CNC tube sheetdrilling Machine
This equipment is mainlycomposed of bed and vertical slide, gantry and horizontal slide, the verticalram drilling power head, chip conveyor, hydraulic systems, cooling systems,centralized lubrication systems, electrical systems, pneumatic systems andother components.
A. Feature
a)Mainly used to drill flange,heat-exchanger ,tube-sheet and the inner & outer ring of big slewingbearing ring .
b)Precision spindle , highspeed drilling with slight milling function.
c)Directly transfer ofCAD/CAM, automation and high precision can be realized.
d)Spindle box of the machineare adopted cast iron formed resin bonded sand process and reasonable layout ofribs to provide good stiffness and steadiness.
e)The bed and worktable of themachine are adopted cast iron formed resin bonded sand process and reasonablelayout of ribs to provide good stiffness .Good rigidity ,and steady .
f)The heavy spindle group withhigh quality adopted belt roller provides ultra-large torque output capacity.
