Product Series：Air Bearing Spindle

Product Number：DQF-320E

This product is an ultra-high-speed air-bearing spindle with ma rotational speed of 320,000 rpm. The spindle is designed with ultra-light body with automatic tool change function.Equipped with high-performance motor, it only takes 5.2 seconds for rising the speed to 320,000 rpm.Superior performance, while significantly improving the low-speed torque, it is fully upgraded in the aspects of large hole drilling capacity and small hole drilling accuracy.It is a product specially designed for high-precision, high-speed and high-efficiency drilling in the PCB industry.

Features

1. High precision: The dynamic deflection at full speed is <6um, which is especially suitable for high-precision drilling with a diameter of 0.3-0.05mm.

2. High efficiency: The rotational speed can reach 200,000 rpm within 3.4 seconds;

250,000 rpm within 4.1 seconds;

320000rpm within 5.2 seconds;

The efficiency of start and stop is increased by 2.5%.

3. Strong ability to drill large holes: The low-speed torque reaches 0.044Nm, and the 5.0mm tool can continuously process more than 1000 holes (S25000 F0.2 R0.5 3*1.6mm FR4).

4. High thermal stability: The thermal-structure coupling model is established, and the temperature field is deeply optimized to ensure that the spindle temperature rise is ≤3.5℃ (competing product 4℃), the machine sizing is 6um (competitive product 7um), and the average CPK2.447 (competing product 2.44), further improving the drilling accuracy of the machine.
