CNC stands for Computer Numerated Control. This technology allows part fabrication to be done almost completely automatically, thus eliminating the human element. Even with the largest of component machining designs, including crankshafts, camshafts, valves, bearings, or transmission parts, it’s commonplace today to accomplish fast, reliable and even completely automatic part fabrication with CNC machinery. The most popular CNC machinery is called the CNC Router. Used in CNC milling machines, routers make it possible for designers to precisely machined both small and large components.
The CNC grinding machine and router CNC router work in tandem to provide precision work. The CNC router is the CNC machine that does the work, leaving the user of the CNC grinding machine to simply look after the rest. In a sense, these CNC grinding machines and routers are designed to co-exist. They allow users to focus on their design concepts and let the CNC grinding machine do all the work.
For example, consider the high-quality stamped metal workpiece we used to design in our shop. Each piece was carefully formed from a sheet of high-quality steel to ensure strength and a desirable finish. To produce each unique piece, we used high-speed lathes on our CNC grinding machines. We then designed a system to securely mount the individual workpieces onto the lathe. When finished, each workpiece would have a unique, high-quality finish.
But despite all of the automation and design capabilities built into our CNC grinder, there were still parts of our design that required manual input from the operator. Often, we would need to adjust a weld or apply some finishing touches to a weld. Although we could simply turn the workpiece around and perform these tasks, manually doing these final tasks on a CNC grinding machine could take much longer than doing them manually using our CNC grinding machines alone. This added extra time and effort made our work quality less consistent and sometimes resulted in having to backtrack and start the process from the beginning.
There are some instances where a piece may need to be moved during the manufacturing process. If the item is heavy or large, this may lead to additional parts needing to be added to the machine during the grinding process. In addition, because we used CNC grinding machines to perform these tasks, any additional parts that we added would need to be aligned properly using CNC machines before they were added to the main body. Because we did not use our hands during this process, this often resulted in inaccurate, incomplete, or wrong alignments.
When purchasing CNC grinders and machines, you should also consider whether the CNC machine will be used for producing prototypes as well as finished products. Although prototypes can often be used with standard CNC grinder machines, it is possible that using these types of machines will be more accurate and efficient than using standard CNC grinders and machines. This is particularly true if your prototype will need to be produced in a limited amount of time or if it will need to have several parts produced at once. Using standard CNC machines with prototype production may lead to errors that could potentially cost the company or prototype maker money.
