CYMBER Busbar Fabrication Workshop Process Overview

Workshop Overview

The CYMBER busbar fabrication facility covers approximately 1,000 m² and specializes in high-precision copper and aluminum busbar processing for medium- to large-scale switchgear manufacturers, data centers, and industrial power projects. The workshop operates a complete in-house production chain—from raw material preparation to final packaging—supported by a full suite of CNC and dedicated equipment to ensure short lead times, high dimensional accuracy, and consistent surface quality for high-volume orders.

Detailed Process Flow

1. Raw Material Warehouse & Laser Blanking Area A dedicated raw material warehouse stocks T2 copper and 6063 aluminum busbars in widths of 30–300 mm and thicknesses of 3–20 mm. All incoming materials are recorded with full batch traceability. Blanking is performed on high-power fiber laser cutting systems with automatic loading tables, achieving cutting tolerances of ±0.1 mm. The laser process produces stress-free edges with no heat-affected oxide layer, eliminating the risk of cracking during subsequent bending—a capability that sets the facility apart from conventional mechanical shearing methods.

2.CNC Drilling & Milling Area Two high-speed CNC drilling and tapping centers (24,000 rpm spindle, automatic tool changer) complete drilling, counter-sinking, slot milling, and threading in a single setup. Positional accuracy is maintained within ±0.05 mm, fully compliant with the stringent requirements of KYN, MNS, and GCS switchgear systems. Bench drills are retained for low-volume or special-hole applications.

3.Punching & Notching Area Multiple CNC hydraulic turret punch presses (300–500 kN) equipped with extensive tooling libraries deliver clean, uniform corners and notches while maintaining superior batch-to-batch consistency compared to manual methods.
4.CNC Bending Area Four CNC hydraulic press brakes (160–300 T, up to 4 m bending length) feature automatic back-gauge positioning and achieve angular tolerances of ±0.5°. For thick busbars (≥12 mm), segmented bending combined with localized induction heating ensures wrinkle-free results and zero cracking.

5.Surface Finishing Area
1.Wide-belt sanding stations remove heat-affected zones and oxides rapidly.
2.Magnetic + brush composite deburring machines produce consistent edge radii of R0.2–R0.5 mm on all edges.
3.Manual polishing stations achieve surface roughness Ra ≤ 1.6 μm when required for subsequent tin or silver plating.

6.Pre-Plating Cleaning & Quality Inspection Every busbar passes through an ultrasonic cleaning line followed by DI water rinsing and hot-air drying to guarantee maximum plating adhesion. Comprehensive inspection equipment—including coordinate measuring machines, optical projectors, and coating thickness testers—ensures a minimum 10 % sampling rate per batch.
7.Finished Goods Warehouse & Packaging Finished busbars are stored by project in clearly identified zones, each set tagged with a unique QR code linking to drawings, material certificates, and inspection reports. Packaging utilizes custom wooden cradles, moisture barriers, and protective corner guards suitable for long-distance ocean freight and on-site crane handling.

With a layout philosophy of “warehousing built around production, production built around projects,” the CYMBER facility consistently achieves 3–5 day lead times from order release to shipment. The workshop has established long-term partnerships with Tier-1 suppliers to Schneider Electric, ABB, and Siemens. Large-scale switchgear and EPC companies are welcome to visit and discuss cooperation opportunities.
