1.Product Overviews

1)This machine can drill,bore,roll and trepanning inner holes.

2)when producing,the workpiece is rotating,cutter feeding,then the cutting fluid goes into cutting area to cool and lubricate the cutting area ,and take out clastics

3)When boring,the machine will discharge cutting fluid and chips forward.

4)Rough boring:hole dia precision is IT9-10.surface roughness is Ra6.3um

Refined boring:hole dia precision is IT8-9.surface roughness is Ra3.2um

Rolling :hole dia precision is IT8-9.surface roughness is Ra0.4um

Outlet angle of the hole:less than 0.3/1000mm

Straightness of the hole:less than 0.15/1000mm
