Best Quality Copper/Aluminum Busbar Fabrication MachineProduct Description:This
The LTMC 303E-3-S is a 300 kN three-in-one CNC busbar machine that punches, shears and bends copper and aluminum busbar up to 12 mm thick and 160 mm wide, built for Canadian switchgear, transformer and busway shops. Its servo-driven units share one worktable so a single operator moves from hole punching through edge shearing to bending without re-fixturing. The bending unit holds ±1° accuracy with ±0.3° repeatability, tight enough for stacked busbar joints in 600 V distribution assemblies. At 1420 kg and a 1800×1400×1480 mm footprint it fits a typical Ontario or Quebec fabricator's floor. Punching covers Ø4.3–Ø25 mm holes, covering the busbar termination patterns common in CSA-assembled switchgear.
303E-3-S — Punching force: 300 kN. Test condition: copper and aluminum busbar on the punching station. Result: 300 kN nominal force handles Ø4.3–Ø25 mm holes in 12 mm stock. Baseline: the manual 303U-3-C lists the same 300 kN punching force (family_ref.txt), so the servo version keeps the force class while adding CNC control.
303E-3-S — Max busbar size: 12 mm × 160 mm. Test condition: punching, shearing and vertical bending passes. Result: processes bar up to 12 mm thick and 160 mm wide at all three stations. Baseline: matches the 303U-3-C envelope (12×150–160 mm per family_ref.txt); the servo model reaches a full 160 mm width.
303E-3-S — Bending accuracy: ±1° with ±0.3° repeatability. Test condition: vertical bending of 12×160 mm copper bar. Result: ±1° bend angle and ±0.3° repeat on batch runs. Baseline: the 303U-3-C holds ±1° / ±0.5° repeat (family_ref.txt); the servo 303E-3-S tightens repeatability to ±0.3°, better for stacked joint fit-up in Canadian switchgear.
303E-3-S — Machine weight: 1420 kg. Test condition: as-shipped floor weight. Result: 1420 kg on a 1800×1400×1480 mm base. Baseline: the manual 303U-3-C is 1320 kg and the servo 303E-3-S spans 1420–1500 kg (family_ref.txt), reflecting the added servo drives.
The servo drives and control panel are configured for the supply specified at order; Canadian shops commonly run 208 V, 480 V or 600 V three-phase at 60 Hz. Confirm your incoming voltage with our team so we size the transformer and enclosure for panels assembled to CSA C22.2 requirements.
Machines ship from Jinan in a wooden case, typically by ocean freight to the GTA, Montreal or Vancouver, plus customs clearance on arrival. Your broker handles entry documentation; confirm current transit and clearance timing with our team before you place the order.
Standard punching, shearing and bending tooling ships with the machine, and common wear parts can be reordered. We support Canadian customers remotely by video and can advise on die sets and a short operator training session; confirm spare-part stock and training format with our team.
