1 This machine抯 base part use natural "jinanqing"granite, a kind of granite has a history of more than millions of years and yields little to the outside environment changes such as changes in temperature and humidity. As it is better than other machine bed in precision rigidity and stability, it enjoys such advantages as high precision in processing, gallant appearance, no distortion under force, and no yield to slight shake. 2 with the CBD contact moving tool-checking system, an automatic, quick, and stable drilling is possible 3 The machine抯 three-dimension transmitting and leading system adopt such precise self-lubricating linear lead and precision lead screws, both of worldwide well-known brands and have little friction. They can ensure such qualities as flexibility in fast movement, high tenacity, and stable precision after long operation. These qualities ensure machine抯 good performance and reliability after long operation. 4 The joint between the motor axis and lead-screw axis is a professional metallic spindle from KTR, Germany. It is tenacious as well as quick in clockwise and anticlockwise move, and has wide transmission torque, leaving no clearance in anticlockwise movement. With the bolt-locked system, it boosts easy fixing and convenient repairing 5 Using pneumatic position-clamping structure by SMC Company, Japan and the automatic clamping structure instead of the dowel, a precise and quick circuit board position and clamping can be made. 6 By using the professional high-speed transducer of Sieb&Meyer Company (Germany) and alternating servo electric machine from BAUTZ Company (Germany), the machine抯 moving speed is 50m/h, and its position precision is 0.005mm with 0.0025mm as its reiteration precision. 7 By using the Heidenhain Company抯 enclosed raster as its closed-loop feedback system, its distinguishing rate reached 0.001mm with a feedback speed more than 120m/min. This machine抯 hole-drilling precision and quick drilling is improved. 8 with the Italian GIMATIC manipulator, the machine can pick and set the tool flexibly and reliability, greatly improved working efficiency.
