EWS.Slot

Slot broaching on lathes is a common thing. What is new is to speed up this operation with low stress for the machine!

EWS-Slot is driven by the tool turret of the machine, with the input rotary motion being converted to a translation with superimposed lift-off function. This makes programming extremely easy. The slot broaching unit is positioned in the prepared bore – in such a way as to make the extended tappet oriented to the end position in the Z axis. The depth of the slot is produced by a constant X-feed moving between 0.04-0.08 mm/stroke.

The speed of the spindle ranges between 400 R/min – 1,000 R/min, with one rotation corresponding to a complete stroke.

This way, for instance, a feather key groove with a width of 6 mm and a depth of 5 mm is produced within 7.5 sec. (800 R/min and 0.05 mm feed/rotation).

With this operation it is important that the chip can break at the end of the groove, that is that a cut-in or a bore exists.

It is not only slots or grooves, but also internal and external teeth that can be produced. This is particularly interesting for tools with partial teeth.
