P20 – 250 NC Broaching Machine To Broach Keyways & Straight Sided Splines


Our P20-250-NC simplifies broaching of keyways and splines in through holes and blind bores. We use it mainly to broach up to 150mm long splines in parts with diameters up to 200mm. Its combination of the latest control technology with highly dynamic, guided positioning systems results in extremely accurate keyways and splines with an optimal surface finish. Our standard tolerances are H9 / P9 / JS9.

Designed for speed and flexibility either in mass production or small batches the P20-250-NC Broaching Machine precisely cuts 2mm up to 20mm wide and broachs up to 250mm long internal keyways, splines and other internal profiles.

Sturdy, low maintenance design

Built for mass production the P20-250-NC Broaching Machine incorporates years of shop floor experience and operators’ suggestions.

An integrated cross table permits easy positioning of pieces to machine.

Designed to mass produce keyways in blind bores, the workspace is completely closed off to prevent oil and chip projection and to facilitate cleaning.

The machine has been built in order to occupy the smallest space possible without lessening the easiness of use or the capacities, while increasing the operator’s productivity.

Easy programming – no NC code required

An embedded system controls all the machine functions. The programming is operator-friendly via a 15’’ touch screen. Easily-interpretable icons interactively request the few necessary input parameters (e.g. bore diameter, keyway width, and cutting depth) step-by-step. If required, these values can be optimized manually at any time.

Positioning and operation

A highly dynamic electrical motor positions the cutter automatically. The predetermined machining parameters automatically set broaching and retracting speed, cutting pressure, cutter feed and retraction. The parameters can be adapted manually in fine steps to match any requirements.

The broaching tools

The P20-250-NC Broaching Machine is purposely designed to operate the patented elmass® broaching system. All elmass® broaching tools are available in metric and imperial sizes. All metric and imperial components are interchangeable, thus minimizing tooling costs without compromising flexibility. Combining both the P20-250-NC Broaching Machine and the elmass® broaching system with its guided life tools results in the longest life and the highest performance and cost effectiveness in the hardest production environments.
