Fully automatic CNC large-size tee beveling machine

This equipment is specifically designed for groove processing of three large-diameter thick-walled tees (equal-diameter and reducing tees) end faces. Compared to traditional flame cutting, hand-cranked groove machines, and ordinary bevel equipment, its core advantages are as follows:

一,High machining precision and stable welding quality

• Servo + CNC system control, combined with hydraulic automatic centering and clamping, solves deviations caused by excessive self-weight of the large tee, eccentricity of clamping, and ellipsalism, ensuring verticality of the end face and concentricity of the pipe mouth.
• The groove angle, blunt edge, and groove depth are CNC adjustable, with minimal angle errors; Cold milling processes produce a smooth groove surface without oxide layers or burrs, with good roughness, requiring no heavy manual grinding, greatly reducing welding defects and rework rates.
• Mass production ensures high consistency in groove dimensions for each tee, suitable for high-pressure fittings in petrochemical, power, and pressure vessels.

二,High degree of automation, reducing reliance on manual labor

• A single clamping can complete multiple pipe ends for three-way pipe ends. The equipment automatically positions, clamps, feeds, and reels the tool, eliminating the need for repeated alignment or manual tool cranking. No skilled craftsmen are needed; ordinary workers can operate it with simple training.
• Input pipe diameter, wall thickness, groove angle, and blunt edge parameters; the system automatically generates machining trajectories without manual programming; The machining equipment operates automatically, allowing one person to manage multiple machines, saving labor costs.
• Suitable for large-size and heavy-duty tee workpieces, equipped with load-bearing brackets for easy lifting and loading, and convenient clamping and positioning of heavy workpieces.

三, Strong adaptability, multi-purpose device

• Can process large-diameter thick-walled carbon steel, alloy steel, and stainless steel tees; Compatible with equal-diameter tees and reducing tees; for different pipe diameters and wall thicknesses, only parameters need to be modified, eliminating the need for frequent fixture changes.
• Supports various groove styles such as V-shape, U-shape, double V, and J-type, meeting different welding process requirements for high-pressure and thick-walled pipe fittings. Some models can simultaneously process external bevels, inner grooves, and end face leveling.

四,Improved production efficiency, suitable for batch pipe fitting prefabrication

• Cold cutting forming: compared to traditional flame cutting + grinding processes, it eliminates the need for post-cutting grinding and cleaning, greatly improving overall processing efficiency; Large tees require no secondary transfer or clamping, reducing process waiting time.
• Heavy-duty reinforced body design suitable for long-term continuous batch production, excellent equipment stability, suitable for large-scale prefabrication of tees in pipe fittings factories.

五,Safety and Loss Advantages

• Purely mechanical cold cutting, flameless hot working, prevents pipe mouth thermal deformation and material hardening, does not damage the metallographic structure of the tee base material, and ensures the mechanical properties of pipe fittings.
• Enclosed protective structure with concentrated discharge of iron filings, improving workshop working environment; Reduces safety hazards in flame operations.

六,Easy integration into automated production lines

• Can be integrated with tee forming equipment and flaw detection equipment as part of a pipe fitting prefabrication assembly line; Processing data can be retained for easy order quality traceability, adapting to modern pipe fitting factories.
