The metal cut to length machine is also known as steel coil cut to length line, ctl line, coil cut to length line. It is simple and reliable to operate, and the stacking is neat. It has a high degree of automation, high precision in fixed length, and high flatness of the sheet. The metal cut to length machine is mainly composed of a frame, a knife holder, a drive motor, a transmission mechanism, a cutting device, etc. According to the required shearing length, the shearing data is input. After the switch is turned on, the drive motor drives the transmission mechanism to move the knife holder horizontally to cut the material into the required length. The steel coil cut to length line has the advantages of high precision, fast cutting speed, easy operation, simple maintenance, and durability. It is widely used in the processing and sheet metal cutting.

1. Feeding device: feeds metal sheets or coils into the production line.

2. Cleaning/pretreatment unit: removes possible dirt or coating.

3. Cutting unit (shear-to-length machine): core equipment, which cuts metal sheets or coils horizontally with a knife.

4. Stacking device: stacks or loads the cut metal sheets onto a transport vehicle.

1. Feeding and pretreatment: Raw materials are fed into the ctl line and go through possible cleaning or pretreatment units.

2. Transverse cutting: Metal sheets or coils are cut by transverse shears to cut them into the required width or length.

3. Stacking and packaging: The cut metal sheets are stacked or loaded, ready for further transportation or processing.

1. Wear work clothes neatly and wear work hats.

2. Before starting, check whether the metal cut to length machine tool handle and operating parts are normal.

3. The material must be clamped correctly and checked whether the leveling and straightening equipment is turned on synchronously.

4. After loading the material, the center positioning should be measured to check whether the hole spacing is correct.

5. The ctl line must be stopped and the speed must be changed. When the machine tool is running, it is strictly forbidden to touch the material with your hands, and the mold and motor cannot be touched with your hands.

6. It is strictly forbidden to place work, measuring tools, gloves and other items on the machine tool guide rails and molds.

7. Do not leave the ctl line tool after starting up, and concentrate on operating.

8. When leaving get off work, wipe the steel coil cut to length line tool, tidy up the site, and cut off the power supply of the machine tool. Lubricate the machine tool gears.

9. During the processing, if the steel coil cut to length line tool is found to have abnormal operation sound or a fault occurs, the power supply should be cut off immediately, the fault should be diagnosed or the manufacturer should be notified. 

Maintaining the normal operation of metal cut to length machine equipment requires regular maintenance, including but not limited to:

- Clean the ctl line regularly to ensure the smooth flow of cutting tools and transmission parts.

- Check and adjust the metal cut to length machine's tools to ensure the sharpness and fixation of the tools.

- Lubricate the key parts of the metal cut to length machine regularly to extend the service life of the equipment.
