Really enjoying AXYZ’s weekly tips, especially when it’s something recently discussed in other circles – in this case polycrystalline diamond (aka ‘synthetic diamond’) CNC bits:
The notion of PCD tooling has been a hot topic of late and with very good reason. These tools are much more expensive than the solid carbide router bits which we’ve all come to love, but is the price justified? This blog reviews PCD tooling and discusses the applications in which a PCD tool should be your tool of choice.
What is PCD?
Polycrystalline Diamond (PCD) tooling is composed of diamond particles that are sintered with a metallic binder at extreme temperatures and pressures. This manufacturing method allows diamond particles to be fused onto a carbide substrate and creates the hardest and one of the most abrasive resistant materials used in CNC router bits.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
