  For many certain users, their understanding of their own tool requirements is very clear. However, in recent years, the metal cutting industry has developed rapidly, and tool suppliers have many new tools, new ideas, and new experiences for customers to refer to in terms of tool configuration. In addition, the tool supplier learned from many successful or failed examples during cooperation with other users, which are also good reference. Therefore, it is recommended that users must discuss with the tool supplier when buying slitting tools and make sure that they fully understand your own needs, so as to find the most economical and suitable solution.
  Since the configuration of the slitter knife is closely related to investment, users need to correctly position their needs based on sufficient market research. If the requirement is too high, the investment will be increased, and if the requirement is too low, it will be difficult to meet multiple strip specifications in the future.
  The main data that customers need to provide when purchasing precision tools are:
  1. The thickness range of the cutting material. The thickest and thinnest thickness is an important parameter that determines the clearance, which determines the accuracy and setting of the tool and the thin spacer. In addition, it is also an important parameter that determines the number of bonded stripper ring groups on the female unit and the number of groups with different knife thicknesses.
  2. The width range of the incoming material. The widest and narrowest incoming coil widths are important parameters that determine the width and number of wide spacers.
  3. The maximum number of strips. The maximum number is an important parameter that determines the thickness and number of knives, bonded stripper rings, and thin spacers.
  4. The tensile strength of the material. The tensile strength is an important parameter that determines the material and hardness of the knife.
  5. Strip width increments, such as 0.01mm, 0.1mm, 0.5mm, 1mm, etc. The width increment is an important parameter that determines the configuration of the thin spacers.
  6. Clearance increments, such as 0.0025mm, or 0.005mm, 0.01mm, etc. The increment of the clearance is also an important parameter that determines the configuration of the thin spacers.
  7. The length of the arbor (from the shoulder to the nut). The length of the arbor is also an important parameter that determines the number of wide spacers.
  8. Is clearance in female or male unit? This relates to the strip width. If the clearance is set in the male unit, the strip will be narrower, often in a negative tolerance. At this time, the nominal thickness of the knife may be intentionally reduced by 0.01mm, 0.02mm. In addition, the specifications and number of thin spacers may also change greatly.
  9. The setup position. The advantages and disadvantages of positioning with the shoulder or the center of the slitting machine will be explained in another article, but for the knife supplier, it will affect the design of the software.
