The Closed-Type CNC Double Table Busbar Processing Machine integrates punching, shearing, and bending with Siemens PLC control for precision (±1° bending accuracy). Featuring dual worktables, 3 stations operate simultaneously to boost efficiency—handles copper/aluminum busbars up to 250mm width. Equipped with a 6-in-1 turret punching structure, dual safety controls, and surface protection, it supports custom dies for special processing (flattening, twisting, crimping). CE & ISO 9001 certified, ideal for batch production.
Product details
Closed-Type CNC Double Table Busbar Processing Machine features punching, shearing, and bending workstations. These stations can operate simultaneously or sequentially, significantly reducing processing time and boosting production efficiency. The bending station utilizes Siemens PLC control (Germany). Its primary function is processing copper and aluminum busbars of various specifications. Simply select the required workstation to quickly and conveniently perform operations on copper/aluminum bars, including shearing, punching (round holes, elongated holes), horizontal/vertical bending, U-bending, embossing, flattening, twisting, and cable lug crimping.
Punching Unit:
Six-in-One Turret Structure: Precision-engineered from ductile iron forging, ensuring absolute concentricity of upper and lower dies.
Versatile Tooling: Holds 6 punch dies for 6 hole types. Accommodates dies of different sizes/shapes, eliminating frequent changeovers. CNC-machined die mounting holes ensure high precision and long service life.
Triple Positioning: Positioning pins, ruler, and optical guide.
Surface Protection: Ensures no surface marks on workpieces.
Custom Hole Capability: Utilizes specialized dies for non-standard holes (e.g., round, square, elliptical).
Dual Safety Controls: Foot pedal and push-button limit switches.
Shearing/Cutting Unit:
Precision Cut: Sharp blades with dual-column shear structure guarantee flat, clean cuts – no droop, burrs, or scrap.
Dual-Pressure System: Prevents material lifting at corners.
Dual Safety Controls: Foot pedal and push-button limit switches.
Bending Unit:
Dual Worktables: Enables simultaneous, non-interfering operation of all three units (shear, punch, bend).
Closed Bending Structure: Ensures uniformity during flat bending and embossing, enhancing repeat positioning accuracy for batch production.
Siemens PLC Control: Delivers high bending precision (±1° bend angle accuracy, ±0.5° repeatability).
Multi-Function via Tooling: Change dies for horizontal bends, vertical bends, U-bends, embossing, flattening, twisting, and lug crimping. Features automatic bend angle control.
Efficiency & Storage: System includes memory function for easy storage and recall of settings. Automatic stop timers per station enhance energy efficiency.
Direct Input: Simply input height/length to produce parts (e.g., Z-bends).
