Can you tap Macor?
Relieve the drill flutes constantly, especially for small diameter holes. It is possible to ultrasonically drill MACOR®. Tapping. Make the clearance hole one size larger than that recommended for metal (typically 0.1–0.2mm larger).
Is ceramic machinable?
The vast majority of technical ceramics are non-machinable and can only be processed with the use of diamond tooling once sintered, as the material is nearly as hard as diamond. In sacrificing the super power of hardness, machinable ceramics balance this loss with a range of other benefits.
Is Macor brittle?
Setting Up. MACOR machinable glass ceramic is not resilient so, when small or delicate pieces are being machined, make sure that the load is uniformly distributed. Remember, you are machining a brittle material so always avoid physical shock.
How is Macor made?
Macor is made up of fluorphlogopite mica in a borosilicate glass matrix. Its composition is roughly: 46% silica (SiO2), 17% magnesium oxide (MgO), 16% aluminium oxide (Al2O3), 10% potassium oxide (K2O), 7% boron trioxide (B2O3), 4% fluorine (F).
What is alumina used for in ceramics?
Alumina ceramic (Aluminum Oxide or Al2O3) is an excellent electrical insulator and one of the most widely used advanced ceramic materials. Alumina components are used in a wide range of applications such as electronics, pump components and automotive sensors.
Can alumina be machined?
The finishing of alumina ceramics can be done using laser machining, precision grinding, or other processes. However, alumina injection molding remains the most suitable alumina manufacturing process due to various possibilities for component design.
