High-speed motorized spindle can be roughly divided into eight categories: grinding motorized spindle, the milling motorized spindle, turning motorized spindle, motorized spindle, motorized spindle electric spindle drilling, machining center, machine spindle (excluding built-in motor) belt drive main shaft, special spindle rotation test etc.User common grinding motorized spindle, motorized spindle, motorized spindle turning, milling machining center motorized spindle, machine spindle (excluding built-in motor) belt drive spindle five categories.
   Selective motorized spindle, must pay attention to your applications, different applications of the interface is different, also be sure to find out your power requirements, and under the power of the corresponding rotational speed, it is the key, because the same is 1 kw, at the request of the 1000 RPM and 1000 RPM of the motorized spindle shape size is differ a lot, so the condition must be accurate.There is a need to be aware of, tool interface must be clear, this is also a principled, usually BT50 interface speed can only be used under 8000 RPM of motorized spindle, BT40 interface can be used in the electric spindle of under 18000 RPM, if you want a higher speed, need to select appropriate high-speed cutting tools such as HSK tool interface interface, CNC milling on motorized spindle with ER collet chuck or SD collet chuck also has certain allowable maximum speed.
   Grinding motorized spindle are generally designed motor constant torque, and the highest speed of the motor power is geometric relation and the relationship between voltage, voltage and power linear increase with the increase of the electric spindle speed.Maintain basic constant current, because the relationship between the torque and current is linear relationship, so that the pattern of motorized spindle for constant torque motor.Grinding general balance of motorized spindle speed range is small, usually is the highest speed of 80% 100%, while both the highest xu thread speed of grinding wheel, therefore generally cannot use when using high speed small grinding wheel with low speed big wheel, otherwise it will lead to big for low power is not enough grinding wheel grinding effect and efficiency is lower, because the big wheel itself weight, high speed motorized spindle bearing capacity can't meet the requirements of main shaft bearing life resulted from the reduced sharply, precision greatly shorten service life.Motorized spindle electric spindle and milling machining center in design usually has permanently match the torque and constant power, in order to satisfy the wide speed range of the cutting, need high torque at low speed heavy cutting, high speed needs a certain power of finishing cut, so the motor system and grinding motorized spindle has great different.
