Fully automatic CNC-controlled key milling machines

Fully automatic CNC-controlled key longitudinal profile milling machine

Patented process - cycle time 5.5 sec
With this system, AUMAT offers a patented solution for milling variable key longitudinal profiles for master key systems. Thanks to a patented milling process, only a limited number of shank profile cutters are required despite the high number of variants. This results in several advantages:

This results in several advantages:

Reduced costs for cutter procurement and sharpening
Low effort required for cutter adjustment
Reduced setup times
Better accessibility to the stations
Favorable conditions for chip extraction

This is how the patented milling process works:
The (identical) milling stations are arranged in the required number for the first shank side of the key (e.g., 3 or 4 units) peripherally around a precision rotary indexing table, and the same again for the second shank side.
Each station has only a single cutter. As a rule, this has 4 milling segments offset in the axial direction, of which only one milling segment engages per milling pass (shifted under control).
In this way, each station mills 2 variants of the shank, e.g., A and B, according to the rule "with A/with B - without A/without B - with A/without B - without B/with A".
