Electric CNC Press Brake

Core concept: Why are pure electric bending machines more user-friendly for beginners? 1. Simplified operation: Fully electric control eliminates the need for complex hydraulic calibration, resulting in less noise and heat generation. 2. Precision self-protection: The servo system can precisely control the position and speed of the slider, with extremely high repeatability accuracy. Once adjusted, there is no need to worry about batch production. 3. Safety and Intelligence: Usually equipped with a more user-friendly graphical interface, anti-collision hand function, and misoperation prompts, etc. 4. Maintenance-free: No hydraulic oil is required, reducing maintenance steps and contamination risks.     The four-step method for beginners to easily get started Step 1: Preparations before commencement - Safety and understanding Read the manual: Spend 30 minutes browsing through the equipment operation manual to understand the emergency stop, various buttons and interface areas. Wear protective gear: Be sure to wear protective gloves (to prevent cuts), goggles (to prevent iron filings from splashing), and safety shoes. Get to know your workpiece Material: What is it? For example: cold-rolled steel plates, stainless steel, aluminum Thickness: How much? (e.g. 1.5mm Bending Angle: How many degrees should it be bent to? (e.g. 90° Size: What is the length of the bent edge?   Step 2: Machine Setup - Utilize the intelligent system This is the most crucial step. The control system of the pure electric bending machine is your "strongest assistant". Input parameters: On the control touch screen, select "New Program" or "Single Processing", and input: Material type Material thickness The V-groove opening of the lower die (generally, 6 to 8 times the thickness of the plate is selected; for example, a 12mm V-groove is chosen for a 1.5mm plate.) The system has recommended values. Target bending Angle Bending length Let the machine calculate automatically: Press the "Program" or "Calculate" key, and the machine will automatically calculate: Lower die position Bottom dead center of the upper mold (slider depth) Required pressure Rear stopper position Install the mold Power-off operation! Make sure the machine has completely stopped. According to the system suggestions, select the appropriate upper die (sharp knife, curved knife, etc.) and lower die (V-groove). Use a tool (an Allen wrench) to install it firmly, but do not over-tighten.   Step 3: Trial folding and fine-tuning - Patiently verify To perform the "trial folding" : Place a piece of scrap material of the same material and thickness as the workpiece, and press the foot switch or click "Single cycle" to conduct the trial folding. Measure the Angle: Use an Angle gauge to measure the Angle of the workpiece to be folded. If the Angle is too large (such as 95°) : It indicates that the bending is insufficient. Add the "bending depth" or "correction value" (for example, +0.1mm) on the control screen. The Angle is too small (such as 85°) : It indicates that the bending is too deep. Reduce the "bending depth" (for example, -0.1mm) on the control panel. Adjust the rear stopper: If the bending position is incorrect, adjust the front and back positions of the rear stopper. Repeated fine-tuning: Usually, after 2 to 3 attempts of bending and fine-tuning, a perfect Angle can be achieved. The advantage of the pure electric bending machine lies in that the adjusted parameters will be automatically saved and can be directly called up when bending the same product next time.   Step 4: Formal bending and mass production Confirmed to be correct: The Angle and size of the test folded piece are completely qualified. Batch bending Place the workpiece close to the rear stopper. Place both hands on both sides of the workpiece. Do not put them under the mold. Step on the foot switch to complete the bending. Repeat the operation and enjoy the stable repeat accuracy of the machine. First article inspection: Regularly spot-check the first article during batch production to ensure there are no deviations.   Have questions about the parameters of this model?

一. The "invisible" erosion of product quality caused by long-term unstable precision The problems caused by an unstable bending machine are far more than just a few defective products. 1.Batch inconsistency and assembly risks The 100 parts produced today are flawless, but the same batch of parts to be produced next month shows micron-level differences. This drift is a nightmare for the assembly line, leading to poor fit, increased stress on fasteners, and ultimately affecting the structural integrity of the entire product. Impact on you: High rework costs, delayed deliveries, and the collapse of customers' trust in your quality control capabilities.   2. The scrap rate has been quietly rising The attenuation of accuracy is usually gradual and difficult to detect immediately. Operators may spend more time on fine-tuning, but minor changes can quietly push up the scrap rate. These "silent" wastes are eroding your profits every day. Impact on you: Material costs have risen, and profit margins have been squeezed even before you realize the root cause of the problem.   3. Compromise between product performance and lifespan For load-bearing structural components or high-precision equipment casings, the designed bending Angle and radius directly affect their strength and fatigue life. Unstable accuracy means that the performance of key structural components cannot be guaranteed. Impact on you: The risk of the product failing prematurely at the customer's site increases, leading to warranty claims and damage to the brand's reputation. 二.What determines the long-term precision stability of an electric bending machine? This is not magic but is based on solid mechanical engineering and high-quality materials. 1. Frame rigidity and fatigue resistance design The core: The rack is the framework of the entire machine. We adopt an integral steel structure and optimize it through finite element analysis (FEA) to ensure that the deformation is kept to a minimum under long-term and asymmetric loads. Cheap racks or poorly designed racks will undergo "creep" over time, resulting in permanent loss of accuracy.   2. Durability of the compensation system: The cornerstone against torsion Core: The "deflection" of the worktable and slider is the number one enemy of precision. Our built-in hydraulic torsion compensation system has been meticulously calibrated. The quality of its cylinders and seals determines whether it can still provide uniform and precise compensation force ten years later. A low-quality compensation system will fail quickly, causing the middle Angle to bulge and making it impossible to process long workpieces.   3. Wear control of drive and transmission systems Core: Our fully servo electric system employs pre-tightened high-precision ball screws, which have almost no backlash and minimal wear compared to rack and pinion or belt drives. The closed-loop control of the servo motor ensures that the position of each stamping is absolutely accurate. The durability of this system directly determines the period during which its precision is maintained.   4. Intelligence and adaptability of the control system Core: A high-end control system is not merely about issuing instructions. They can correct the rebound in real time through automatic Angle measurement and feedback. In the long term, an intelligent system that can learn and adapt to the properties of materials is the key to offsetting the micro-aging of mechanical components.   if you have more ideas, please contact us!

1.Why can electric bending machines achieve such high precision? This is inseparable from its driving principle: Direct drive, no intermediate variables: The all-electric bending machine uses a servo motor and a ball screw to directly drive the slider to move. This structure does not have the problems such as oil temperature changes, oil viscosity and leakage that exist in hydraulic systems, and these are precisely the main reasons for the precision drift of hydraulic presses. Closed-loop control: The system monitors the positions of the servo motor and the slider in real time through a high-resolution encoder and feeds the data back to the controller. Once a minor deviation is detected, the controller will immediately issue an instruction for correction, forming an accurate closed-loop control. No mechanical clearance: The precise ball screw and rigid structure design ensure an extremely small backlash, further guaranteeing positional stability.   2. Understand the accuracy indicators: positioning accuracy vs. repeat positioning accuracy When evaluating a bending machine, there are two related but distinct concepts: Positioning accuracy: It refers to the overall error between the actual position reached by the slider and the target position required by the instruction. It is more like an "absolute" precision. Repeat positioning accuracy: It refers to the consistency of the slider when it returns to the same target position in multiple attempts. This is a more important "relative" accuracy indicator. A vivid metaphor: Imagine shooting at a target. High positioning accuracy means that all bullet holes are concentrated near the aiming point (bullseye). High repeat positioning accuracy means that all bullet holes are closely clustered together, even if they may not be on the bullseye. For bending processing, the repeat positioning accuracy is often more important than the absolute positioning accuracy. Once the perfect bending position is found through the first piece's debugging, the machine must be able to precisely return to that position tens of thousands of times to ensure that the angles of all workpieces in mass production are consistent.   3. Factors affecting actual accuracy Even if the repeat positioning accuracy of the machine itself is very high, the following factors still need to be considered in actual production Eccentric loading processing: When the bending force is unevenly distributed at both ends of the worktable, it may cause slight torsional deformation. High-end electric bending machines will adjust the positions at both ends in real time through an automatic Y-axis compensation function to counteract this effect. Mold and machine tool rigidity: Any minor elastic deformation will affect the final outcome. Both the machine tool itself and the upper and lower dies used must have sufficient rigidity. Ambient temperature: Although the electric bending machine is not sensitive to temperature, extreme temperature changes in the workshop may still have a minor impact on the mechanical structure.   4. How to verify this indicator? When communicating with suppliers, you can ask questions like this to get reliable answers: May I ask what the exact repeat positioning accuracy listed in your official technical specification is? On what standards (such as ISO, JIS) is the test based?" Was this precision data measured in a cold or hot machine state? High-performance machines should maintain accuracy throughout the entire operating temperature range. Could you provide a third-party test report or demonstrate it on the spot during the test run? Summary ±0.0004 inches (±0.01 millimeters) can be regarded as the reference line for high-performance all-electric bending machines. Many top manufacturers can even offer an accuracy of ±0.0002 inches (±0.005 millimeters) or higher.   if you have more ideas, please contact us!
