|Deep Hole Pull Boring Machine Basic Function
The deep hole pulling boring machine can work on
inner hole pull-boring, expand and
rolling-pressing. When pull boring machine work,
workpiece will static(not rotary), cutter rotary
and infeeding, the cutting liquid will enter to
cutting area through oil provide device, cooling
and lubricating the cutting area and bring the
chips away. When deep hole pull boring works, it
adopts auto chips removal method, the chips will
be discharged thorugh the front chips box.
Deep Hole Pull Boring Machine Processing Accuracy
Rough boring: hole diameter accuracy IT9-10.
Surface roughness: Ra6.3.
Precision boring: hole diameter accuracy IT8-9.
Surface roughness: Ra3.2.
Rolling-pressing: hole diameter accuracy IT8-9.
Surface roughness: Ra0.2.
Holes straightness: Less than 0.15/1000mm.
Holes exit screwness: Less than 1/1000mm.
Deep Hole Pull Boring Machine Processing
Deep hole pull boring machine processing
Cutting speed: according to cutters' struction,
cutters'material and workpiece material, normally
speed is 50-150m/min.
Infeed speed: according the requirement, normally
When boring, the Max.processing finish allowance:
according the cutter's struction, cutters'material
and workpiece condition, single side processing
amount less than 10mm.
