Technological tips for machining titanium fasteners

Use blades with positive geometry to reduce cutting forces, cutting heat and workpiece deformation; keep the blade edge sharp. Blunt tools are the cause of heat buildup and wear, which can easily lead to tool failure.

Maintain a constant feed to avoid hardening of the workpiece. The tool should always be in feed during the cutting process. The radial cutting amount ae should be 30% of the radius during milling.

Use high-pressure and high-flow cutting fluid to ensure the thermal stability of the machining process and prevent surface degeneration and tool damage due to excessive temperature. titanium foil grade 5 / titanium metric screw / Gr2 Pure Titanium Plate

Process titanium alloys in the softest state as much as possible, because the material becomes more difficult to process after hardening, and heat treatment increases the strength of the material.

Use a large tip radius or chamfer to cut in and put as much of the blade into the cutting as possible. This can reduce cutting forces and heat at each point and prevent local damage. When milling titanium alloys, the cutting speed has the greatest impact on tool life vc among all cutting parameters, followed by radial cutting amount (milling depth).
