The first major advantage of CNC machining is that it improves automation, removing the need of an operator for all but a few parts of the work. CNC machines can be left unattended for hours or even days if necessary, allowing operators to focus on other tasks. This also allows for a company to retain fewer operators, thereby saving on overhead. By removing the operator, safety is also increased, since should there be a jam or other potentially dangerous machining error, the operator will not be holding the tool and the only thing damaged will be the tool itself. CNC machines can also work much faster than human machinists, since they are faster, stronger, and do not need to take breaks. They can also be run late at night, when most of the workers have gone home, since machines do not need to worry about being sleepy or getting paid overtime.

The second big advantage to CNC machining is that it produces an exact result every single time. Even the best human operator will have minor variations between finished results, whereas a CNC machine will produce exactly the same result each and every time it is run. This is very important in the modern world of standardized and interchangeable parts, where a single defective cut can make an entire machine wholly unusable. All that is necessary is for a single program to be developed and placed into the machine. Then the machine can toil away at however many work pieces are needed, producing an exact replica down to thousandths of an inch each and every time.

The third big advantage to CNC machining is the flexibility of the machine itself. While humans are much more flexible and trainable than machines, a CNC machine can be completely reprogrammed in a matter of hours to produce a completely different product. It is thus possible to refer back to old programs or install new programs when a different work piece is required. This gives CNC machines a big advantage over other machines, since they can quickly shift to producing a completely different product without the installation of many new parts or a major overhaul of key components. This also ensures that CNC machines can keep up with customer demand, since they can very quickly shift from making a part that is in surplus to a part that is lacking should a need arise.

Custom die cutting provides the right shape for any application. It is mainly used in the making of coins and medals. Also, it is used in industrial applications such as the production of polystyrene, polyurethane and polyethylene foam products. Custom die cutting offers freedom to meet exact needs. The cost of custom die cutting depends on the shape, style, and variety of the application. For custom die cutting, the process that is applied is steel rule die and precision die cutting, water-jet cutting, kiss-cutting, laser cutting and shearing. Custom die cutting needs extensive technical knowledge and a wealth of experience. Most die cutting is in fact custom, which makes the trade a highly specialized industry indeed.

Custom die cutting is also useful to create perfect custom label styles. To cut out label shapes into the label stock, custom dies are used. Products such as spacers, felt, masking devices, shims, insulators and gaskets are also created through custom die cutting. The materials used for this process include foil, thin film, foam products and paper. Custom die cutting is available for soft, non-metallic goods such as rubber, plastics, sponge, non-asbestos substances and foam. Die cut tape is another product of custom die cutting. A high degree of accuracy and premium quality are the major features of custom die cutting. Capabilities of custom die cutting include surface enhancements, slitting, coating of pressure sensitive adhesives, laminating and flat cutting. Cutting of non-metallic materials such as cloth, cork, chipboard, fiber, rubber, Teflon and rayon are available.
