To brake or not to brake

Post by Mike B » Tue Aug 09, 2016 6:23 pm

I was working with a joiner recently who told me not to use the "STOP" button on my CMC spindle as it wears the brake out. Is this common practice?
ie. use the on.off power button instead. Trouble is you can start the spindle if the stop button is not in the stop position, safety first I would have thought.
Thanks,
Mike.

All "STOP" buttons are emergency stops in my opinion.
So with all my machinery if there is an alternative I will use it.
So the 4 sider is enclosed so I just power down and let it wind down rather than brake stop it. Saws I just use on / off which are DC braked anyway.
Have a look at my facebook page and leave a comment or two.

My spindle (which I have noticed now) stops at the same rate whichever button you press, so I guess there is no better alternative. I'll keep used the stop button as it prevents me turning the power on with my hand attatched.
Thanks for your imput.

You almost certainly have a mechanical brake which is applied by a spring and released by an electric current. Whichever way you remove the supply, the brake will activated which to be honest is they way it should be.
