0.2-1.5mm thickness JZ20-Z series metal plate leveling machine

It’s fully automatic four-high roller leveler machine, it equip with smaller diameter(φ20mm) leveling rollers, so it’s more suitable for thin material.

Material can be processed:
All kind of Steel, Aluminum, copper, stainless steel, mesh sheet, laser cut plate, alloy plate and other metal plate products.

Use area:  
Mainly thin stamping parts, sheet metal parts, electrical appliances parts fabrication etc.
It equip with a large number of leveling rollers arranged in multi-layers and a very small spacing between each other, then based on "Bauschinger effect", sheet metal was repeatedly twisted to make metal fiber gradually consistent, eliminate internal stress, restore and improve the flatness. The stagger arranged support rollers ensure leveling rollers bearing heavy pressure in balance without bending deformation, keeping the whole equipment have enough rigidity. Upper and lower support roller column & upper and lower leveling roller group making up four-high layers structure, ensuring stable, efficient and high-quality leveling performance.

Machine main feature
It's four-high roller level precious leveling machine, there are both support assistant roller set upper and lower leveling roller set. All rollers were well processed to ensure leveling accuracy.

All leveling rollers adopt high quality bearing steel, finished quenching and tempering, precious machining, hard chrome plating, grinding etc. Surface hardness comes 58±2°(chrome layer thickness ≥0.05mm)

All backup roller(support roller) adopt Japan export roller bearings. There are 2 columns or more columns backup rollers uniformly distributed upper and lower leveling roller sets, making leveling rollers bears pressure in balance.

All gears adopt material of 20CrMnTi, finished forging, tempering, surface carburization, precious grinding etc. coming to grade IT6.

Main bearings are Shielded and sealed NSK bearing made in JAPAN, it can well reserve itself stocked lubrication oil and prevent dust enters, so it doesn’t need to add lubrication oil on bearings.

Roller gap adjusted by electric, so operator just need to set producing data in the HMI then it can adjust leveling roller gap automatically don’t need to crank the two hand wheels to adjust leveler’s straightening performance for manual model leveler.

High precision and perfect working performance
