Milling Tools Resist Chatter, Pullout
IMTS 2018: New cutting tool geometries for Haimer’s Power Mill and Duo-Lock lines include designs for aluminum and mold steels.
New geometries for Haimer’s Power Mill line of solid carbide end mills and and Duo-Lock line of modular milling heads include designs for aluminum and mold steels. Unequal flute and helix designs provide chatter-free machining. The company’s tools are made from K20-K40-grade fine-grain carbide.
The latest tools include two- and three-flute end mills for aluminum, which are available in solid carbide or as a modular interface (Duo-Lock), four- to 10-flute end mills for working in steel, and various specialized cutting tools. Special tools include a multifunction chamfer spotting tool, four- and five-flute roughing mills for steel, a quadrant end mill, and ball nose end mills for steel and aluminum. All are available as solid carbide end mills or Duo-Lock interfaces.The company also offers the Basic Mill line
of solid carbide end mills and Duo-Lock milling heads for roughing, finishing and drilling. All tools are available with the optional Safe-Lock anti-pullout system.
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
Cutting holes by interpolating a face milling cutter may be a better process choice for many rough and even finish boring operations. Software improvements and better cutter designs allow expanding use of the versatile face mill for hole making.
The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.
