Samputensili SC 450 E CNC Gear Shaping Machine

The Samputensili SC 450 E is a CNC gear shaping machine built specifically for the production of internal and external cylindrical gears — including spur, helical, and cluster gear forms — with workpieces up to 450 mm in diameter. Unlike hobbing machines, the SC 450 E's reciprocating shaper cutter mechanism makes it the preferred choice for internal ring gears, blind shoulder gears, and cluster components where a continuous hobbing path is geometrically impossible.

Samputensili has equipped the SC 450 E with a fully electronic stroke drive replacing the conventional mechanical crank, enabling programmable stroke length, stroke frequency, and cutter lift-off angle — all adjustable on the fly from the Siemens SINUMERIK 840D sl control without mechanical intervention. This electronic stroke management delivers stroke rates up to 2,000 strokes per minute for small-module finish cuts and dramatically reduces the mechanical wear issues that plagued older hydraulic shaping machines.

The machine's helical guide is also CNC-controlled, allowing the cutting of helical gears up to 30° helix angle without physical guide change. This capability, combined with CNC-controlled radial infeed and tangential feed axes, makes the SC 450 E one of the most flexible gear shapers in its class — capable of producing a wide variety of gear forms from a single setup by updating the NC program rather than changing mechanical components.

Samputensili's long history in gear tooling — the company is also a major manufacturer of gear shaper cutters — means the SC 450 E is engineered with deep knowledge of tooling interaction, and the control includes tooling database management for rapid setup with known cutters. The machine is well established in European automotive and commercial vehicle gear production, and its rigid base casting supports the precision required for DIN class 5–7 accuracy across a wide range of module sizes.
