key characteristics   

High precision: Laser interferometer that is high-precision inspection equipment has been adopted to performance precise inspection over key geometrical motion through assembly process and make compensation for air temperature, material temperature, humidity, air pressure in real environment, so as to keep 1.1ppm system precision and ensure high drilling precision for the entire machine.
Based on the multidisciplinary characteristic of PCB driller, PCB driller digital sample development system has been set up so that design and simulation of multidisciplinary combination is achieved. Product function and performance has been inspected and corrected so that product performance can live up to the performance as it is designed, in which all the conflicts between disciplines can be resolved and the best combination comes true. Thus, product development cycle is largely shortened, product quality improved and system performance enhanced. 
Z axis adopts linear motor drive with high performance which improves production capacity greatly.
High-speed linear motor is adopted as X, Y axis direct drive so that the Positioning speed is up to 80m/min, and high precision positioning is achieved.
The independent fast drilling function ensures the stability of fast drilling and effectively increases production capacity.
All base component of the machine adopts “Taishanqing” or “Jinanqing” granite.
Quick insert change function, suitable for micro-hole drilling.
Contact broken tool checking system: real-time checking of broken tool
Blind hold drilling: intensive controlled precision ±25μm
