Gears & splines
Gears and splines, cut without sending the part out.
Gear work normally means a second supplier, a second setup and a datum you have to re-establish. We cut gears and splines on the Multus — by skiving, broaching or gear milling — in the same clamping as the journals, faces and bores they have to run true to.

Other services
Not quite it?
Parts rarely fit one category cleanly. We'll route your job to whichever machine holds it best — that's the advantage of having all of them under one roof.
Why it comes out right
What you actually get.
Concentric by construction
When the spline and the journals it must run true to are cut in the same clamping, concentricity is a property of the setup rather than something you inspect and hope for.
No gear-shop handoff
Sending a part out for gear work adds a supplier, a lead time and a re-fixturing. Cutting it here removes all three.
Skiving for internal forms
Power skiving cuts internal gears and splines continuously, using synchronised rotation between tool and workpiece — which is exactly what a C-axis mill-turn with live tooling is for.
