how can we make a optinal economical cnc machining
It take us 9 hours 15 days for 120 pcs it is a heat sink.
Scheduling, calculating time, multiple clamping setups, and worst of all – non-stop shifts!
But precision control and data inspection can’t be ignored。 Heat dissipation fins possibly loose tolerances, but boss height and circular port interfaces much be accurate.especially the down sure-face.
Why so time costly？
It have Two surfaces to machine, thus Two twice clamping setups.
due to it is such big part.
The cutter must feed slowly to achieve a glossy surface finish. Process specifications need to consider.
Why not 5axis machining it will be faster and only one clamping？
Oh no 5 axis machining is costly.to save the cost we make them by 3 axis machining.
But if we make mold casting, shallow milling produce faster.
The problem is that up to the qty.
How we do it.
the heatsink first Rough then milling.
Finally, we can optional, IP grade, treatment finished, Nickel Plating，Electrophoresis ect.
Look this parts,do u think it use in motor vehicle,computer, or robot?
Answer, motor vehicle
