■Machine usage: For Rifle Broaching of gun barrel

■Machine mainly structure:

■Max job length:1000mm

■Job clamping: hydraulic tailstock,job positioning rest equips coned disc,the tainlstock’s main spindle can be forced out automatically undere the hydraulic system control. Use the chamfering to clamp and positioning the job automatically.

■Machine mainly consist of: machine bed,working table,main spindle box,tail holder rest,job positioning rest,hydraulic tailstock,two sets job supporting rest,linear guide rail,GSK CNC system  

■The machine bed,working table and chambers are cast parts.

Main spindle box Z axis move: adopts servo motor,servo gear reducer,ball screw drive to Z axis,max rapid spped is 4.5m/min,servo motor paramters: 4.7KW、15Nm；The movement is using linear guide rail.

■Main spindle box rotating(C direction): adopts servo motor,servo gear reducer to drive main spindle rotating to C direction,main spindle max rotating speed  10r/min，Servo motor parameters: ：2.8KW、18Nm

■During working,main spindle rotating to C directing,at the same time Z direction moves, Z direction and C direction(the two axis) are interlocked.

■Hydraulic tailstock: Could be manual move in the T slot working table,used for different length jobs clamping,after move to the suitable position,hand lock to the working table,movable guide rail is rolling linear guide rail; The tailstock’s main spindle could be expanded out or contracted in under the hydraulic system control. Used for jobs loosen or fasten.  

■Job positioning rest: equips coned disc,work with the hydraulic tailstock to fasten the job.

■Job supporting rest: two sets,used for job pre positioning.

■Adopts elastic collect to connect the tool holder and main spindle,loosen or lock by hand.
