Jogging

Recently, I retrofitted my lathe with an inverter drive and it has transformed the machine. In common with other similar conversions it has a "jogging" function. What is the purpose of this "jogging" facility and how is it used to best advantage?

For all those times when you use the chuck as a 'handle' to move it round. In my view not so much use on a small lathe (or mill really) but jolly useful on a large machine. The larger the machine more useful it is… SteveW

You have to realise Mick that these inverters are primarily for use in industry and are therefore used on a wide range of machine types. The method is very much used in the printing and paper trades where a very large reel of paper is being fed into a machine, say for coating or for newspaper printing. In the past, and maybe now, this had to be done manually.

The paper would be fed between two rollers and if done with a continuous run button it would not be that difficult to take ones fingers in as well, A very slow, and non continuous, jog feature, makes it very much safer

I threaded the QC Toolpost stud using the Jog feature.

Very handy feature indeed.

Could, I think, be used to help in centering round stock in the 4-jaw, but haven't tried that yet. I'm still on a very steep re-aquaintance curve with regards to using a lathe.

Hi

Jog on my inverter reverses the motor. Higher and lower speeds are achieved using the up/down arrows. The jog function is very useful when using a die in the tailstock.

Jog speed is usually programmable to suit your needs.
