Product Series:Air Bearing Spindle

Product Number:DQF-350

This product is a ultra high-speed air bearing spindle for drillingmachine, with the maximum speed up to 350,000rpm. It is mainly used for PCBdrilling.

Performance characteristics
1.high precision: PCB industry spindle static rotation accuracy ≤ 0.002mm, dynamic accuracy ≤ 0.006mm (factory standard), with unparalleled high-precision characteristics, to achieve higher precision drilling capacity.
2.high power, high torque output: combined with the drive performance characteristics, the use of built-in motor design, built-in three-phase variable frequency asynchronous motor, output power, torque, processing capacity increased significantly.
3.high configuration: the industry are spindle spindle automatic tool change function, but also with a motor temperature sensor.
4.high energy: to ensure the performance of the premise, to optimize the minimum air consumption, reduce the cost of end-use customers.
5.compatibility, good scalability: PCB industry with a good spindle compatibility, can be widely used in the circuit board industry, a variety of drilling machine. Can also be customized according to customer needs,
6.low failure rate: innovative and stable design, so that the stability of the spindle is significantly better than peer products, one year under the average probability of less than 3%, the second year on average less than 10%.
7.low maintenance rate: pouring broach structure design, broach body by the axle of polymer materials, high stability of the disc spring and high nitrogen stainless steel material chuck combination, spindle knife life of up to 500,000 Times.
