Automatic Tool Changer

Change station WK 19
Cone change station WK 19: During the tool change process, the station automatically moves to the top, during the machining process it is protected by the lid from chips and oil mist.

You can increase the speed of your whole production process by changing the tools automatically. Your milling machine will work with greater effectiveness when your jobs can be processed without interruption.

All pneumatic high frequency spindles and rotary current spindles (P models) can be equipped with an automatic tool change station.

After a change, the length of each carbide tool will be measured automatically with the measuring key. This procedure ensures that the dipping depth that has been set once, will be applied exactly to all tools, even if they differ in length.

High frequency spindles
If you have high frequency spindles, only the tool itself will be exchanged. It has to be equipped with a stop ring and will be placed in an appropriate tool fitting. This solution is space-saving and enables a greater number of tools to be changed.

Rotary current spindles
If you have rotary current spindles, a cone (WK 19/SK 30) will be exchanged. It holds the collet chuck which holds the tool. So there are no stop rings or reducing bushes necessary, but this solution demands more space. However, depending on the actual circumstances there are numerous individual solutions possible.




  • Technical data

    high frequency spindles

    • usable with all high frequency spindles with pneumatic collet chuck (P models)
    • 7, 9, 19, 29 or 39 resilient tool fittings for tools with up to 6 mm shank diameter and stop ring
    • adaptation to other shank diameters with reducing bushes possible
    • precise measuring key with an accuracy of 0.01 mm for exact determination of tool length (automatic interpretation by controller)
    • optional: automatically controlled pneumatic aluminium cap for protecting the tool fittings from chips and from oil mist when using lubricants

    rotary current spindles SPC 1500P, SPC 2300P (WK 19)

    • pneumatically in z direction movable tool change station with 4, 9 or 14 resilient fittings for WK 19 cones; the full retractability into the machine table saves passage height
    • protected by automatically controlled pneumatic cover
    • tool diameter only depends on the inserted collet chuck (up to 10 mm)
    • precise measuring key with an accuracy of 0.01 mm for exact determination of tool length (automatic interpretation by controller)

    rotary current spindles SPC 3800P, SPC 5500P (SK 30)

    • pneumatically in z direction movable tool change station with 4, 9 or 14 resilient fittings for SK 30 cones; the full retractability into the machine table saves passage height
    • protected by automatically controlled pneumatic cover
    • tool diameter only depends on the inserted collet chuck (up to 20 mm)
    • precise measuring key with an accuracy of 0.01 mm for exact determination of tool length (automatic interpretation by controller)
  • Requirements

    Please note that the tool change station has to be mounted within the positioning range of your milling machine, so the usable area for machining will be limited. Depending on size and position of the tool change stations, these limitations will vary.

    Furthermore, its is not possible to use all tool change stations on all model ranges. Our basic systems are generally designed in a way that the positioning range is big enough so that a tool change station for high frequency spindles or WK 19 cones fits next to a vacuum table. The SK 30 cone change of SPC 3800P or SPC 5500P requires most space, so it will usually be placed in a separate tool change area. Please see also the adjoining table.
