    Tips: 3 Functions of ATC Spindle

    • Speed control

    In order to meet the requirements of different processes, various workpiece materials and cutting tools, etc., the electric spindle must have a certain speed range and realize stepless speed change, so as to ensure the selection of reasonable cutting amount when processing raw materials, and obtain good cutting efficiency, Machining accuracy and surface quality.

    • Automatic tool clamping

    The outstanding feature of electric spindle machining is the automatic tool change function. In order to ensure the continuous implementation of the machining process, the spindle system of the machining center must have automatic tool clamping compared with other spindle systems. The tool change function can ensure that the spindle uses tools suitable for the situation in different use environments, and that the electric spindle can better adapt to the characteristics of the environment.

    • Spindle positioning

    That is, when the spindle stops, control the spindle to stop at a fixed position, which is a necessary function for automatic tool change. During automatic tool change, the cutting torque is usually transmitted through the face key of the tool holder, which requires the spindle to have the function of accurately positioning at a specific angle on the circumference. This specific electric spindle function is used in conjunction with the automatic tool change function.

    Great CNC spindle
    This cheap automatic tool changer spindle is definitely better than I thought it would be. In my case, I use it to replace the AC motor on a CNC mill. You don't need ear protection when it's running, it's quiet even at 24,000 rpm.
