GM-SB-18CNC Full-Auto Numerical Control Single-Head Bending Machine

Technical Specifications

Features & Benefits

CNC Three-Axis Servo Control

The Y, B, and C axes use closed-loop servo motor control for tube feeding, rotation, and bending. This coordinated motion supports repeatable bending operations and helps maintain consistency across production batches.

Bending Precision and Springback Compensation

The machine offers a specified bending precision of ±0.10°. Its springback compensation function allows operators to adjust bending programs according to material behavior, helping improve bending angle consistency.

Touchscreen Programming and Data Storage

The VDU touchscreen allows operators to input, store, and display bending data and operating sequences. Saved programs simplify repeated jobs and reduce the need to enter the same settings again.

Automatic Lubrication System

The machine includes an automatic lubrication function for designated moving components. This supports routine operation and reduces manual lubrication work, while regular maintenance remains necessary.

Error Diagnosis and Safety Protection

The CNC control system includes error self-diagnosis alarms and safety protection functions. These features help operators identify abnormal conditions and support safer machine operation.

Power-Failure Memory Storage

The machine supports bending data storage after power failure. This helps preserve programmed settings and reduces the need to re-enter bending data when operation resumes.

Industrial Applications

Automotive Tube Components

The GM-SB-18CNC can support selected small-diameter tube bending applications in automotive component production. Its CNC control system manages feeding, rotation, and bending for repeatable part geometries.

Metal Furniture and Tubular Frames

The machine can be considered for producing bent tube components used in metal furniture and support frames. Final suitability depends on tube dimensions, material properties, and tooling requirements.

Small-Diameter Metal Tube Processing

The machine is designed for tube bending applications within its specified capacity. CNC programming supports components requiring controlled bend angles and multiple bending positions.

Industrial Metal Fabrication

Metal fabrication workshops can use the GM-SB-18CNC for repeated tube bending tasks. Stored programs allow operators to return to previous bending configurations when production requirements change.

Frequently Asked Questions

What is the maximum bending capacity of the GM-SB-18CNC?

The manufacturer lists a maximum bending capacity of Φ18 × 2 mm. Actual suitability depends on tube material, wall thickness, and bending requirements.

What is the bending precision of this CNC pipe bending machine?

The listed bending precision is ±0.10°. The machine also supports springback compensation for bending program adjustments.

Can the machine bend stainless steel and aluminum tubes?

Material compatibility depends on tube dimensions, tooling, and bending radius. Contact GMACC with material details before selecting the machine.

Can operators save different bending programs?

Yes. The touchscreen control system supports bending data entry, storage, and display. This helps operators reuse settings for repeat production.

What information is needed for a machine quotation?

Provide the tube material, outside diameter, wall thickness, bending radius, and workpiece drawing. GMACC can review the application and discuss suitable configurations.
