PRODUCTION SYSTEM ENGINEERING
Resolving Switchgear Fabrication Obstacles
How our heavy industrial framing, turret setups, and proportional hydraulics resolve high-volume switchboard panel fabrication challenges.
CHALLENGE
Frequent Tooling Die Swapping
Impact: Swapping punch dies manually for different switchboard bay layouts wastes up to 45 minutes per shift, severely bottlenecking high-volume B2B contract assembly lines.
DH CNC SOLUTION: MULTI-STATION INDEX TURRET
Our workstations feature 6 to 8 active station rotary turret punch blocks. Operators program multiple shapes (round, slot, square) in a single run, reducing swap downtime to zero.
CHALLENGE
Punching Alignment & Pitch Drift
Impact: Thermal expansion and split-body structural framing drift during repetitive punching cycles cause hole pitch tolerances to exceed ±0.5mm, leading to bay assembly alignment failures.
DH CNC SOLUTION: MONOBLOCK PRE-CALIBRATED CAST FRAME
Every DH CNC workstation features a single-piece pre-tempered stress-relieved monoblock frame. Holes remain aligned to within ±0.15mm pitch pitch pitch, even under continuous heavy loads.
CHALLENGE
Excessive Copper Shearing Burr
Impact: Heavy burrs on 10mm or 12mm switchgear connection busbars create high contact resistance and local heat build-up, failing strict utility grid commissioning standards.
DH CNC SOLUTION: GERMAN PROPORTIONAL DUAL-COLUMN SHEAR
Our dual-column guided shearing unit maintains a perfectly vertical shear path. Zero-waste single-cut blades guarantee clean, burr-free edges that pass inspections without post-processing.
