Precision Strip Straightening Machine JM4-200–600 | Yiming, Dongguan, China

Yiming's Precision Strip Straightening Machine, the JM4 series, flattens thin metal strip and sheet before it goes into stamping or further processing. It is offered in five models for material widths of 200, 300, 400, 500 and 600 mm.

It levels by passing the material through 19 rollers, 9 above and 10 below, set in a staggered arrangement that applies pressure to remove distortion. It handles stainless steel, copper, iron, aluminium and other thin plate materials from 0.5–4.5 mm thick.

Key Features

• Parallel roller dislocation and pressure levelling method with 19 rollers (9 upper, 10 lower)
• Roller adjustment by dial gauge, so setting is simpler and more accurate and needs no additional correction
• Levelling rollers made from bearing steel, heat treated and quenched to HRC 60°, then hard chrome plated and ground
• Oil-free bearings on both sides of the rollers
• Variable frequency speed control matches levelling speed to feeding speed
• Inductive rack type or photoelectric sensing available
