CNC Machine Parts To Take The Heat
There are dozens of great ways to make prototype parts. 3D printing in many variations are all the rage these days (and for good reason), but sometimes you still need parts that can take the heat. There’s nothing like great CNC Machine prototype parts when you need something for real-life stress and abuse.
Stronger, Tougher, Better
This customer needed a part variation that was significantly stronger and more rigid. These were designed based on older parts, but more robust. Then, the CAD files were sent to one of our local favorite CNC Machine Shops, Monson Manufacturing to be made. Just send the files and wait for the note to pick them up. These are, of course, not complicated parts, but it’s always fun to get the new parts, feel the heft and know they’ll work perfect.
These particular parts are made from half-hard Stainless Steel 17-4 for strength and corrosion resistance. And, because 17-4 is reasonable to machine in the half-hard state. The previous version (designed by a different company) didn’t hold up, but these will. Roughly speaking, these clips are 4 times stronger — partly because of material choice and partly because of the engineering design changes. The final CNC machine parts could have been done in a high strength steel then heat treated for maximum strength, but that was not necessary for strength and it would take longer and cost more. Also, the choice of Stainless Steel gives the added benefit of corrosion resistance.
Nothing Like CNC Machine Parts
CNC Machine parts may be a throw back to old ways of doing things. There are some disadvantages (like cost and time to machine), but it’s still the easiest way to get parts that will stand up to real world high stress testing. As we think about functional prototypes and what we want to accomplish with them, materials come straight to the front. Then, the process of making them. In this case, full load testing will be done to prove the design, so material is a big deal. CNC Machine parts are one way to get pieces that will take the full stress and the heat.
Having a good relationship with a skilled CNC Machine Shop is important to us. That’s highlighted here with this example and these simple, but critical parts.
