Types of cheap CNC routers

A CNC or computer numerically controlled router is a carving tool used in the machinery industry for automated cutting. These devices are often used in woodworking but can also be excellent for cutting other materials like plastic, foam, stone, fiberglass, and aluminum.

CNC routers come in various configurations and types, depending on the design of the device and the type of work it is supposed to support.

• CNC wood router :This device is the standard CNC router designed primarily for wood. It has a large cutting area and uses bits of various shapes and sizes to cut, carve, and engrave wooden workpieces. Usually, a cheap CNC wood router will come in two main types, the desktop and the one in a frame. A desktop wood router is smaller and more suitable for home workshops and budgets. In contrast, a CNC router in a frame is larger and more powerful, making it more suitable for commercial use. Frameless CNC routers, like the XWorks, use a CNC frame to hold the technology, allowing it to cut larger pieces more accurately.
• Plasma CNC router machine :As the name suggests, this device uses plasma to cut through metal workpieces. A Plasma CNC machine works by using electric arcs to hasten the ionized gas in the torch and heat the metal until it is melt-through. These routers are excellent for making large cuts on thick metal workpieces that may even be up to 200mm.
• Laser CNC router machine : This device uses a laser beam to cut, etch, or engrave various materials like wood, acrylic, metal, leather, and more. Laser CNC routers offer high precision and clean cuts with minimal material distortion. They are suitable for detailed engraving and cutting tasks on different materials. A laser CNC machine may feature a fiber or CO2 laser. The CO2 option is better for cutting non-metal materials, while the fiber option is great for metal materials.
• Oxi-fuel CNC router machine:Also known as oxygen-fuel CNC routers, these devices use a combination of oxygen and propane or natural gas to create a flame that cuts through metal. Oxi-fuel CNC routers are commonly used for cutting thick metal plates and are suitable for heavy-duty industrial applications. These devices aren’t as popular because they are less precise than their plasma counterparts.

CNC routers can also be categorized by the way the router is controlled and guided. These include:

• Gantries:These routers have vertical support columns that hold horizontal beams over the workspace. Large pieces of work are better supported with this design.
• Bridge:These routers have horizontal members that are moved along vertical frames. They are used for large workpieces that require a lot of cut depth and are similar to gantries.
• Tables:These have a moving platform that shifts across a fixed router. It is ideal for smaller pieces with not so much of a heavy workload.

Specifications & Maintenance

• Working Area:

  A cheap CNC router’s working area measures the largest size of material it can work with. For instance, a router with a 300*400mm working area can easily cut or engrave a material that is 300mm wide and 400mm long.

• Spindle Power:

  This measures the level of power the router control's cutting motion. Cheap CNC routers usually have spindle power of about 150-300W. This power is enough to perform light cutting tasks on soft materials.

• Control Software:

  The software used to control cheap CNC routers varies widely. It often ranges from simple programs to more advanced ones. Some of the common software include Artcam, Ucancam, etc.

• Frame Material:

  This refers to the material used in constructing the router's frame. Most cheap CNC routers have aluminum or steel frames. More expensive models are made with a combination of alloys and metals for sturdiness and stability during operations.

• Interface:

  A cheap CNC router interface allows the user to manage and oversee tasks the machine carries out. How user-friendly an interface is will determine the user's ability to handle the machine with little or no training.

Proper maintenance is crucial to the optimal performance of a CNC machine. It also prolongs the lifespan of the device. Here are some maintenance tips to consider:

• Routine Lubrication: Cheap CNC machines usually have multiple moving parts. Lack of lubrication can cause premature wear or frequent breakdowns. Routine lubrication helps to minimize friction.
• Scheduled Cleaning: Dust buildup can happen naturally during the machining process. This buildup can negatively impact the performance of the machine. Scheduled cleaning helps to prevent dust buildup from affecting the routing machine's performance.
• Monitor Cutting Tools: Each cheap CNC router tool has its own lifespan. Constant usage wears them out and affects the quality of the cut. Therefore, it's important to monitor the state of these cutting tools and replace them when necessary.
