Big Aluminum Coil Plate High Precision Aluminum Slitting Line Machine 3.5 x 2200

Big Aluminum Coil Plate High Precision Aluminum Slitting Line Machine
 
Aluminum sheet is softer in body and smooth in surface, some aluminum sheet is hard and high tensile, so aluminum Coil sheet slitting must be:
1. high precision, machinining precision must be high, rollers surface is hard chrome coated or PU rubber coated,
2. each machine must cater to specific aluminum coil materials, harder or softer, the machine must consider each technical details in production process.
3. Machine power match with line speed, number of slitting, slitting precision.
4. the slitting tools for aluminum sheet is unique, slitting speed is high when aluminum sheet gauge is small.
aluminum sheets can be pure aluminum or aluminum alloy, most frequently 1xxx, 3xxx, 5xxx, 7xxx series aluminum sheets.
Aluminium sheet coils can be very big: coil width up to 2500mm, coil outer diameter up to 2600mm, weight up to 20-30T, the big aluminum coil slitting line has big capacity uncoiler and recoiler, cooperative with the middle precise slitting machine, the special point needs good technical design and control to give stable slitting process.
 
Features of aluminum sheet:

1. it has good plasticity, easy to be processed
2. aluminum sheet is light, its density is 2.7g/cm3, about one third of steel sheet
3. The strength of aluminum sheet can be improved by cold rolling and annealing.
4. Aluminum sheet has solid Al2O3 protection surface, is anti- corrosion.
5. Aluminum sheet is softer in body and smooth in surface, must be well processed.
