CNC Press Brake | Hydraulic & Electric Sheet Metal Bending Machines – STON CNC

Yes, we offer a one-stop service: “on-site installation + commissioning + customized training.” Professional engineers will visit the customer’s site to complete production line assembly and equipment integration commissioning to ensure the line reaches its designed capacity. We also provide theoretical and practical training for operators (6-8 days), covering equipment operation, routine maintenance, and troubleshooting. After the training, we provide an operator manual and video tutorials.

Customized services are available. We will optimize the machine structure based on the customer’s workshop space, load capacity, and processing requirements. While ensuring processing accuracy, we adapt the machine to the shop’s existing power and air supply conditions to ensure smooth installation and efficient operation.

We have established a 24-hour global after-sales response mechanism: Customers can submit troubleshooting reports via phone, email, or online customer service, and a preliminary solution will be provided within 1 hour. If remote debugging is required, an engineer will provide video guidance within 2 hours. For hardware repairs, domestic customers will receive a visit within 48 hours, while overseas customers can use authorized service centers or expedited delivery of parts (with installation instructions) to ensure a quick resolution.

All of our standard equipment (flexible bending centers, CNC turret punch presses, press brakes, and punching and shearing machines) comes with a one-year free warranty. For some products with higher system complexity, the warranty period can be extended to 18 months. The warranty covers repair and replacement of quality issues with core components (such as servo motors, CNC systems, and guide rails), as well as free on-site inspections during the warranty period. Please note that equipment failures caused by human error, force majeure (such as floods and earthquakes), or failure to follow the maintenance manual are not covered by the free warranty, but paid repair services are available.

Extended warranties are available, with coverage ranging from 1 to 3 years. These plans are customized based on the equipment type, frequency of use, and customer needs. A one-year extension for a single device costs approximately 3%-5% of the total price, while bulk extensions for multiple devices or fully automated production lines offer a 20% discount. During the extended warranty period, in addition to core component repairs, customers also receive a free annual comprehensive equipment inspection and maintenance service to help them proactively identify potential faults and extend the life of their equipment.

We offer flexible payment options to meet the needs of domestic and international customers: ① Telegraphic Transfer (T/T): 30% prepayment, 70% before equipment leaves the factory; ② Letter of Credit (L/C): We accept irrevocable letters of credit issued by the customer’s partner bank at sight to ensure the security of funds for both parties. All payment methods comply with international trade practices and support mainstream settlement currencies such as the US dollar and the euro.

✔ High Precision CNC Control

Multi-axis synchronized CNC systems ensure accurate angles, stable repeatability, and smooth bending for complex profiles.

✔ Servo Technology for Smooth Bending

Hydraulic servo or pure-electric drive provides fast response, quiet operation, and long-term mechanical stability.

✔ Industrial-Grade Machine Frame

High-rigidity, finite-element-analyzed frames minimize deformation and ensure durable performance for heavy-duty workloads.

✔ Wide Material Compatibility

Suitable for bending stainless steel, cold-rolled steel, aluminum, galvanized sheet, and painted metal.

✔ Energy-Saving and Cost Efficient

Pure-electric models reduce power consumption and oil maintenance, making them suitable for clean manufacturing environments.

✔ OEM / ODM Custom Design

Customization includes bending length, tonnage, controller system, tooling sets, backgauge axes, and automation integration.

STON CNC press brakes are widely used in:

• Electrical cabinets & distribution boxes

• Office & industrial metal furniture

• HVAC air ducts and ventilation components

• Home appliance metal panels

• Elevator doors & architectural metal materials

• Lighting fixtures & hardware products

• Machine enclosures & structural metal parts

Our bending solutions support both mass production and flexible small-batch fabrication.

Choosing the right press brake depends on the following factors:

1. Bending Length

Select a model that accommodates your maximum sheet length (e.g., 1600mm, 2500mm, 3200mm, 4000mm).

2. Material Thickness & Strength

Thicker or high-strength steel requires higher tonnage.

3. Production Volume

• Pure-electric for fast, clean, energy-saving bending

• Hydraulic servo for heavy-duty, high-load bending tasks

4. Required Accuracy

Choose a controller with multi-axis synchronization (Y1/Y2 + X/R/Z1/Z2).

5. Tooling Compatibility

Our press brakes support standard punches, dies, radius tools, hemming tools, and custom tooling sets.

If needed, STON engineers can provide a full selection guide based on your drawings and production requirements.

• Hydraulic servo press brake: High force, suitable for thick materials.

• Pure-electric press brake: Fast, quiet, energy-saving, ideal for clean workshops and thin to medium sheets.
