in considerably higher stability and reduced vibration.

CoroCut® QD for Y-axis parting is First Choice for parting-off in turning centers and multi-task machines with Y-axis. It can machine large diameters, up to 180 mm (7 inches), and is particularly suitable for long overhangs to reach between main- and sub-chuck.
