High-speed spindle can be divided into eight categories : grinding spindle, milling spindle, turning spindle, spindle pull grind , drill spindle, spindle machining center , machine spindle ( excluding built-in motor ) belt drive spindle , special spindle rotation test and so on. Users commonly used grinding spindle, milling spindle, turning spindle, spindle machining center , machine spindle (without built-in motor ) belt drive spindle five.
When you have a choice spindle, be sure to pay attention to your applications, different applications of the interface is different , and the other must understand your power requirements , and the corresponding speed in this power , which is very critical , because the same is 1KW, at 1000 rpm and 10,000 rpm spindle dimensions requires a lot of difference , so the condition must be accurate . There is also a need to pay attention to the tool interface must be clear , this is a principled , under normal circumstances BT50 interface speed can only be used in the following 8000RPM spindle in , BT40 spindle interface can be in the 18000RPM under use , if you want more speed, you need to select the appropriate tool interfaces HSK tool interfaces such as high speed , CNC milling spindle is equipped with the ER collet chuck or collet chuck is a certain SD allowable maximum speed .
Grinding spindle relations are generally constant torque motor, the motor 's maximum speed and power and voltage design is a geometric relationship between voltage and power increases linearly with increasing spindle speed . Constant current to maintain basic , because the relationship between torque and current relationship is linear , so call this system of constant torque spindle motor system . Usually both the grinding spindle speed range is relatively small, the maximum speed is normally 80% to 100 % , while also taking into account the maximum allowable speed of the wheel with the line , and therefore generally can not be used when only a small high-speed and low speed large wheel wheel, or because of low power is not big enough lead to effectiveness and efficiency of large grinding wheel is relatively low , in addition to its own weight due to the large wheel , high-speed spindle bearing load capacity can not meet their requirements which led to drastically reduced spindle bearing life , precision life is greatly shortened. Milling spindle and spindle machining center designed torque and constant power exercise and generally matched to meet the needs of a wide cutting speed range , low speed high torque needed for heavy cutting , high-speed precision machining requires a certain power , so the motor system and grinding cutting spindle , which are quite different .
