Good afternoon, I have material that I've not worked with yet and am looking for input. The material is Niobium and Tantalum. After doing some research I found that there are some health effects caused by these materials. Should I be concerned? Also, how do these materials machine? Any comments, advice, input, or questions are wanted.

Machining Teflon. PTFE's density and softness make it deceptively easy to machine, and in grade, has a temperature range from -450°F to +500°F (-267.7°C to +260°C). Teflon has low strength when compared to materials like Nylon, which has almost two to three times the tensile strength of Teflon. You'll want to use extremely sharp ...

Milling is very similar to drilling and cutting, and CNC milling machines perform both of these operations at a variety of angles. CNC milling is a highly customizable automated machining process. Equipment used for this technique rely on computerized controls and specialized cutting tools to create the desired product by progressively removing material from the workpiece.

CNC milling is manufacturing where computers are used to operate the drilling machine to shape the material into the desired object. It does this using a milling cutter attached to rotating spindles, which cut into the material of your choice. CNC stands for "computer numerical control", meaning each part of the device follows instructions from […]

Machining Polyproylene . Annealing Polypropylene. Due to its low annealing temperature, PP, like any polymer under heat and pressure, has a tendency to deform during machining. The annealing process at AIP greatly reduces the chances of these stresses occurring from the heat generated during machining PP and other polymers.

Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.

Materials, coatings and geometry are the three elements in tool design that interrelate to minimize these concerns. If these three elements do not work together, successful high-speed milling is not possible. It is imperative to understand all three of these elements in order to be successful in the high-speed machining of aluminum.

The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of pre-shaped material that is secured to the fixture, which itself is attached to a platform inside the milling machine. The cutter is a cutting tool with sharp teeth that is also secured in the milling machine and rotates at high speeds.
