Littlemachineshop Mill

[David Da Costa]

I have just received my Littlemachineshop version of the Sieg KX1 and I am ready to start cutting.

My previous mill was a A2ZCNC upgraded Sherline and I would just like to get some feedback on cutting speeds/ feeds etc for the KX1.

I have read lots of threads here on feed rates etc and would just like to confirm the following should be okay.

I will be cutting 6061 aluminum with a 0.25" Fullerton Aluma-Mill carbide endmill with the following paremeters.

Mostly doing profile cutting

Roughing
1. Max spindle RPM 7,000 RPM
2. Feedrate 28ipm,
3 Plunge rate 5ipm
4. Depth of cut 0.125
5. Conventional cutting

Finishing
1. Max spindle RPM 7,000 RPM
2.Feedrate 15ipm,
3 Plunge rate 5ipm
4. Depth of cut = full depth (3/8")
5. Climb cutting


How do these numbers look?

Thanks


David

aluminum does not like conventional milling even for roughing better off climb for both> other wise looks good>
