NILES-SIMMONS N20 CM - Crankshaft Milling Center

Two symmetrically arranged tool spindles with electronically synchronized torque drives and two compact and powerful milling units ensure rough and finish milling operations on crankshaft main and pin bearing journals by means of these milling centers. Electronic gearbox and high precision interpolation of spindle systems as well as special compensation strategies enable process capable manufacture of high precision bearing geometries.
The NILES-SIMMONS CM Series for crankshafts from 500mm up to 1.200mm.

I was in Crankshaft machining most of my working life, when I first started on the Cranklines, this particular op needed 6 separate ops to get to this stage..
When I retired we were using these CNC Boehringers ..
Nothing like the original double headed mills that both Heller & Boehringer were producing at that time..
I’ve been retired 8 years so I’m guessing these particular machines maybe passed their sell by dates !! 😂

Boehringers were superb. We had also T-turn broaching Boehringers. Still running...

[@smokeysghost4759]

That’s the most impressive crankshaft CNC I’ve seen !
Have done billets in this machine ?

[@ajingolk7716]

Nice but it look like its only for forged cranks😢

[@LampuSachin299]

It's an amazing machine. what is the maximum eccentricity the machine accommodate?

[@TheNSHGroup]

Thanks Atul! You can check out our Homepage www.niles-simmons.com for more details. Regarding your question: Eccentricity depends on the dia. of rod bearing and cutters / tools.
So there are a lot of options. We have a max. eccentricity of 65mm or 70mm most commonly at the N20 series. Hope that helps. Best regards!

Thank you.
