As an important branch of heavy metal cutting equipment, floor-type boring and milling machines play an irreplaceable role in energy, shipbuilding, metallurgy, mining machinery, and heavy machine tool manufacturing due to their high rigidity, large stroke, and high functional integration. This equipment is directly mounted on the ground, eliminating the base constraints of traditional boring and milling machines, allowing for more flexible relative movement between the spindle and the worktable. It is particularly suitable for machining large, complex box-shaped, frame-shaped, and shell-shaped parts.
Structurally, a floor-type boring and milling machine consists of a bed, column, spindle head, worktable, and multi-axis feed system. The bed is usually a one-piece cast or welded structure, with internal reinforcing ribs and damping layers to suppress cutting vibration and ensure geometric stability over long-term use. The column moves longitudinally along the bed, and the spindle head is vertically mounted on the column and can slide up and down, forming the Z-axis feed of the spindle; the worktable can move laterally or longitudinally on the bed, achieving precise workpiece alignment and multi-face machining. The combination of the crossbeam and slide enables the machine tool to achieve X, Y, and Z-axis linkage, and can be expanded to four-axis or five-axis machining capabilities with the optional rotary table or angle milling head.
The core advantages of the floor-type boring and milling machine lie in its large machining range and high rigidity. The spindle has ample power to withstand heavy-duty cutting with large depths of cut and high feed rates, meeting the needs for rapid material removal from thick-walled blanks. Simultaneously, the application of a fully closed-loop feedback system and precision linear scales ensures high positioning accuracy, guaranteeing micron-level repeatability even over strokes of several meters. Its modular design allows for configuration of different spindle speeds, torque outputs, and accessories according to workpiece characteristics, such as right-angle milling heads, universal milling heads, and rotary tables, thus covering multiple processes including boring, milling, drilling, tapping, and turning.
In the trend of intelligentization, the new floor-type boring and milling machine integrates online measurement, adaptive control, and data acquisition functions, enabling real-time monitoring of cutting status and automatic parameter optimization, improving machining efficiency and quality stability. As the main equipment for manufacturing large and critical components, floor-type boring and milling machines, with their comprehensive performance of wide range, strong power and high precision, continue to support the autonomy and high-quality development of the heavy equipment manufacturing industry.
