When you need a part, and it has to be made precisely to work properly, working with a machine shop that can handle CNC work is the best way to get the job done right. Using CNC machines allows the machinist to set up a program and run the part to very precise specifications that might not otherwise be possible. Used in many industries and the private sector, CNC machine work is fast becoming the standard for machine work, and with good reason.
Where to Start
With any machined part, you need to have a drawing or plan with all the details and specifications on it so the machinist can create it. CNC machine work takes this a step further and turns that drawing into a CAD drawing that is then turned into a program by an engineer. The engineer will take all your specs and information and convert them so that the CNC driving machine can precisely position holes, mill off material, or shape parts to fit your needs.
CNC Machining and Repeatability
Once your part has been created and finely turned, the final CNC program can be used to repeat the process once, twice, or even a million times if needed. This allows you to mass produce the same precision part over and over for production runs or to sell just the part to people that have a need for it.
Cost Versus Profitability
Not every business will need or can even afford the cost associated with purchasing CNC equipment and may opt to outsource the work, at least in the beginning. But as the business grows, the cost of outsourcing could become higher than purchasing the equipment and hiring the staff to produce the work in-house. Keep in mind, you will still need an engineer to write and tweak the CNC programs, but there are good operators out there that are skilled in the programming and setup of the equipment they run. So if you look hard enough, you might get both the operator and engineer in one person.
Work with CNC Equipment
CNC equipment can include milling machines, lathes, drilling and boring equipment, and even precision water-jet machines designed to cut steel and other metals with a stream of high-pressure water. Just about anything found in a machine shop can be set up as a CNC machine, and there are many manufacturers and dealers out there that can help you get the one that best fits your needs.
