Large Strange Boring Machine

On-site boring for steel, copper, stainless steel (stern and rudder shafts): Straight holes, step holes, grooves, chamfers, end faces. Modular design allows horizontal or vertical installation based on site conditions. Alloy steel bar with chrome-plated surface, heat-treated for high strength and rust resistance. KK bronze worm wheel spindle box ensures rigidity and durability. Elastic sleeves on spindle box, end supports, and center support eliminate gaps. Flexible installation of spindle box (power head) at any position on boring bar. Imported double-row self-aligning cylindrical roller bearings on front and rear main supports. Boring bar holder and flat cutter holder are detachable for easy assembly and disassembly. Adjustable center support facilitates installation in deep holes. Features high precision, reliable components for stability, durability, and dynamic responsiveness. Lightweight, powerful, high rigidity, high precision structure with constant torque stepless speed regulation between all speeds. Capable of cutting up to 8mm depth during rough machining; achieves high surface roughness of Ra3.2 during fine machining.
