Working with metal part<\/a> by turning<\/a> or milling<\/a>, the machined metal chip always entangling metal parts. <\/p>\n\n\n\n

Normally, we can met following metal chip problems:<\/h2>\n\n\n\n
\"metal

1.Metal Chip winding, workpiece can not be loaded and unloaded<\/p>\n\n\n\n

2.Metal Chips must be removed after the machining finished.<\/p>\n\n\n\n

\"metal

3.Metal Chip winding and outlet blockage<\/p>\n\n\n\n

4.Metal Chip winding, tools life short and damaged easily.<\/p>\n\n\n\n

Do you have any chip trouble? If so, it means that you are not familiar with the workpiece machining<\/a>. If this continues, someone else has processed 100 pieces, and you may only have processed 90!<\/p>\n\n\n\n

    What are the methods of Metal chip breaking?<\/h3>\n\n\n\n
    1. Increasing chip thickness after feeding is beneficial to chip breaking<\/li><\/ol>\n\n\n\n

      2.The radius of cutter tip roundness decreases and chip thickness increases.<\/p>\n\n\n\n

      3.Reduce the front corner<\/p>\n\n\n\n

      Chip compression ratio = hc\/h<\/strong><\/p>\n\n\n\n

      1. The bigger the compression ratio is, the easier chip breaking will occur. At the same time, the cutting resistance will also increase.<\/li>
      2. Compression ratio is related to linear velocity Vc. When Vc decreases, compression ratio increases, so reducing linear velocity is also beneficial to chip breaking.<\/li>
      3. The decrease of the front angle, the large chip deformation and the increase of the compression ratio are beneficial to chip breaking.<\/li>
      4. <\/li><\/ol>\n\n\n\n

        Use sharp edge cutting tool<\/h2>\n\n\n\n

        As photo show, under the same feed conditions, the blade has sharp edges, which is conducive to metal chip breaking.<\/p>\n\n\n\n

        Increasing the main deflection angle and thicker chips are beneficial to chip breaking<\/p>\n\n\n\n

        Protruding chip breaking groove to promote chip breaking<\/p>\n\n\n\n

        Scraping the surface of the chip from the protuberance of the chip breaking groove produces a dent—-Significant increase in chip thickness—Promoting chip breaking is highly damaging<\/p>\n\n\n\n

        The contact area with chips decreases and the chips discharge smoothly due to smooth contact with protrusions—Less damage to cutting tools<\/p>\n\n\n\n
