STON PBS Series Electro-Hydraulic Servo Press Brake

What types of sheet metal can your flexible bending center process? What is the thickness range?

Our machines is suitable for common sheet metals such as stainless steel, carbon steel, aluminum alloy, and galvanized sheet. The thickness range is 0.2mm-6mm, meeting needs of various industries, including home appliances, hardware, and cabinets. It also supports asymmetric and complex customized processes.

After purchasing the machine, do you provide installation, commissioning, and operator training?

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.

Can you provide customized solutions for special needs?

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.

What is your after-sales response time in the event of a malfunction? How do you provide technical support?

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.

What is the warranty period for your various sheet metal processing equipment? What does the warranty cover?

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.

For long-term use, is the warranty extended? How are extended warranty plans formulated?

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.

What payment methods are available for equipment purchases? Do you support international payment terms?

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.

What is a CNC press brake machine and how does it work?

A CNC press brake is a computer-controlled bending machine used to process sheet metal with high precision. It works by using a punch and die to apply force on the metal, creating bends at specified angles. With CNC technology, operators can program multiple bends in one setup, ensuring accuracy, repeatability, and efficiency.

What are the advantages of CNC press brakes compared to manual or hydraulic press brakes?

CNC press brakes offer higher bending accuracy, faster production speed, and intelligent compensation functions. Unlike traditional hydraulic press brakes, CNC machines feature servo-driven systems that reduce energy consumption, minimize noise, and improve efficiency. They are ideal for both small-batch customization and large-scale production.

What industries commonly use CNC press brake machines?

CNC press brakes are widely used across sheet metal fabrication, automotive, aerospace, electrical cabinets, kitchenware, furniture, and construction machinery. They are especially suitable for industries that require complex bends, consistent quality, and efficient production.

What industries use CNC press brake machines?

CNC press brakes are widely used in industries such as automotive, electrical cabinet manufacturing, HVAC ducting, kitchen appliances, furniture production, and metal fabrication workshops. With their ability to handle various sheet metal bending tasks efficiently, they are ideal for companies requiring durable, flexible, and high-precision bending solutions

What maintenance is required for a CNC press brake?

Routine maintenance includes:

Checking and lubricating ball screws and linear guides、Monitoring the hydraulic system or servo motor (depending on model)、Inspecting grating rulers and sensors for accuracy、Replacing worn punches and dies、Ensuring the control system and safety devices are functioning properly
Proper maintenance helps extend machine life and guarantees consistent bending quality.
