Drilling motor spindle DQF-300D

machiningmotorizedwater-cooled

This spindle is a motorized spindle with built-in motor. It is built-inwith a three-phase variable frequency asynchronous efficient motor, with themaximum speed up to 300,000rpm.It is especially suitable for drilling small holes (φ2～0.05mm). 1.High-precision: The spindle for PCB industry has the static rotary precision ≤ 0.002mm and dynamic precision ≤ 0.006mm (delivery standard), has the characteristic of incomparable high precision, and can achieve higher drilling CPK values. 2.High power and large torque output: Combined with the performance characteristics of driver, by adopting the design of embedded motor and the built-in three-phase variable-frequency asynchronous high-efficiency motor, it improves the output power and torque within the range of speed required by machining, and substantially enhances the machining capacity. 3.High configuration: The spindles for the industry all have the automatic tool changing function with the service life of the tension mechanism up to 2,000,000 times, and also have the protective functions for the temperature sensor of motor, the speed sensor of shaft core, etc. The ball bearings adopt the international famous brands. 4.High energy saving: On the premise of guaranteeing the performance, the gas consumption of dust-proof sealing is optimized to the minimum, in order to save the usage cost of the end users. 5.Good compatibility and good expansibility: The spindles for PCB industry have good compatibility, and can be widely used for various drilling machines and forming machines in the circuit board industry.
