FAQ
Q: There is always a deviation in the length of the processed steel bars. How can this be solved?
A: First, check if the fixed-length baffle is locked tightly. If deviations occur, follow these two steps: ① Calibrate the levelness of the equipment with a level (the inclination of the foundation will affect the accuracy). ② Enter the parameter interface through the touch screen and recalibrate the servo positioning with a standard gauge block (it is recommended to cut three pieces for verification after calibration). Remember to keep the track clean daily, as the accumulation of iron filings can also cause inaccurate positioning.
Q: What could be the reason for the occasional inability to cut through, or the uneven cut when cutting?
A: Don’t worry. This is usually caused by blade clearance or parameter settings. First, check the gap between the upper and lower blades and adjust it to 0.5–1 mm (special attention should be paid to the inclined blade design). If the wear is severe, it is recommended to replace the original alloy steel blade. ② If cutting hard steel, the maximum shearing pressure can be increased on the touch screen. The number of bars sheared at one time should not exceed the upper limit marked on the equipment.
Q: What should I do if the equipment suddenly alarms and stops, and the screen shows a fault code?
A: Press the emergency stop button immediately. The most common alarms are: ① “E01” servo fault: After powering off for 3 minutes, restart and check if the cable is loose. ② “E05” hydraulic anomaly: Check if the oil level is within the marked range. If the oil temperature is too high, stop the machine for cooling. ③ For other codes, refer to the “Alarm Comparison Table” in the manual.
Q: How often should the equipment be maintained? What should be noted in daily use?
A: Daily maintenance is very simple. ① Before starting each shift, clean the tracks and apply lithium-based grease to the transmission chains. ② Check the hydraulic oil filter element every week and drain the accumulated water from the air storage tank. ③ Calibrate the fixed-length accuracy once a month.
Q: Our construction site has many specifications of steel bars. Can we process steel bars of different diameters simultaneously?
A: Yes, you can. Our double-sided storage racks can hold multiple specifications simultaneously. When switching, simply select the “Mixed Flow Mode” on the touch screen. It is recommended to group by diameter before processing. Thick steel bars should be placed on the lower layer of the material rack (for better load-bearing capacity), and thin steel bars on the upper layer. This way, transportation will be smoother.
Q: Can the extended material rack be customized?
A: If you need an extended material rack, please inform us in advance. We support modular customization and will follow up from design to installation to ensure it meets the requirements of the construction site.
