Z-W Overlap Function Reduces Cycle Time (Video)

Kevin Kraieski

If you take a look at the brief video shown here, you might do a double take. What on earth is this unusual process we’re showing? It’s a software option called Z-W Overlap Function that you can order for an Okuma CNC Lathe with a sub spindle. Z-W Overlap allows you to double up on some of your processes (mainly drilling) and reduce cycle time.

 

Watch the Video: Z-W Overlap Function

 

Normally on a single turret lathe with a sub spindle (W-axis), you’re only transferring the part from the main spindle to the sub spindle after completing all the machining on the main spindle. The sub spindle retracts back to its home position and the sub spindle work is then machined. 

What this function allows you to do is have two tools mounted in one turret station (one facing the main spindle and one facing the sub spindle) and allows you to feed the W-axis simultaneously while the Z-axis is cutting on the main spindle and synchronizes the Z-W feed rates. The result is you’re drilling a hole on two parts at the same time on both spindles with one turret station, which reduces cycle time and gives you a little higher productivity out of your machine.

If you’d like to learn more about this option, please contact us, or your local distributor.
