plan heating axles and spindle

[LuisVito]

Hello everyone!

I have to make a fanuc 0m progamate that performs the heating of the chuck and xy axes.

for the spindle there are no problems since I use the g04 to increase the turns gradually (g04 x...;m3 s1000;g04 x...;ecc). the problem lies in the heating axes, in practice I have to move the axes forward and behind for at least 10min to warm the flat guides on turquoises.

I look for advice

Thank you! !

Hi.
put the axle movements you want to heat
in a subprogram and repeat everything you want.

Hi.
you have to generate a program warm-upthat lasts 10-15 min. which uses all the race of the table in x and y
and if you want to
also serves to strend the oil to lose in the quids and bars
Thank you very much

Yes, but I'm not able to make a program that countmps. all 2 things....

Watch the z movements!
Since it should be a program loaded always in the car and to use always, regardless of the equipment mounted on the table, it is necessary to make sure that when moving in x/y the axis z is in the position more distant from the table, then to make him do the maximum of the + racing and - after having brought the table in a position where there is no danger of collisions.

Of course, also be careful not to have any tools mounted on the spindle (imagine what happens with the head that goes towards the minimum of the z with mounted on a beautiful 300 mm long bare), but at the most with a cone that does as a "tape" and that allows to rotate the spindle, which on some machines without any loaded cone can not rotate over a certain number of turns, usually no more than 100.

It is not a difficult program to write, with a moment of patience you do it and then it is good for the whole life of the machine and, properly changing the quotas of the movements, it is also valid for all the machines of the workshop.

a curiosity. Is it normal practice in the workshops to heat the machines? i.e., for the purposes of processing even the operating temperature of the machine is important?

depends on what you are going to do.
If the car was stopped for more than three days, it always does.
if it has been firm for 8-10 hours and the work to carry out is not particularly accurate, you can also omit.
Regardless of everything if you exceed during processing the 6000g/min you must always do it.

These are the provisions given to us by the builder on the centers where I work.

Thank you. I am not very practical of various tricks and knowing this information is always convenient.

depends also on the machine you have and the type of spindle, for example this year in bimu I witnessed a demonstration of a makine with 60000giri/min electron and they, thanks to numerous patents, guarantee that they are never indispensable preheating.... that translated means that in the morning turn on the machine s60000 m3 and via:finger:

 

[vincenzoquovadis]

the "okk 800 and 1000", have timers that turn on the car half an hour before the turn starting already with the warm-up program.

of vital importance is to turn them off in the evening with a balanced cone...otherwise...

makinos are a world apart...:finger:

I still refer to electro-mandrini with ceramic bearings.
in the case of spindles (transported) from 4000g/min. It doesn't help the preheat.
