Bending Quality at Its Best

For electrical cabinets, doors, frames and stainless furniture, bending accuracy directly affects fit, appearance and welding time. By working with a professional CNC press brake manufacturer, you get machines that control ram stroke, pressure and backgauge position with high precision. Proper crowning, quality tooling and stable mechanics help you maintain the same bending angle and flange length across large batches, reducing manual correction and hidden cost in production.

Main Systems of the CNC Press Brake from Our Factory

Our CNC press brake machines consume only 40%–60% energy compared to traditional hydraulic press brakes, operate at noise levels as low as 75 dB, and cut maintenance costs by up to 50% (no need for hydraulic oil or frequent filter replacement). With 4–8 axis control, digital programming, intelligent compensation, and an intuitive human–machine interface, they adapt easily to small-batch customized production and large-scale efficient processing. The built-in fault self-diagnosis ensures quick troubleshooting and stable, long-term operation.

01

Frame & Ram

As a CNC press brake manufacturer, we design the frame and ram with high-strength steel, welded and stress-relieved to minimize deformation. Precision guides keep the ram moving smoothly, maintaining parallelism along the entire bending length for consistent angles and straightness.

02

Backgauge System

The servo-driven backgauge system positions sheets accurately for each bend. Multiple fingers and optional axes allow you to handle short flanges, small parts and complex bending sequences, greatly reducing manual trial and error in your workshop.

03

Tooling & Clamping

We supply matched punches and dies together with the machine, based on your typical materials and thicknesses. Quick clamping systems shorten tool changes, enabling fast switching between different jobs and helping distributors or OEM clients build complete solutions around our press brakes.

Laser Hands Protection Device (Optional)

04

Hydraulic / Servo Drive

Depending on the model, the ram is powered by a robust hydraulic system or an energy-saving servo drive. Both options are engineered for smooth speed transitions, stable pressure and low noise, ensuring reliable operation for full-shift production.

05

CNC Control Panel

The CNC control provides graphic programming, angle calculation and step-by-step bend sequence planning. Operators can easily create, save and modify programs, while diagnostic functions support quick troubleshooting and reduce downtime.

06

Safety & Maintenance

Light curtains, foot pedals with safety interlock, side guards and emergency stops are standard on our CNC press brakes. At the same time, the layout of doors and covers allows easy access to maintenance points, making daily inspection efficient and safe.

FAQ About Working with a CNC Press Brake Manufacturer

FAQ

Are you a trading company or a real CNC press brake manufacturer?

Are you a trading company or a real CNC press brake manufacturer?
We are a real CNC press brake manufacturer in China, not a trading company. We design, assemble and test our press brakes in our own factory, which gives us better control over quality and delivery time.

What information do you need to recommend a suitable CNC press brake machine?

Please share your material type, thickness range, maximum bending length and typical part drawings. As a manufacturer, we use this information to suggest the correct tonnage, configuration and tooling.

Can you supply tooling together with the press brake?

Yes. We can supply standard punches and dies, as well as special tooling if required. This makes it easier for you to start production immediately after installation.

Do you support OEM projects for CNC press brake machines?

Yes. As a CNC press brake manufacturer, we can customize machine color, logo, nameplates and documents for OEM partners, and adjust configurations to fit your local standards.

How long does it take to install and train operators?

For most models, basic installation and training can be completed in a short time, depending on your local conditions. We provide manuals, videos and online guidance, and can arrange on-site service for key projects.

What is the typical service life of your CNC press brakes?

With proper maintenance, our press brakes can serve in industrial environments for many years. We design the frame, hydraulic/servo system and backgauge components to withstand continuous production.

Do you provide after-sales support and spare parts?

Yes. We keep key spare parts in stock and offer remote technical support. For urgent issues, we can cooperate with your local technicians or arrange our engineers to visit if necessary.

Can you also supply other sheet metal machines besides CNC press brakes?

Yes. Besides being a CNC press brake manufacturer, we also produce CNC panel benders, turret punch presses, laser cutting machines and automatic sheet metal production lines, which can be combined into a complete solution for your factory.

What is the difference between a Hydraulic Press Brake and a CNC Press Brake?

A hydraulic press brake relies on hydraulic cylinders to apply bending force, offering strong tonnage for thick materials but requiring more maintenance.
A CNC press brake, on the other hand, combines servo motors and CNC control for greater precision, energy efficiency, lower noise, and easy programming. CNC press brakes are preferred for complex bending tasks, small-batch customization, and high-precision sheet metal production.

How do I choose the right Press Brake Machine for my business?

When choosing a press brake machine, consider:

Material thickness & length (determine tonnage and worktable size).
Production type (large-scale hydraulic press brake vs. flexible CNC press brake).
Automation needs (CNC system, servo drive, backgauge, crowning).
Budget & maintenance (CNC press brakes save 30–50% energy and reduce oil maintenance).
This ensures you select the most cost-effective solution for your sheet metal bending applications.

What industries use CNC Press Brakes?

CNC press brakes are widely used in industries requiring precision sheet metal bending, such as:

Electrical cabinets and enclosures
Automotive and aerospace parts
Appliances and furniture sheet metal
Construction and HVAC equipment
Custom fabrication workshops

How to maintain a Press Brake Machine for long-term performance?

Proper maintenance of a press brake machine ensures accuracy and durability. Key practices include:

Regular lubrication of moving parts
Checking backgauge and grating ruler alignment
Cleaning hydraulic/electrical systems (for hydraulic press brakes)
Using proper bending tools and dies
Running self-diagnosis and CNC system checks
With regular care, CNC and hydraulic press brakes can deliver stable, long-term bending performance.

What materials can the press brake bend?

Commonly, it bends carbon steel, galvanized steel, stainless steel and aluminum sheets within the specified thickness range. Special materials can be evaluated case by case.

What is the difference between hydraulic and servo press brakes?

Hydraulic press brakes are robust and widely used for general bending. Servo press brakes offer lower energy consumption, higher positioning accuracy and quieter operation, suitable for high-precision or energy-sensitive applications.

Can the machine store programs for repeat orders?

Yes. The CNC control can store a large number of bending programs. Operators can quickly recall them when repeating the same parts, saving setup time.
