CNC Milling Engraving Machine VS Laser Engraving: The Main Differences

Process
CNC milling engraving machine is a subtractive process that removes material from a surface to create the desired shape. It is typically done with a CNC router machine, which uses a cutting tool to cut away material along predetermined paths to create the desired shape or design. Laser engraving is a non-contact process that uses a focused beam of light to etch a design onto a surface. CNC laser engravers use a computer-controlled laser beam to vaporize the material in a pattern that precisely replicates the programmed design.

Accessories
CNC milling engraving machine are equipped with a range of accessories to keep the machine running efficiently and safely. Common accessories include diamond engraving bit holders, toggle clamps, carbide cutting tools, spindle-mounted dusters, and suction pumps.These accessories help keep the work area clean by removing dust and debris with a spindle-mounted dust shoe and suction pump. Laser engraving machines require additional accessories to enable them to engrave on curved surfaces. These accessories include a rotary attachment, air assist system, exhaust system, and safety goggles.

Design phase
The main difference between CNC milling engraving machine and laser engraving is the type of file required during the design phase. CNC engraving requires a CAD file while laser engraving requires a vector or raster file.

Materials
CNC milling engraving machine is commonly employed on metals, wood, and some plastics, providing a high-precision output that can create unique items. Not only that, CNC engraving can be carried out on various materials such as aluminum, brass, and copper. Laser engraving is a more versatile option for a much wider range of materials. Wood, plastics, glass, anodized aluminum, and certain types of stone can all be engraved with a laser engraving machine.

Precision
The accuracy of CNC milling engraving machine can vary depending on the type of machine and the process used.Standard CNC milling engraving machine can provide an accuracy of about 0.001" to 0.005", which is suitable for most manufacturing applications. The accuracy of laser engraving machines depends largely on the quality of the laser beams and the materials used. High-quality laser beams and specialized materials can help increase the accuracy of the laser engraving process.

How to Choose a Tool For CNC Milling Engraving Machine?

For high-density board or solid wood processing, it is recommended to use a spine knife.

For multi-layer board or plywood processing, double-edged straight groove milling cutter is recommended. For acrylic mirror processing, diamond processing tools are recommended.

For rough processing particle board processing, it is recommended to use multiple milling cutters.

For cork, density board, log, PVC board, acrylic large deep relief processing, single-edged spiral ball end milling cutter is recommended.

For cutting aluminum, it is recommended to use a special milling cutter for single-edged aluminum. Because the single-edge special aluminum milling cutter does not stick to the tool during processing, the speed is high and the efficiency is high.

How to Use The tools of CNC Milling Engraving Machine correctly?

The size of the jacket should be appropriate. Jackets with cross-sections, not round, worn, and tapered in the inner hole must not be selected, otherwise it will cause a sensation in the handle and fail to make aspirations.

The handle should touch the jacket gently, and the handle should be pierced firmly into the jacket and tightened. If the jacket has been used for a long time, the inner hole is deformed, it is necessary to replace the jacket immediately.

Always check the patience of the tool. If you use it bluntly, please replace it immediately. If you continue to use it, it will not only perform poorly, but it will also cause the knife to break.

When using woodworking CNC engraving machine, pay attention to that the thickness of the processed material cannot exceed the thickness that the cutting edge can cut, otherwise the knife will be broken or the engraving effect will be unsatisfactory.

For the cutting of different materials, it is necessary to select different tools and adjust the cutting speed reasonably.

During the working process of the engraving machine, the high-speed rotating knives are very sharp. Pay attention to the body, clothes and hair not close to the objects in the work to prevent accidents.

FAQ

Q: Can a CNC router engrave ?

A: Almost any CNC machine can be used as an engraving machine, whether that's a CNC Router or a desktop CNC machine, although there are a few features that can make a particular machine more suitable for engraving. Ideally, a CNC machine used for engraving would include a high-speed spindle.

Q: How does a CNC engraver work ?

A: CCNC engraving is a subtractive process that removes material from a surface to create the desired shape. It is typically done with a CNC (Computer Numerical Control) router machine, which uses a cutting tool to cut away material along predetermined paths to create the desired shape or design.

Q: What are the limitations of CNC milling ?

A: The general limitations of CNC Milling are prototype size, axis movement, and drill bit size. The size and shape limitations will vary by the machine used.

Q: Can a CNC machine engrave acrylic ?

A: CNC acrylic engraving is the process of adding a design, symbol, artwork or marking onto an acrylic product. The automated equipment can engrave something quickly and accurately, so it will look identical each time it is done.
