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.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
The right choices in tooling and technique can optimize the thread turning process.
