Frequently Asked Questions (Supplemental)

1) How often should a shutter door roll forming machine be lubricated?

• For two-shift operations, lubricate bearings and guideways weekly and gearboxes per OEM hours (typically every 2,000–4,000 hours). Verify with the machine’s manual and oil analysis if available.

2) What are the telltale signs that rollers need regrinding or replacement?

• Persistent surface marks, edge waviness, or camber in the shutter strip despite correct alignment; visible pitting or flaking; increased forming load/amp draw; out-of-spec panel crown.

3) Which coolant or forming lubricant is best for galvanized steel shutters?

• Use a low-residue, chlorine-free, water-dilutable synthetic or semi-synthetic formulated for roll forming of coated steels; target 3–7% concentration and maintain pH 8.5–9.5 to minimize white rust. Confirm compatibility with downstream painting.

4) How do I reduce downtime during tool changeovers?

• Standardize setups with color-coded shims, torque-marked fasteners, and QR-coded recipes; use quick-release roll spacers, preset side guides, and checklists. Aim for under 20 minutes per profile change on modern shutter lines.

5) What preventive checks reduce electrical faults on shutter lines?

• Quarterly thermography on MCCs/drive cabinets; tighten terminals to spec; replace aging contactors/relays per cycle count; verify encoder coupling set screws; back up PLC/HMI recipes and perform UPS health checks.
