Floor-type boring and milling machines, as key equipment in heavy machinery manufacturing, are widely used in the processing of large parts in industries such as energy, shipbuilding, metallurgy, and rail transportation due to their large stroke, high rigidity, and strong load-bearing capacity. With advancements in manufacturing technology, these machine tools have developed significant differences in structural form, functional configuration, and processing capabilities. Users need to differentiate between these differences based on their actual process requirements when selecting a model.
From a structural layout perspective, there are two common types: fixed-table and moving-table. Fixed-table machines primarily use a column that moves longitudinally along the bed and a spindle head that feeds vertically. They have strong load-bearing capacity and are suitable for processing heavy workpieces that are difficult to move. Moving-table machines, on the other hand, rely on the table moving laterally or longitudinally along guide rails for positioning, facilitating workpiece position adjustments during a single setup and improving multi-faceted processing efficiency.
In terms of the number of motion axes, standard models are mostly three-axis (X, Y, Z), capable of completing basic operations such as boring and milling. Multi-axis models add rotary axes (such as A and C axes or a rotary table), enabling machining of complex spatial angles and meeting the machining requirements of complex curved surfaces and inclined holes. These models are mostly used in aerospace, mold making, and other fields with high requirements for geometric accuracy and multi-directional machining capabilities.
Based on the spindle drive method, mechanically driven spindles rely on gearboxes to achieve multiple speed levels, providing stable torque output and suitable for heavy cutting conditions; electric spindles, on the other hand, have stepless speed regulation and rapid start/stop characteristics, which are beneficial for precision machining and high-speed cutting. In addition, some models are equipped with CNC rotary tables or exchange systems, which can shorten auxiliary time and improve continuous production capacity.
Overall, the differences between floor-type boring and milling machines lie in structural rigidity, axis configuration, drive type, and extended functions. These differences directly affect the applicability and machining efficiency of the equipment. A reasonable assessment of workpiece characteristics and process routes is essential to ensure that the selected model matches actual production needs and maximizes the value of the equipment.
