![]() You can certainly use your CNC router to cut acrylic sheets, but the following tips will help you avoid irregularities or difficulties and help you maintain a smooth cut. The tools will play a huge role in determining how well you can replicate the design, regardless of how good your design is.Acrylic is a durable, clear form of plastic, and as such has different properties than metal, wood or other materials. You will have to consider the type of machine while creating your design and selecting your milling tools.Ī reliable machine and high-quality tools are a must for every maker. These milling machines can be vertical or horizontal. This ensures that the block does not move, and you can create precise shapes. There is also a table where you would clamp down the piece of metal or plastic that you are working with. The motor attached to the spindle gives enough power for the tool to rotate and create the required shapes and holes. Universal milling machines typically feature a spindle where you would attach the tools. So you have to account for the time it takes to create a smooth surface when deciding the project’s timeline. These are a single-point cutting tool that rotates in a clockwise direction. Fly cutters can help you achieve just that. You need the surface to look smooth and shiny. Fly CuttersĬreating a flat surface is often not enough for the end product. As the number of cutters increases, the precision of the face mill also increases. These milling tools completely flat surfaces and help you prepare the block for the rest of the project. Face mills are your best friends in this scenario. You will need to create a flat surface before you can start milling or drilling. The raw black of metal or plastic that you will be working with may not always have a flat surface. They are typically used for producing cylindrical parts. These tools are pipe-shaped, and their cutting surfaces are on the inside of the pipe. These pipe-shaped milling tools can perform facing, centering, and chamfering on a single pass. You may also have to use hobbing machines instead of milling machines to create gears. There are various gear cutters depending on the type of gear you want to make, such as spur gears, bevel gear, worm gear, single or double helical gear, and screw gear. ![]() If your machining project requires you to create gears, then you need to use gear cutters. Precision reamers create smooth holes of the accurate diameter, whereas non-precision reamers can enlarge a gap and create burrs. There are precision and non-precision reamers. Reamers are your best option in such scenarios as they can develop existing holes with a high level of precision. Many times, you may have to expand a pre-drilled hole to a specific diameter. You may need more of these drill bits, depending on your project. Drill bits can be classified as twist drill bits, center drill bits, and ejector drill bits. They have a long shaft and a conical end that decides the shape of the hole being drilled. Drill BitsĪs the name suggests, drill bits are used for drilling into the material. You can also classify the end mills as centered and non-centered depending on whether or not they need a pre-drilled hole to start cutting. There are various types of end mills depending on the shape of the mill and their functionality, such as flat end mills, bullnose mills, ball nose ends, V-bit, roughing bit, and flat bit. They have sharp cutting flutes that can easily remove materials. End MillsĮnd mills are typically used for cutting away large portions of materials. However, here are some that are most commonly used for manufacturing parts using the CNC machine. And since each project is different, the milling tools will also vary from project to project. The CNC machine then uses various milling tools and a CAD design to remove parts from the block to create multiple shapes, grooves, holes, etc.Īs you can see, the milling tools play a huge role in determining the result. The process starts with a raw block of metal or plastic. Essential CNC Milling Tools for Your First Machining ProjectĬNC machining is used to manufacture precision parts for various types of machinery and types of equipment. ![]() But what are the must-have CNC milling tools for your first machining project? Read on to find out. After a lot of time spent honing your skills, learning about the various tools, and becoming well-versed with operating the Computer Numeric Control or CNC machine, it is now time to put all that knowledge into use.
