During operation of a high-speed slitting machine, if the cutting tool exhibits lateral oscillation, it will result in dimensional defects. For instance, defects may occur due to discrepancies between the tool's lateral oscillation and its outer diameter dimensions. Since tool lateral oscillation cannot be zero, its typical load-induced oscillation ranges from 0.03 to 0.05 mm. This stems from precision errors in blade thickness, inner diameter, and spacer width, as well as warping caused by lateral stresses during thick plate shearing.
During slitting machine operation, lateral warping in steel plates causes width dimensional defects. This occurs because products sheared under warped conditions measure slightly larger than the tooling set value.
As slitting machines operate, fitting errors develop in spacers, tools, and other components. Typically, thickness tolerances for spacers and tools are 0.005 mm. When multiple blades are used, cumulative errors increase. This stems from improper upper tolerance settings, as slitting machine-cut products consistently exhibit slight lower tolerance in width compared to blade-matched dimensions.
Therefore, anticipating this lower tolerance deviation is essential when determining spacer dimensions during blade matching. The cutting method employed must also be considered. Comparatively, when slitting machines utilize straight-pull cutting, increased coil tension eliminates transverse warping, leading to dimensional under-tolerance.
Before operating a slitting machine, it is essential to understand its fundamental safety protocols to ensure smooth production. Below are the basic safety points for operating high-speed slitting machines.
I. Environmental Requirements for Slitting Machine Operation:
The machine should be installed in a location with appropriate temperature, dryness, ventilation, good lighting, and convenient access for operation. Additionally, maintain a clean operating environment during daily use and regularly clean the machine to keep it in good condition.
II. Operational Requirements for Using the Slitter:
Use high-quality longitudinal and transverse cutting blades. The machine should perform fixed-length cutting on entire coils or sheets of raw material. Length control for fixed-length slitting must accommodate both static and dynamic cutting modes. The critical performance metric for fixed-length slitting is cutting precision, ensuring consistent finished product lengths. Slitting length settings should be continuously adjustable. If actual cutting lengths deviate, calibration must be performed by adjusting parameters.
This concludes the introduction to fundamental safety operation points and environmental requirements for high-speed slitting machines. The above represents solely the manufacturer's personal perspective!
