Now we're going to cover some basic maintenance and upkeep of your 4th axis rotary table.
One of the first things you need to do before running your rotary...
...table is to make sure it's oiled. The standard table is what we are going to be focusing on today.
So the standard rotary tables have two oil ports. They have one oil point here, and one here.
The standard rotary tables also have an oil fill port.
To fill the standard rotary table with oil,
simply remove the oil fill cap and in this position you would fill the unit...
...with oil until you see a little bit running down the front of the unit.
That's when the oil reservoir is full.
Depending on which unit you purchase each rotary table has...
...different locations for oil ports.
Check the Owner's Manual to find out where yours are located.
Now we are going to talk about backlash.
Backlash needs to be adjusted on your table when you first receive it.
It is not set from the factory.
It is your responsibility to set backlash .
The procedure I'm going to show you is the quick and dirty way to get it close.
Then I recommend following procedure in the owners manual.
On how to set it by the numbers.
So today we're going to be working with new style as of 2015 backlash adjustment.
If you don't have this style please refer back to the owner's manual and adjust backlash accordingly.
The first thing you need to do is make sure that your motor is free,
the eccentric is free to rotate, and lightly engaged. Second thing you need is...
a wrench or socket on a spinner handle, or ratchet, and loosen...
the outer nut. Now you're ready to adjust the backlash.
First thing I always recommend...
..is to back the adjustment screw out a ways, so you can make sure that the motor is...
...engaging into the ring gear. Then simply start by turning in...
keeping a light grip on the motor, turn the unit in.
Until you feel a slight resistance on the screw.
So continue to turn the motor in until you feel a stop.
At this point, the dog-point set-screw is against the eccentric.
For a slight quick adjustment,
give it about one quarter of a turn.
This is quick and dirty part. This has got you...
...probably right around sixty arc seconds.
So if you're gonna set it up by the numbers,
you don't need to lock down the backlash adjustment screw.
If the quick and dirty method is good enough for you...
you'll need to lock down the backlash adjustment screw to try and keep...
...it in adjustment for a longer period of time once you're back
Once your backlash has been adjusted you'll want to lock your eccentric.
This will help ensure that the backlash adjustments you just made don't come out.
The way I would do this is to take a socket, place it over the nut,
Place the screwdriver through..
...the socket...
and snug the nut down.
Once that has been done you can put the spinner handle back on and tighten it.
That's the quick and dirty way to get it close to 60 arc seconds
Tormach recommends between 60 and 80 arc seconds of backlash in the rotary tables.
At this point I recommend you go to the manual...
...and follow the procedures for setting it by the numbers.
So this is just the basic rundown of the rotary tables
and accessories for the rotary tables we offer.
