Broaching reaches its limits when the material of the part to be machined has a very high tensile strength. This is where milling with the Schwanog PWP system has proven its effectiveness. With the 2-edged insertable tool, grooves can be milled with a precision of ± 0.01mm. Thanks to the quick-change capability of the inserts and a high changeover accuracy, machining can usually be continued immediately after a tool change without readjustment.
