All cone connections with the taper bore of the work spindle without using the drawbar is not permissible for milling operations.

  • Page 31: 4.9.5 Use Of Collets

    4.9.5 Use of collets When using collets for the reception of milling tools, a higher operation tolerance can be achieved. The exchange of the collet for a smaller or larger end mill cutter is performed simply and rapidly and it is not necessary to remove the complete tool. The collet is pressed into the ring of the swivel nut and must rest there by itself.

  • Page 32: Selecting The Speed

    The optimum cutting speed largely depends on the material of the workpiece and the material the tool is made of. With tools (milling cutters) made of hard metal or ceramic insert it is possi- ble to work with higher speeds than with tools made of high-alloy high speed steel (HSS).
