Deep Hole Drilling Machine For Processing The Irregular Hole
The machine is capable of drilling, push boring, pull boring, and trepanning functions, and can process irregularly shaped holes
Description
BTA drilling: Cutting oil is supplied to the tool through the gap between the oil guide, tool holder and hole wall, and chips are discharged through the inner hole of the tool holder.
Push boring: Cutting oil is supplied to the tool through the gap between the oil guide, tool holder and hole wall, and chips are discharged through the workpiece's bottom hole. During machining, the tool moves towards the headstock.
Pull boring: The tool holder passes through the workpiece's inner hole to the front end of the headstock spindle, where the tool is then installed. During machining, the tool moves away from the headstock. Cutting oil is supplied to the tool through the gap between the oil guide, tool holder and hole wall, and chips are discharged through the workpiece's inner hole towards the headstock.
Trepanning : Internal oil supply, external chip removal. Cutting oil is supplied to the tool through the inner hole of the drilling bar, and chips are discharged through the gap between the outer wall of the drill bar and the hole.
