Drilling motor spindle DQF-200E4.S

machiningmotorizedwater-cooled

Itis mainly applied to high-speed and high-precision machining for drilling inprinted circuit board industry (PCB). Theproduct is a kind of high-speed air bearing electric spindle with the maximumrevolution of 200,000 rpm. Long nose design is adopted for the spindle, andthere is speed measurement function. The optimally designed motor has excellentperformance; the temperature rise of high speed section and slip ratio can bereduced while the low speed torque force is obviously improved. All-roundupgrade is realized in big hole drilling ability and small hole drillingprecision fraction. Itis a kind of product that is elaborately designed for high-precision,high-revolution and high-efficiency drilling in PCB industry. 1.High-performancemotor Powerfullow speed torque force: The low speed torque force reaches as high as 0.18N.m;6.35 mm cutter can perform continuous processing for more than 10,000 holes(S20000 F0.3 R5.0 3*1.6mm FR4), which can easily process various thick plates andhard plates. Excellenthigh speed performance: The maximum revolution is 200,000 rpm; the maximumrevolution can be reached within 3.8S; the slip ratio is as low as 1%; the lowloss (low temperature rise) and quick start and stop function is particularlysuitable to the machining of 0.2-0.3 mm small holes. 2.Shaftsystem design with high stability Prepositionedstructure is adopted for spindle core and flying disc; the radial bearingcapacity and rigidity of spindle is improved; floating structure is adopted forbearing to obviously improve the stability of spindle core. The pour-out typebroach mechanism largely reduces the subsequent maintenance cost and reducesthe maintenance time.
