Adding dwell time before being able to open door

[APFL]

Hi Everyone,

First post so hoping someone can help.

We have two Mazaks, one QT18 and one QT 28 CNC lathes from early to mid 90's using Mazatrol T32-2 easy programming.

Since the new legislation regarding misting of coolants in the UK and operator safety, we now use Filtermist LEV extraction systems that give a time from when the machine stops to when you can open the door i.e. 17 seconds to ensure all coolant misting is removed from the cabinet before opening the door.

I would like to add a line to the end of the program that will keep the door locked for 17s after machining but can't work out how, we use a dwell G04 on our Doosan DN650 with P32000 for 32 seconds and was hoping to do the same but can't manage to add anything that resembles this.

Can someone please point me in the correct direction or a step by step guide on how to add something suitable using the Mazatrol T32-2 programming.

Many thanks in advance.

Make a manual process (MNP) before the end process at the bottom of the program. Just make a line with no motion add G4 dwell X17.0 for 17 seconds.

Wow, that's interesting legislation.

Wow, that's interesting legislation.

And, while I'm not a believer in excess legislation I think it a good idea to limit operator exposure to coolant mist.

Thanks for the reply, I'll give that a go and see how I get on......might be back for more help if I can't get it to work. Thanks again
