Green Machining Ceramics

Products and services offered.

Green machining ceramics. We are experienced in machining aluminum oxide silicon nitride silicon carbide stabilized zirconia aluminum nitride iron oxide quartz sapphire ruby ceramic composites and other high tech ceramic materials. The green machining process covers clamping and handling techniques suitable for ceramics the application of ultra hard high performance cutting materials as well as the consequent use of cnc basis programs. This is the method to manufacture ceramic prototypes. Common metalworking machines are used to machine the part in this soft condition as greater material removal rates are possible than by post sintering operations such as diamond grinding.

For example narrow bore patterns are possible with green machining that would otherwise generate high costs in the primary shaping process. Machined ceramics is a precision ceramic machining company with many unique capabilities. After the primary shaping process the geometry can be further trimmed. Green machining means modifying components before the sintering process.

It was a belt driven fully automated computer controlled milling machine which could be operated at variable rpm of 3000 12 000 with maximum x y and z speed of 14 mm s. For ceramics green machining is used to add detail to some isostatically pressed parts before thermal treatment. A bench top cnc milling machine mdx 650 roland dg ltd japan was used. Green machining of ceramics is done whenever possible since the machining of ceramics after firing is very costly.

For metal parts details might be added after thermal treatment by traditional machining operations. Cnc mills and cnc lathes drilling equipment cut off saws surface grinders rotary grinders as well as many machines that have. Green body machining is done using tool steel cutters and conventional methods. Similar to the classical processing of ceramics there is green machining and white machining in fibre reinforced ceramics too.

For this task we recommend the use of our dip diamond coated tools with our dip3s coating a nano crystalline coating. The point at which machining occurs determines the specific process used. Green machining this technique is commonly applied to as pressed parts which are still in a chalky condition. Machining green bodies certain features can be machined into a green body or a bisque fired ceramic part before firing it to its full density.

The machining of technical ceramics in an unfired state is called quite simply green machining and in the case of some of the hardest ceramics it is a far more economical route to take than post machining after firing. The machining centers found in our plant are very similar to those found in standard machine shops. Cnc green machining of ceramics.
