Pipe bending machines are utilized across a wide range of industries, including interior renovation, automotive manufacturing, electric power construction, railway building, boiler and bridge fabrication, shipbuilding, and pipeline installation and retrofitting. Proper operation ensures worker safety and significantly extends the machine's service life. The bending process not only prevents collisions between the carriage and the pressure die—ensuring the successful completion of the final bend—but also minimizes material waste at the clamping end and reduces production costs.

The bending head can move laterally along guide rails; this adjustment is essential for aligning the bending die's groove with the machine's centerline after a die change. This method is simpler than adjusting the machine's centerline by moving the bed's guide rails or tailstock. During the bending process, the carriage acts as a load and is pulled forward by the pipe; to improve bending quality, minimize wall thinning in the bend zone, and reduce springback, a booster mechanism is incorporated. During bending, the pressure die not only clamps the pipe but is also pushed forward by the booster force, creating a lateral thrust that assists the bending action. The bending arm and main bending spindle are integrated into a single unit, the bending die shaft is interchangeable, and the clamp die moves vertically; this design not only enhances structural integrity and mechanical strength but also simplifies the overall structure and electrical circuitry.

The carriage, which handles the linear feed motion (DBB), is pulled forward by the pipe during the bending process. This eliminates the need for "positive thrust," thereby removing issues regarding synchronization between the carriage and bending speed, eliminating the DC motor negative feedback system previously required for positive thrust, and simplifying the electrical wiring. However, since positive thrust is beneficial—and often essential—for bending, particularly with large-diameter pipes, the VB pipe bending machine incorporates a booster mechanism.
