A honeycomb structure serves as an excellent gas flow seal and a sacial wear-surface to rotating turbine blades in high-temperature turbines. Achieving the ideal honeycomb construction requires careful attention to the amount and placement of brazing filler metal and brazing time and temperature. Honeycomb structures, one of nature's unique …

Indy Honeycomb's proactive mindset is recently demonstrated by our decision to pursue the NADCAP accreditation. We will be focusing on our Spark Erosion Grinding (SEG) process for small cell applications, primarily engine seal honeycomb.

Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes, separated by a …

Spark Erosion Service. The Sink EDM process enables us to produce cavities in materials such as hardened tool steel, tungsten carbide, aluminium, inconel, titanium and other exoctic alloys with exceptional accuracy on our Chmer CM545+75PZ ZNC and Eurospark 1000 Sink EDM machines – in fact as long as the metal is conductive it can be eroded ...

The waveform of each spark is automatically monitored and categorized based on material being eroded, erosion gap distance and other factors essential to optimal erosion process. The generator can then dynamically adapt the energy level of each-and-every spark (current, voltage, duration and time-off) to suit the material being eroded.

Two primary purposes for using honeycomb for rotor-blade tip seals (rubbing seals, abradable seals, etc.) are: (1) to provide a gas-path seal to prevent hot engine gases from getting around the ends of the turbine rotor blades, and (2) to simultaneously provide a sacial surface against which the rapidly rotating blades will rub.

The main advantages of using an orbital welding machine is the consistent quality of the weld which makes certifying welds a lot easier and quicker as testing finished welds are kept to a minimum. This is made possible by the repeatability of the process as computer controlled parameters are used to complete the same weld multiple times.
