CNC Angle Iron Punching and Cutting Machine | CNC Angle Steel Flange Production Line

Product Description

CNC Angle Iron Punching and Cutting Machine

The JACK-AIVA CNC Angle Iron Punching and Cutting Machine automates the preparation of steel angle components for HVAC duct flanges. It combines servo-controlled feeding, hydraulic hole punching and automatic cut-to-length in one machine.

Also described as a CNC Angle Steel Flange Production Line, the equipment processes equal-leg steel angles within the specified range of L30 × 30 × 3 to L50 × 50 × 5 mm. The standard material thickness range is 3–5 mm.

Operators enter the required processing length, hole spacing and quantity through the control system. The PLC and servo drive coordinate material positioning, punching and cutting, reducing repeated manual measuring and handling between operations.

The specified tooling includes 9 × 13 mm bolt-hole dies and Φ4.2 mm rivet-hole dies. Tooling for 11 × 15 mm bolt holes can be prepared as a custom configuration.

The machine has a specified feeding speed of 12 m/min and a length tolerance of ±0.5 mm at a workpiece length of 2,000 mm. Finished components are ready for subsequent flange-frame assembly according to the customer’s drawings.

Production Process

Angle Loading and Positioning → Servo Feeding → Bolt-Hole and Rivet-Hole Punching → Automatic Cut-to-Length → Finished Component Collection

The operator sets the required length, hole spacing and quantity before starting the production cycle.

The servo feeding system positions the angle steel for punching and cutting. Hole patterns are produced using the installed dies, and the material is cut into individual flange components.

Actual output depends on component length, hole quantity, hole spacing and the punching and cutting cycle times.

Key Features

Technical Parameters

The specified 12 m/min is the material feeding speed. Completed-part output varies with the programmed hole pattern and cutting cycle.

The stated ±0.5 mm tolerance applies to workpiece length at 2,000 mm; it is not a separate specification for hole-position accuracy.

Bolt-Hole and Rivet-Hole Punching

The machine is configured to process the two hole types commonly required in angle-steel duct flange components.

Bolt Holes

The standard configuration includes one set of dies for 9 × 13 mm bolt holes. These holes provide connection points for assembling matching flange components according to the duct joint design.

Dies for 11 × 15 mm bolt holes can be prepared when required by the customer’s drawing.

Rivet Holes

The specified rivet-hole tooling produces Φ4.2 mm holes for the flange-to-duct attachment arrangement. One rivet-hole die set with five punch pins is included in the documented configuration.

Hole spacing and the required processing quantity are entered through the control system. Tooling selection should match the angle dimensions, material thickness and hole layout.

PLC Control and Servo Feeding

The PLC control system coordinates feeding, punching and cutting according to the entered production settings.

The servo motor drives material feeding and positioning. Operators can set the required processing length, hole spacing and quantity for each production job.

The system also includes self-diagnosis and production data statistics to support machine operation and production monitoring.

Machine Configuration

Applications

The machine is suitable for preparing punched and cut steel angle components for:

• Rectangular HVAC duct flange frames.
• Ventilation duct connection assemblies.
• Angle-steel mounting and connection members.
• Equipment supports and brackets within the specified processing capacity.
• Custom angle components requiring repeated hole patterns and cut lengths.

The main configuration is specified for equal-leg angle steel. Requests involving flat bar, U-channel or tube profiles require a separate review of tooling, material support and processing capacity.

Why Choose This Machine?

Combined Punching and Cutting

Feeding, hole punching and cutting are coordinated in one production sequence, reducing transfers between separate machines.

Programmable Production Settings

Processing length, hole spacing and quantity can be entered through the control system for different flange component requirements.

Tooling for Two Hole Types

The specified configuration covers both bolt holes and rivet holes used in angle-steel duct flange fabrication.

Defined Length Tolerance

The documented length tolerance is ±0.5 mm at 2,000 mm, providing a clear reference for discussing component requirements and acceptance criteria.

Custom Hole Requirements

Alternative punching dies can be prepared according to the required hole dimensions and approved workpiece drawings.

Information Required for Quotation

Send your angle profile and hole-layout drawings to JACK-AIVA for a suitable machine configuration and quotation.

FAQ

What angle sizes can the machine process?

The specified range is L30 × 30 × 3 to L50 × 50 × 5 mm equal-leg steel angle, with material thicknesses of 3–5 mm. The exact angle specification and material grade should be confirmed during machine selection.

Does the machine perform both punching and cutting?

Yes. The machine combines servo feeding, hydraulic punching and automatic cut-to-length under PLC control.

What hole sizes are included?

The documented configuration includes 9 × 13 mm bolt-hole tooling and Φ4.2 mm rivet-hole tooling. Dies for 11 × 15 mm bolt holes can be prepared as a custom configuration.

Can the hole spacing be changed?

Yes. Hole spacing is entered through the control system. The complete hole layout should be checked against the tooling and workpiece dimensions.

What is the feeding speed?

The specified feeding speed is 12 m/min. Finished-part output depends on the number of holes, component length and punching and cutting cycles.

What is the length tolerance?

The documented length tolerance is ±0.5 mm at a workpiece length of 2,000 mm. Requirements at other lengths should be confirmed in the technical agreement.

Can it process U-channels, flat bar or tubes?

These profiles can be evaluated as custom processing requirements. Suitable tooling, feeding support and capacity must be confirmed for each profile.

Does the machine produce an assembled flange frame?

It produces punched and cut angle components. These components proceed to flange-frame assembly according to the required joint design.
