The Difference Between CNC Milling And CNC Drilling
CNC milling and drilling are both subtractive technologies, which require a larger portion of materials to reduce it down to the finished product, the technologies aren't mutually exclusive, and their use largely depends on what needs to be done. The main difference between CNC milling and CNC drilling is the functionality, motion, and desired result – for projects that require holes only, then drilling is the most appropriate option to choose, but if the design is more complex, and requires different shapes or surfaces, then a CNC drilling service is the best choice.
CNC drills are used to press through the material and create precision holes from a flat surface, whereas milling cuts in from varying axis' and can create a variety of cut-out shapes within the material due to their movability along these axes. Milling machines can allow you to use drill bits to cut up and down but drilling machines don't allow you to cut horizontally with milling bits. Most CNC milling machines will have built-in tables to secure the materials and project in place, but this isn't always the case with CNC drilling machines – they might come with a vice, which can make them more flexible in setting up in an area where space restrictions are an issue. Drilling machines also have an advantage in often being considerably less bulky than milling machines, although neither is particularly suited for mobile operations.
There are pros and cons to both technologies, and when deciding on whether a CNC drilling or Milling machine is most appropriate, it's going to largely depend on the type of work it's being procured to handle, the amount of available space to set it up, the speed and quality of the computing interface and available connections (such as internet speed), and the budgetary restrictions of the company. It's also important to note that many CNC drilling service can work in conjunction with each other (beyond just the mill and drill) and having space and budget to extend into other areas and machines, can vastly increase the productive and creative options available.
