1.This machine is composed of transverse conveyor, rotating loadin system, infeed conveyor, CNC Infeed carriage, CNC drilling Unit,marking unit, unloading conveyor, as well as hydraulic, electrical and pneumatic systems etc.
2.There are three groups of drilling heads on each side of drilling unit,which can install three kinds of drills with different diameters.
3.CNC drilling head uses two Linear Motion Rolling Guides,driven by AC servo motor and precision ballscrew.Drilling spindle is Taiwanprecision drilling spindle (inner cooling)with disk spring automatic broach mechanism,hydraulic crimpling cylinders.It is very convenientto change the shank.
4.Marking unit adopts closed frame with good rigidity.Marking stadia can be set at will.
5.CNC infeed carriage isdriven by servo motor,The photoelectric encoder feeds back the information.Closed loop control to ensure highpositiong precision.
6.Hydraulic system is mainly used to complete clamping workpiece,crimpling of drilling spindles,hydraulic balance of slipway of drillinghead and marking.
7.Control system consists of upper computer,CNC system,servo motor,PLC and outside detection swith etc.Processing program can be generated automatically as long as operator inputs the dimensions of workpiece.It can also accept certain processing program which is made from special software.Theprogram can be stored ,selected,displayed and communicated as per the workpiece No.
