I am trying to determine what is considered a normal operating temperature for the spindle motor body?
I am also trying to determine an optimal feed/speed recipe for 6061 Aluminium? Other than the initial feed/speed chart referenced below, I cannot find much for the V2-10.
I am also trying to determine if 4 hours is an acceptable tool path duration for a 2d Facing operation to clear away a 2" x 1.75" x .25" section of stock? (I will share the .f3d if someone cares to review it)
Based on the V2-10 specs, it is using a BLDC 3 Phase with Hall Feedback spindle motor.
This is the best reference I can find for the motor specs. BLDC 3 Phase with Hall Feedback
On pages 17-18, the max temperature listed is 80 Celsius / 176 Fahrenheit.
Using a Fluke - 62 mini IR Thermometer, I am getting a continuous reading of 135 Fahrenheit on the spindle motor side body.
I have tested with many DOC/WOC variations while milling 2" x 2" 6061 Aluminum stock and Datron single flute 3mm bit purchased from the pocketnc store.
Test variations based on initial feeds/speeds chart.
8500 spindle speed
0.0008 (in) feed per tooth and using climb for tool direction
feed rate = 6.8 inpm
tool path = 2d Facing
WOC = 10%, DOC = 90%
Observations = Very Loud!!!, the spindle chatters 3 or 4 times per each 2 inch line run, the final surface finish of the resulting face is rough with cut line pattern very jagged. Spindle body temp = 135 Fahrenheit.
WOC = 10%, DOC = 50%
Observations = Not as loud, the spindle has only chattered once or twice during a multi step down facing operation (4 hours). The final surface finish of the resulting face is smooth and cut line patterns are all parallel with no noticeable jaggedness. Spindle body temp = 135 Fahrenheit.
Any tips or course correction that the community or pocketnc staff can offer would be much appreciated. This is one of the most expensive desktop hobbies that I have invested in and I really don’t want to be disappointed. with the investment.
