Shuochao CNC has completed the manufacturing of one TX125300 CNC gantry boring and milling machine. Adopting a box-in-box gantry structure, the machine features an effective X-axis travel of 12.5 meters and Y-axis travel of 30 meters. It is equipped with a large hydrostatic CNC indexing rotary table with a load capacity of 400 tons, a table surface diameter of 10 meters and a swing diameter of 12.5 meters.

Developed to meet the requirements for boring, milling and rotary indexing machining of large and heavy workpieces, this machine represents one of Shuochao CNC’s manufacturing cases of large-size gantry boring and milling machines.

Main Features of TX125300 Gantry Boring & Milling Machine

For a gantry boring and milling machine with a 30-meter-class extra-long travel, the machining range, structural form and load capacity of the equipment must be matched as an integrated system. The TX125300 adopts a box-in-box structure with an effective X-axis travel of 12.5 meters and Y-axis travel of 30 meters, offering ample machining space for large workpieces.

During the structural design phase, Shuochao CNC configures the gantry, beam, ram and motion system in accordance with the machine’s machining range and application requirements, ensuring all primary structures meet the machining demands of this extra-large-size machine tool.

Box-in-Box Structure Suitable for Large-size Gantry Boring & Milling Machines

The TX125300 gantry boring and milling machine adopts a box-in-box structure.

The box-in-box structure is a common structural form for large gantry boring and milling machines. Its core characteristic lies in the combination of internal moving structures and the main external frame to integrally arrange key components such as beams and rams.

For this 30-meter-class long-travel machine, the box-in-box structure, combined with the overall machine dimensions and machining travel, provides a solid structural foundation for machining large workpieces.

In the manufacturing of large gantry boring and milling machines, Shuochao CNC designs machine structures tailored to customers’ workpiece dimensions, weights and machining processes, so that equipment specifications match actual production requirements.

Equipped with 400-ton Hydrostatic CNC Indexing Rotary Table

The TX125300 gantry boring and milling machine is fitted with a large hydrostatic CNC indexing rotary table.

This rotary table has a load capacity of 400 tons, a table surface diameter of 10 meters and a swing diameter of 12.5 meters, satisfying the fixturing and rotary machining needs of large heavy workpieces.

For large workpieces, the table dimensions and load capacity need to match the overall machining range of the machine tool. The 10-meter-diameter tabletop provides generous workpiece mounting space, while the 400-ton load capacity is configured for the machining requirements of large and heavy workpieces.

The hydrostatic CNC indexing rotary table also supports CNC indexing function. It can rotate and position workpieces at specified angles according to machining procedures, enabling multi-angle machining of large workpieces.

12.5 m × 30 m Machining Range for Large Workpiece Machining

The TX125300 gantry boring and milling machine has an effective X-axis travel of 12.5 meters and Y-axis travel of 30 meters.

The long-travel design covers a broader workpiece machining area. For large structural parts, heavy mechanical components and other extra-large-size workpieces, equipment configuration can be customized based on specific machining processes.

In real-world projects, large workpieces vary greatly in dimension, weight and machining position. Therefore, large gantry boring and milling machines usually require customized specifications and functional configurations for individual workpieces.

Fitted with the large-size rotary table, the TX125300 not only delivers an extensive linear machining range but also completes multi-angle machining by leveraging the rotary and indexing functions of the table.
