Stainless Steel Sheet Cut To Length Machine
Stainless steel sheet is high quality steel, requires high precision high quality cut to length line machine
Stainless steel, such as SUS200, SUS300, SUS400 series, compared with normal carbon steel Yield strength ≤270Mpa Tensile strength≤465Mpa, stainless steel sheet strength Yield strength ≤500Mpa Tensile strength≤800Mpa

Characters:
- STS coil cut to length line must be high precision and robust.
- Uncoiling stage: Include Coil storing saddle covered with PU rubber plate, Coil loading car with PU rubber plate,Single mandrel or double mandrel uncoiler, Coil head snubber roller, peeler shoveling plate
- High precision Leveler: 4Hi or 6Hi. 4Hi is two layers work rollers and two layers backup rollers, 6Hi plus two layers middle rollers between work rollers and backup rollers. Leveler drive is DC or AC motor, reducing gearbox, distribution gearbox and universal joints.
- Pit loop Or Transmission roll table. Rubber coated rollers to contact stainless steel sheet.
- Servo cutting to length for thickness below 6mm and above 6mm usually rotary encoder(and/or Film Laminating)
- Sheet Discharging stage:Include Belt Conveyor,pneumatic sheet receiving arms,X lifting table, exit car or roll table
heavy STS coil cut to length
Market:
- Stainless steel sheet cut to length line is becoming more percentage with the market requiring more stainless steel sheets, the SS sheet surface is bright, must be nicely protected in the uncoiling, leveling and cutting process.
- Fast cutting to length is needed because customers want enough production within certain time and land area. Thus, high speed cutting line, either flying shear or stop shear, is popular.
- Sheets stacking must be fast and in order, receive one sheet,drop down and push it neatly.
- Automation system is there in electric control, big touch screen and PLC program.
