TQC250-2CL
The 2-Spindle CNC Milling Machine for Angle Steel (TQC250-2CL) is a game-changer in structural steel processing, integrating dual-spindle technology to redefine efficiency and precision for angle steel fabrication. It addresses the bottlenecks of single-spindle machines, enabling high-volume production without compromising accuracy—ideal for steel fabricators in construction, tower manufacturing, and industrial framework sectors. Key selling points include 50% reduced processing time vs. single-spindle alternatives, ±0.015mm positioning accuracy, compatibility with 50×50×5mm to 200×200×20mm angle steel, and intelligent CNC control for seamless operation.
The machine’s defining feature is its two independently controlled spindles that operate simultaneously or sequentially based on programming. Each spindle delivers 11 kW of power and features a BT40 tool taper, accommodating milling tools from φ10mm to φ50mm in diameter. This configuration allows for concurrent processing of multiple surfaces or sequential operations without manual intervention, significantly increasing throughput for complex angle steel components.
Equipped with high-resolution servo motors and precision ball screws, the machine achieves ±0.015mm positioning accuracy across all axes. The X-axis travel spans 1500mm, while the Y and Z axes offer 600mm and 500mm respectively, providing ample working envelope for standard angle steel profiles. A specialized angle clamping system with adjustable pressure ensures secure workpiece holding without deformation, maintaining consistent precision even during high-speed milling.
This milling machine handles a wide range of angle steel sizes, from 50×50×5mm up to 200×200×20mm, making it suitable for both light-duty brackets and heavy structural components. The spindle speed ranges from 500 to 6000 rpm with stepless adjustment, allowing optimal cutting parameters for different material thicknesses and steel grades up to 690 MPa tensile strength.
The industrial-grade CNC system features a 15-inch touchscreen HMI with intuitive programming interface, supporting both manual input and CAD file import. Operators can store up to 2000 milling programs, each capable of incorporating multiple tool changes and processing sequences. Real-time monitoring of cutting forces and tool wear triggers automatic feed rate adjustments, preventing tool breakage and ensuring consistent surface finish across production runs.
In transmission tower and communication tower manufacturing, the machine excels at milling connection surfaces, slotting, and contouring angle steel components. Its dual-spindle capability is particularly valuable for processing tower legs and bracing members that require multiple milling operations.
The machine processes angle steel for building frameworks, curtain wall supports, and structural connectors. Its precision ensures proper fit-up during on-site assembly, reducing the need for on-site modification and speeding up construction timelines.
Manufacturers of heavy equipment utilize the machine for fabricating angle steel frames, guide rails, and mounting brackets. The consistent dimensional accuracy ensures interchangeability of components across machinery models.
In wind and solar energy projects, the machine processes angle steel components for turbine supports and panel mounting systems, where precision milling is critical for structural stability and load distribution.
When processing 10mm thick angle steel with φ20mm end mills, the machine achieves a maximum feed rate of 8 m/min per spindle. This allows for completion of typical milling sequences in approximately 40% less time than single-spindle alternatives.
The CNC system includes predefined material databases for common structural steels (ASTM A36, S235, S355) and high-strength low-alloy steels up to 690 MPa. Operators can create custom profiles for specialized materials by adjusting spindle speed, feed rate, and cutting depth parameters.
The automatic tool changer supports up to 16 tools with a tool change time of 3 seconds between tools. This rapid tool exchange minimizes non-productive time during complex milling sequences.
Safety features include interlocked machine guards, emergency stop buttons at multiple stations, and a laser scanning system that pauses operation if an object enters the machining envelope. The control system also monitors spindle load and temperature to prevent overload conditions.
The machine operates on a three-phase power supply with 380V AC voltage, 50Hz frequency, and requires a dedicated 60A circuit. Compressed air at 0.6–0.8MPa is needed for the clamping and tool changing systems.
The equipment is used for the backhoe processing of angle steel by using the principle of common milling.
