Cnc router components

Types of CNC Router Components

CNC (Computer Numerical Control) routers are precision tools that rely on many interchangeable parts, known as components. Some of the key CNC router components include the cutting bit, spindle, control software, and drive system.

• Cutting Bits:

CNC router bits come in various shapes and sizes. Each is designed to achieve a specific cut and to work with particular materials. They are made to accomplish tasks such as carvings, trims, engravings, or even making joints and grooves. Usually, manufacturers make router bits from high-speed steel (HSS) or carbide, which is more durable. The bits can also come in various diameters, shank sizes, and profiles.

A few common CNC routing bits include straight bits for cutting and hollow bits for making rounded carvings; V-bits used for engraving or making detailed designs; and ball-end bits that have a rounded end used for 3D contouring, among others.

• Spindle:

The spindle is one of the most crucial parts of a CNC router. It holds the cutting bit and is responsible for driving it during the routing process. Working like a motorized axle, the router bit cuts through or carves the material being worked on. Spindles come with various power ratings and designs, which may differ depending on the router’s intended use. A woodworking CNC router will likely have a different spindle from one intended to work on metal or acrylic. The common types of spindles include electric ones powered directly by an electric current from a power grid or a power provider and pneumatic ones that use compressed air.

Generally, CNC router spindles can be brushless or air-cooled. Brushless motors lack traditional brushes and are built as high-power, low-noise models. On the other hand, air-cooled spindles rely on ambient air to dissipate the heat generated during operation.

• Control Software:

Also known as CAD/CAM software, the control software is what controls the router's movement. It uses design files generated from a 3D model to direct the router on what to cut and how to do it with high precision. The software also allows the user to set different parameters like the depth and speed of the cut, and even the tool path. The software is typically easy to use and may come in a variety of applications and platforms that customers can install on their computer.

• Drive System:

The drive system is responsible for moving the spindle and router bit along predetermined paths to achieve accuracy during cutting and carving. It translates the commands given by the control software into physical movements. The drive system may use stepper motors, servos, belts, linear rails, lead screws, pulleys, or heavy-chain drag to make this possible. Whichever mechanism is used, the goal is to achieve precision and repeatability with ease.

Specification and maintenance of CNC router components

Specifications

• Work Bed Size: 1500*3000mm or other custom sizes.
• Cutting Thickness: The maximum thickness of the material that can be cut ranges from 0-200mm depending on the type of CNC router components used.
• Spindle Power: Usually between 1.5kW and 3kW for home use routers, greater than 3kW for commercial routers, and can reach as high as 30kW for professional use. It may be measured in terms of drive power, such as 1.2kWh, which is equal to 1.5kW of spindle power.
• Rotating Speed: This may be quite fast when cutting wood and other soft materials, up to tens of thousands of revolutions, but is lower when cutting harder materials, such as more than 6,000 - 20,000 rpm for a 3kW spindle.
• Applicable materials include wood, acrylic, PVC, double-color board, engineering plastics, rubber, foam, fiber, electronic materials, etc.

Maintenance

• Clean the machine: Use a clean cloth to wipe the dust and dirt on the surface of each part, paying special attention to the clean guide rail and rack. Remove the dust and debris from the machine tools, and use a blower or vacuum cleaner to blow or suck the dust in the machine tools, especially the crossways and internal parts of the nozzle.
• Lubrication: Apply appropriate lubricant to the guide rail and rack, linear bearings, and sliding blocks, ensuring they move smoothly and stably.
• Check the power supply: Check that the power supply voltage and current are normal, and ensure that the machine tools have sufficient and stable power supply.
• Check and adjust the tightness of the transmission parts: Check the tightness of belt transmission, chain transmission, etc., and adjust to the proper tightness to avoid slippage or looseness.
• Check the air system: Check the air source pressure and flow, ensuring that the air used by the machine tools is stable and sufficient.
• Check the cooling system: For CNC routers with cooling systems, check whether the coolant level is normal and whether the cooling effect is good.
• Pay attention to machine tool operation: During use, pay attention to the operating status of the machine tool, listening to whether there are abnormal sounds and promptly handling abnormal situations.

• Clean the filter: Regularly clean the air filter and water filter to ensure the purity of the air and water.
• Replace lubricating oil: Replace lubricating oil with a specific lubricating oil for machine tools at the prescribed time and perform oiling on the designated parts.
• Maintenance of electric spindle and cutter head: Electric spindle and cutter head are the key parts, which should be checked and maintained periodically. This includes cleaning the spindle and cutter head, checking for wear and tear, and timely replacement and repair.
• Electrical system maintenance: Periodic cleaning and maintenance of the electrical components, such as control boxes, electrical switches, etc., ensures that the connections and insulating properties of the electrical components are good.
