The CNC machining challenge.
Imagine CNC machining a product that is going to be mistreated every day.
Can you guess the product
A Hint, the product needs to be
As light as possible so it is easy to carry.
Designed to be easy to handle even when wet.
Rugged so it can be dropped and mistreated.
Machined with precision of a micron
(thinner than a sheet of paper)
Machined to able to be screwed together and unscrewed.
Finished with Anodizing that last for years.
Did YOU guess the product?
While that sounds like a strange product it is in fact a flashlight.
It has nearly every design element incorporated into the design.
CNCxpress has been producing parts for flashlight for more than 10 years.
We worked closely with the customer to develop and keep refining their designs.
With earlier designs using replaceable batteries to the latest rechargeable batteries it needed to protect the internal components while being light enough to carry for a long time.
We used many different designs on the outer skin to lighten the design while reinforcing the critical parts.
As you can imagine over the year’s we tried many designs that could not pass the extreme testing. But the result is the machining one of the leading long-lasting flashlights on the market.
What can we learn from machining a Flashlight?
It takes a few different grades of materials to ensure it will function for a long time.
The machining of the outer case requires precision machining to cut grooves to lighten the weight. While still ensuring the thickness protects the internal components.
Machining the thread must be a very tight tolerance.
To ensure it is water resistant.
It must not be so tight it can not be assembled or stop it from being opened for servicing of the components.
The finish on the outside must be able to take a lot of abuse yet at the same time be able to make it easy to grip in all conditions.
Who would have thought a humble everyday product could have so many high-tech requirements.
