  • Extra Extra Long End Mills-Square End-Carbide-General Purpose

    An extra extra long length square end mill is the longest flute length, single end, general purpose mill, where the corners are sharp and generate a 90° corner. The term "general purpose" means that the mills are manufactured with a 30° helix angle, have a primary and secondary clearance angle on the OD's, and are center cutting. They can be used for plunging, grooving, side milling, face ...

  • Reducing Chatter with 'Weird' End Mills in CNC Machining ...

     · Chatter happens when the harmonics of an end mill and a workpiece are at different frequencies, with these two objects hitting together, resulting in noise and damage. End mills have been designed to avoid or minimize chatter through variable helix/lead and pitch. Variable helix/lead with angle changes along a flute have also been used.
