Shop-floor Notes on a 0.7mm Steel sheet simple slitting machine

If you work with thin-gauge coils for HVAC, roofing, or shelving, you already know: simplicity wins. The current industry trend is “small-footprint, fast-changeover” slitters that handle 0.3–0.7 mm coils with minimal fuss and a predictable edge. I’ve seen shops in Hebei and Ohio both chasing the same thing—consistent slit width, tame burrs, and quick setups.

What it is, where it’s from

This 0.7mm Steel sheet simple slitting machine is a compact line from SHIBAWUXING VILLAGE BO TOWN, CANGZHOU CITY, HEBEI PROVINCE—an area that, frankly, turns out a lot of practical coil-processing kit. Description in plain words: a simple slitter for 0.3–0.7 mm, slitter blade adjustable. Nothing flashy, which is sort of the point.

Process flow (typical)

Decoiler → Pinch/leveling (light) → Slitting head (adjustable knives on spacers) → Scrap winder → Recoiler → Banding. Materials: galvanized, pre-painted, and mild steel strip, 0.3–0.7 mm. Methods: knife spacing by feeler + gauge blocks; tension control via friction clutch. Testing: slit-width caliper checks each shift; burr and camber checks per internal SOP; safety per ISO/CE checklists.

Product specs (typical, field-verified)

Material thickness	0.3–0.7 mm
Max coil width	≈ 1,250 mm (real-world use may vary)
Slit strands	2–10 (depending on strip width)
Line speed	0–35 m/min (typical shop settings 18–28 m/min)
Blade material	SKD11/HCr12MoV, 58–62 HRC
Slit width tolerance	±0.05 mm on 0.5 mm GI (around 25 m/min)
Edge burr	≤0.03 mm (with fresh knives; test coils may vary)
Service life	Blades: 6–12 months typical; spacers: multi-year with care
Certs (upon request)	CE, ISO 9001; electrical per IEC 60204-1

Where it fits

• HVAC/duct shops needing fast narrow strips
• Roofing and cladding lines (GI/PPGI)
• Furniture/shelving fabs cutting light-gauge mild steel
• Appliance back panels and trim strips

Many customers say the noise profile is lower than expected, and (surprisingly) a single operator can run it after a day of training. To be honest, that’s the charm of a 0.7mm Steel sheet simple slitting machine: less to go wrong.

Advantages I’ve noticed

• Quick knife setup; spacer stack is intuitive
• Good burr control on coated stock when knives are fresh
• Small footprint, easy to relocate
• Honest throughput for light gauges; energy use stays modest

Vendor comparison (indicative)

Vendor	Price band	Typical tolerances	Service/Lead time
LW (this model)	Mid	±0.05 mm; burr ≤0.03 mm	≈ 25–45 days; remote support
Budget import	Low	±0.08–0.10 mm; burr varies	Longer lead; limited spares
Premium EU	High	±0.03–0.04 mm; excellent edge	Fast service; highest cost

Customization options

Knife OD/ID, spacer kits for common widths, felt/brush wipe for PPGI, digital readout for knife gaps, upgraded recoiler clutch, and safety package aligned to ISO 12100. I guess the digital gap readout is the most popular add-on lately.

Field test snapshot

Internal FAT on 0.5 mm GI, 1,000 mm width at 25 m/min: slit tolerance ±0.05 mm, burr 0.02–0.03 mm, camber ≤0.2 mm/2 m, coil changeover 18–22 min. Real-world use may vary with material hardness and operator experience.

Brief case notes

• Roofing shop, 0.45 mm PPGI: reduced downstream edge grinding to near-zero.
• HVAC fab, 0.6 mm GI: 1 operator, 2 shifts, knives touched up monthly; uptime solid.
