CNC Spindle Maintenance Small Knowledge

- Jan 11, 2018 -

Here to popularize the electric spindle maintenance of small knowledge: spindle is divided into many categories, mechanical spindle, belt spindle, high-speed spindle and so on, electric spindle, common or belong to high-speed spindle, high-speed spindle can be stepless frequency conversion, high speed, of course, faster processing effect better.

The spindle of the machine is driven directly by the internal motor, the length of the main transmission chain of the machine tool is shortened to zero, the "0 drive" of the machine tool is realized, the transmission structure of the spindle motor and the machine tool spindle is combined, which makes the spindle part independent from the transmission system and the whole structure of the machine tool, and forms a "spindle unit" Electric spindle, the current main use of electric spindle is the AC high-frequency motor, so also known as "high-frequency spindle", because there is no intermediate transmission structure, sometimes called it "direct transmission spindle."

Motorized spindle has many advantages: compact structure, light weight, small inertia, small vibration, low noise, fast response, and high speed, power, simplified machine design, easy to achieve the spindle positioning, is a high speed spindle unit of an ideal structure.
