I am trying to understand the basics of milling while trying to put my DIY milling machine into use.
trying to mill 20 mm circle cut (2d tool path) in 8 mm steel plate
I used the following
feed rate : 90 mm/minutes
tool : 4mm end cut/ 4 flutes/carbide
stepdown : 0.1 mm
things going very well with no vibration please see the short video
My question : I have the metal shavings welded to the edge of the cut . Is it because I am not using cooling water? and running at high 5000 rpm. I do not see any indication of excessive temperature. I can touch the plate near the working area not hot at all. For sure the tool maybe very hot.
Second question : how do I remove the chips every few minutes? if I press the pause button on the axis interface screen and raise the tool up along z axis and clean the chips, and then hit resume button on the axis interface screen is this the proper way to do it?
Many thanks
Note :
1-this is not the spindle I intend to use. just for experimenting. Also I will place order for cooling mist nozzle.* I am only investigating the potential of the DIY machine to be or not to be.
2- The other holes in the plate you see are made by laser machine.
