Tianjin Wujia CNC Machine Tool Co., Ltd. is one of the leading manufacturers and suppliers of pb-3012 all-electric servo cnc press brake in China. Please rest assured to wholesale high quality machines at competitive price from our factory. Good service and cheap products are available.
The PB-3012 All-Electric Press Brake delivers 30 tons of pressure with a 1.2m bed length, built for precision bending of medium-sized sheet metal parts. Dual servo motors drive the machine with 6-axis linkage and magnetic scale closed-loop control, achieving ±0.01mm positioning accuracy. The fully electric design eliminates hydraulic systems-clean and energy-efficient.
Structural Features
• One-piece welded frame optimized with FEM analysis for high rigidity and zero deformation under long-term loads.
• Dual Y-axis independent servo control with imported magnetic scales for real-time synchronization; supports off-center and conical bending.
• Precision-ground ball screw and hardened reducer transmission for smooth, low-noise operation. Lubrication ports make routine maintenance quick and easy.
• 4-axis backgauge (X/R/Z1/Z2) with retraction function; dual auto-fingers slide left and right for flexible positioning.
• Single/Double-V interchangeable workbench with quick push-pull wedge clamping for fast tool changes, compatible with standard and custom tooling.
• Two sets of movable front supports provide stable handling for long workpieces, improving safety and ease of operation.
Core Advantages
1. High Precision: Magnetic scale closed-loop control ensures excellent angle consistency across batch production.
2. Truly Clean: All-electric drive means no oil leaks. Power is delivered on demand, reducing energy consumption and operating noise.
3. Low Maintenance: No hydraulic oil or seals to replace. Core components from trusted brands keep failure rates minimal.
• Foundation drawings provided. On-site commissioning and free operator training included.
• 12-month warranty on the full machine. Core components replaced free of charge if defective (excluding consumables).
• Fast response with remote technical support and spare parts supply. On-site service available upon agreement.
Selection Guide
When selecting the PB-3012 All-Electric Servo CNC Press Brake, consider the following:
1. Bending Capacity: For workpieces with a maximum bending length ≤ 1200mm, this model is the ideal choice. For larger dimensions, a bigger model is recommended.
2. Tonnage Calculation: Calculate the required bending force based on material type, thickness, and bending length. A 20%–30% safety margin is recommended to prevent long-term overload.
3. Process Requirements: For complex operations such as conical bending, off-center bending, or multi-step bending, the 6-axis linkage offers superior adaptability.
4. Configuration Selection: Choose the appropriate CNC system and optional features based on operator skill level and production automation needs.
1. Store indoors in a dry, well-ventilated area. Floor loading capacity must exceed 3200kg. Never store outdoors to avoid moisture and corrosive dust damaging precision components.
2. Before long-term storage, apply anti-rust grease to precision parts such as guide rails, ball screws, and magnetic scales. Cover the entire machine with a dust-proof cover.
3. Disconnect the main power supply and unplug all external connectors. Periodically check electrical components for moisture.
4. Do not stack heavy objects on the machine to prevent frame deformation. Perform anti-rust inspections and maintenance every 30–45 days.
