Single Head Wheelbarrow Pipe Bending Machine GM-76CNC-2A-1S

Overview of the GM-76CNC-2A-1S Single Head Pipe Bending Machine

The GM-76CNC-2A-1S is a single-head numerical control pipe bending machine manufactured by GMACC (HS code 8462219000), designed for industrial clients producing wheelbarrow frames, metal furniture tubing, and automotive exhaust components. The machine combines hydraulic bending with servo-driven feeding and rotation, processing mild steel round tube up to Ø76×4mm and stainless steel up to Ø76×3mm. A 4,000mm through-feed distance accommodates long workpieces, and the maximum bending angle of 190° covers standard bending operations for tubular frames and handles.

Key Features of the GM-76CNC-2A-1S Single Head Pipe Bending Machine

Servo-Driven Feeding and Rotation Axes

The feeding axis (X) and rotation axis (Z) are each driven by a 1.5 kW Mitsubishi servo motor, achieving ±0.10mm positioning precision on the X axis and ±0.10° on the Z axis. Maximum feeding speed is 800mm/sec and maximum rotation speed is 160°/sec, supporting efficient multi-bend programs for wheelbarrow handles and furniture frames.

Hydraulic Bending with Spring-Back Compensation

A 7.5 kW system motor drives a 23L hydraulic pump at a maximum pressure of 16 MPa. The CNC controller includes bending spring-back compensation, error self-diagnosis with alarm, and parameter memory retention after power-off. Maximum bending speed is 30°/sec with ±0.10° angle repeatability.

Industrial Applications of the Single Head Pipe Bending Machine

This machine is suited for business buyers manufacturing wheelbarrow frames and handles, metal furniture (chair and table frames), automotive exhaust pipes, and general tubular components. It processes round, square, and rectangular mild steel profiles, light alloy annealed tube, and solid round or square bar within the capacities listed above. The minimum bending radius of 30mm supports tight-radius bends common in furniture and wheelbarrow construction, while the 350mm standard maximum bending radius covers larger frame components.

FAQ About the GM-76CNC-2A-1S Single Head Pipe Bending Machine

What is the maximum tube diameter this machine can bend?

For mild steel round tube the maximum capacity is Ø76×4mm; for stainless steel it is Ø76×3mm; for light alloy annealed round tube it is Ø76×6mm. Square and rectangular mild steel tube capacities are 60×60×3mm and 65×55×3mm respectively.

Does the machine support mandrel bending for thin-wall tube?

Yes. The machine supports both mandrel and mandrel-less bending. Mandrel retraction stroke is adjustable from 0 to 136mm, and a wiper die can be added as an option for thin-wall stainless steel bending to reduce wrinkling.

What are the packaging and shipping details?

The machine is packaged in an iron frame or wooden case with packaging dimensions of 4800×1200×1350mm and an approximate machine weight of 3.5 tons. The standard shipping port is Shanghai, China, and the minimum order quantity is one piece.
