Tapping fluid (coolant or lubricant) will affect tap life. “We recommend a tapping speed of 10 to 13 SFM, both turning into the tapped hole and exiting out of the tapped hole,” explained Mark Hatch, product director - taps and thread mills for Emuge Corp., West Boylston, Mass. Improper speeds can shorten tap life and even cause tap failure. ![]() Using the proper tapping speed is critical for cutting threads in titanium alloys. Very high temperatures are reached during the tapping process, resulting in the chipping of cutting edges and, therefore, reduced tap life.Īlso, titanium’s low modulus of elasticity makes the material “springy,” and the workpiece tends to close in on the tap.Įxperts offer the following tips for successfully tapping titanium alloys: Because of this, tools such as taps hold much of the generated heat directly on the cutting edge and tool face, rather than dissipating it through the workpiece, chips, and machine. Titanium is not a good conductor of heat. It is, however, the material’s unique physical and chemical properties that make it a challenging material for manufacturers. Titanium is both lightweight and strong, which makes it very appealing for many industries, such as aerospace and medical. However, with the appropriate taps, holders, and techniques, the operation still can be performed productively and accurately. Machinists typically find it much more difficult to tap titanium alloys, such as the popular 6Al-4V, than other alloyed materials. ![]()
