This spindle is a high-speed air bearing motorized spindle, which iswell-designed for high-precision, high-speed and efficient drilling in the PCBindustry. It is designed with a big power, so its torque is strong, solid andendurable to ensure that the spindle has the strong capacity to drill bigholes. It is suitable for machining multi-layer boards, high-density boards,super-hard boards, ceramic boards and others.
This spindle is a motorized spindle with the built-in motor. It isbuilt-in with a three-phase variable frequency asynchronous efficient motor,with the maximum speed up to 160,000rpm. With the speed measuring function, ithas a drilling diameter of φ0.2～φ6.35mm.
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. It can also be customized according to customer needs.
6.Low failure rate: Owing to the innovative and stable design, the spindle’s stability is greatly superior to similar products; the averaged fault rate is less than 3% in the 1st year and less than 10% in the 2nd year.
7.Low maintenance rate: It adopts the pour-out tension structural design, the tension mechanism is composed by the combination the shaft handle made of high polymer materials, the disc spring with high stability and the chuck made of high-nitrogen stainless steel. The service lift of the spindle tool is up to 500,000 times.
8.High bearing capacity and rigidity: The front structure of the flying disc of the shaft core substantially increases the radial bearing capacity and rigidity of the spindle.
