    What are the Functions of ATC Spindle Motor?

    With the development of industrial technology, automation has gradually become the main form of enterprise production and processing. In machining, the tool needs to be changed frequently due to different materials or shapes. The high speed motorized spindle has also been continuously developed from the traditional manual tool change to the ATC.

    The rear end of the electric spindle is a cylinder structure. It uses air pressure to push the thimble against the middle pull rod so that the collet extends outward and the tool falls off, and then the device can automatically grab the tool using the shaft platform. The rear end of the spindle uses a solenoid valve to release the air and cut off the air so that the tool is clamped. This process is called automatic tool change.

    Tool change speed has become an important index of high-level machining. Compared with an ordinary motorized spindle, the advantage of ATC spindle motor is that when the tool is changed relatively frequently, it eliminates the cumbersome process of manual tool change, completes the tool change more quickly and accurately, and greatly improves the production efficiency. Therefore, when selecting spindle motors, in addition to the speed and power, the tool change mode is also one of the decisive factors for selecting the correct spindle.

    ATC Spindle

    The automatic tool change spindle can change the tool according to different processing requirements, so as to realize the automatic completion of complex multi-process. The automatic tool changer is widely used and is the development trend of high speed CNC spindle motors in the future. It also has the following functions.

    Speed regulation:

    The electric spindle must have a certain speed regulation range and realize stepless speed change, so as to ensure that a reasonable cutting amount is selected when processing raw materials, so as to 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 machining center spindle system must have the function of automatic tool clamping compared with other spindle systems. The realization of the tool change function can ensure that the spindle can use suitable tools in different use environments.

    Spindle positioning:

    The precise stop function of the electric spindle is also called the positioning function of the spindle. 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 end face key of the tool holder, which is the function that requires the spindle to be accurately positioned at a specific angle on the circumference. This specific electro-spindle function is used in conjunction with the automatic tool change function. offers multifunctional three phase 0.35 kW, ISO30 9 kW and 12 kW air cooled ATC spindle motors at low prices. Low noise 3 phase 1.5 kW, 1.8 kW, 4 kW, 5.5 kW with ISO25 and 7.5 kW BT30 water cooled ATC spindles are available. They are suitable for CNC routers, engraving machines, high-speed and high precision milling, drilling and tapping of metal and non-metallic materials.
