CUT-TO-LENGTH · HIGH-SPEED

High-Speed Cut-to-Length Line

Synchronised cutting: punches, V-notch and shears strike on one beat — the strip never stops. High volume, fast cycle times, frequent changeovers.

Steady batches, few lamination types? → See the Standard Line

How it differs from the standard line

Cutting	Synchronised — strip never stops	Standard: step by step
Stations	All moving — change laminations, not dies	Standard: fixed or few moving
Feed	High-speed servo uncoil & feed	Standard: NC feed
Collation	Extended collation chain, no stops to unload	Standard: neat stacking, twin tables
Best for	High volume, frequent changeovers	Standard: steady batches, few types

Line speed, and what it means for your shift output

Peak feeding speed (300 / 400 class servo builds)up to 240 m/min

Typical rated speed (most builds)210 m/min

Recommended working speed120 – 180 m/min

Depends onsteel grade & flatness

Depends onlamination type and length

Depends onpunching pattern per sheet

Peak speed is a machine rating, not a shift figure. Real output follows this chain: rated feeding speed, minus cutting stops for each punch and V-notch, minus coil and job changeover, times shift utilisation. Short laminations with four punches per sheet run far below peak; long yoke sheets run close to it. Our engineers calculate the sheets-per-minute and cores-per-shift figure for your own lamination drawing before quoting – and that calculated figure, not the peak speed, is what goes into the technical agreement and the FAT.

Peak 240 m/min figures come from SRHJ300-24 and SRHJ400-24B class technical files; 210 m/min with a recommended working speed of 120-180 m/min is the common configuration. Formal speed for your project is fixed in the technical agreement.
