10,000-Ton Turntable and TGV Laser — Two Diverging Paths: Scale and Precision

Key news summary.

SFA and LS Cable & System have begun sequential shipment of turntables for a dry-coating line to a Panasonic plant in the US. Contract value approximately KRW 150.0 billion, with dozens of units to be supplied through the end of 2027. Equipment diameter exceeds 40m at maximum, fabricated domestically in split sections and assembled on-site.

ABACO/ABATEC has started operating a glass-substrate TGV (through-glass via) pilot laser line. Target substrate 515×510mm. Laser processing equipment: AXIUM AP-250K. Target processing speed: 10,000 holes/sec. Target tolerance: ≤5µm (disclosed target value).

■ Equipment perspective impact analysis

For turntables, load-bearing capacity and rotational stability are the key parameters. At the 40m-diameter scale, self-weight deflection and eccentric loading govern rotational precision, and the split-fabrication/on-site-assembly method itself requires rigidity management at the field joints.

TGV equipment sits on the opposite axis of the problem. The core issue is not load but positional repeatability — maintaining 5µm tolerance at a processing speed of 10,000 holes/sec requires thermal-deformation management across the stage transport system and the optical system to proceed in parallel.

One-line summary. Even under the same label of “precision equipment,” a design that withstands self-weight and a design that repeats position are different problems.
