Manufacturers rely on CNC milling to make parts and tools that require extremely exact measurements. Accuracy is key when generating surgical equipment and parts for airplane engines, or even jewelry.
Are you in an industry that uses tools, gears, or pieces that need to fit into the same space every time? Computer-controlled custom CNC milling can deliver these accurate pieces with peak uniformity.
What is CNC milling?
CNC milling is the process of keeping a certain kind of metal still as multi-point cutting tools move around it, removing material until the desired shape is left. This process is typically used to precisely create a flat surface. But by achieving vertical, crosswise and longitudinal motion, custom CNC milling can accomplish much more. It’s proven to be a very versatile method.
Types of CNC Milling
Read on to learn more about what kinds of machining can be done with CNC milling parts.
Custom CNC milling includes the ability to create a round hole in your workpiece. This works by keeping the piece still as the drillbit removes the material not needed. Only the drilled section free of debris is left. The applications here are endless, including for the electronics and automotive industry which require drilling as part of their construction.
While drilling creates a new hole where there wasn’t one before, “boring” enlarges an existing hole to exact dimensions needed. The piece being created on a milling machine remains in place. So, the boring tool must be manually adjusted to the desired size.
The benefits that come with the ability to bore holes through custom CNC milling are:
- versatility in sizing
- accurate smoothing of a hole’s interior surface
- minimizing tool deflection
The importance of a uniform production of gears that are sized and smoothed to perfection can’t be understated. CNC milling parts can achieve a quality, reliable gear cut to ensure its teeth will operate to full efficiency. Gear cutting is typically done with a hobbing machine. However, a milling machine can be equipped with a cutting tool matching the gear’s grooves to handle the cut.
Face milling is the process on a milling machine of cutting a flat surface to obtain maximum smoothness. Accuracy is ensured because the part is clamped down into place, while the CNC milling parts are exacting in its ability to machine a flat surface.
After the custom CNC milling has accomplished all its other tasks of drilling, boring, flattening or cutting, CNC milling can then provide the finishing coat. Even if machined elsewhere, CNC milling will define its features and provide that professional smoothness to the materials one sees sold in stores. Every contour, hole or slot will appear finished. It’ll be ready to go to its intended destination, such as a tool or engine.
Every one of these methods are essential when constructing tools that rely on accuracy. For example, that key or keyhole, or whatever is needed for optimal grooves, slots and smooth surfaces to operate.
