Frequently Asked Questions
What is the cutting speed of MDF CNC?
The MDF CNC router cutting speeds may vary depending on a variety of factors, including the specific machine, spindle speed, feed rate, and complexity of the cutting operation. Typically, cutting speed is measured in terms of the distance the CNC router travels per minute (in inches or millimeters per minute).
For MDF, typical cutting speeds can range from a few inches per minute for intricate and detailed cuts to hundreds of inches per minute for rough cuts. The spindle speed represents the rotation speed of the cutting tool and is a key factor affecting the cutting speed. Higher spindle speeds combined with appropriate feed rates allow for faster cutting speeds. Additionally, it is crucial to strike a balance between cutting speed and cut quality.

- Tool path simulation: Before making the actual cut, the tool path needs to be simulated in the CNC software. This includes selecting a cutting strategy, specifying tool details, and determining the depth of the cut to help identify any potential issues and ensure the cutting path is consistent with your design.
- Tool changes (if applicable): If your project involves multiple tools, the CNC router may need to change tools. Make sure the necessary tools are loaded into the machine and the tool-changing process is programmed in the CNC software.
- Run the CNC program: Start the CNC router and monitor the initial number of passes to ensure the tool is cutting as expected. If necessary, adjust the feed rate, spindle speed, and depth of cut.
- Monitor the cutting process: Please pay close attention when the CNC router is performing the cutting process. Check for any issues and be prepared to resolve them promptly.
- Dust collection: Use a dust collection system to minimize dust generation. MDF produces fine particles that can be harmful if not properly controlled.
- Check the finished cut: After the CNC router completes the cutting process, check the accuracy and quality of the finished cut. Grind or polish edges as needed for a polished finish.
- Post-processing: After the CNC router has finished cutting, the finished project is removed from the machine. Sand edges or surfaces as needed to achieve the desired finish.
Does MDF dull router bits?
Yes, MDF can cause router bits to dull over time. MDF is made of wood fibers and resin bonded under high pressure and temperature. While it is a versatile material for woodworking and CNC routing due to its uniform density and smooth surface, it can be abrasive, causing the router bits to wear out faster.
When cutting MDF, several factors can cause the router bit to dull relatively quickly:
- Abrasiveness: The fine particles generated during the cutting process may be abrasive and gradually wear away the cutting edge of the router bit.
- Adhesives: MDF contains adhesives that can cause degradation of cutting tools when heated during cutting.
- High Density: Due to their increased density, certain types of MDF (especially high-density variants) are more difficult for router bits.
- High resin content: The resin in MDF can become sticky and cause material to build up on the router bit’s cutting edge. This accumulation can affect the performance of the bit and cause passivation.
- Temperature rise: Friction generated during the cutting process, especially if the router bit is not properly lubricated or cooled, may cause a temperature rise. The high temperature will accelerate the passivation of the router bit.
- Use carbide router bits: Carbide router bits are generally more durable than high-speed steel router bits and better suited to MDF’s abrasive nature.
- Reduce speed and feed rate: Adjusting the speed and feed rate of the CNC router can help manage heat build-up and reduce wear on the router bits.
- Check your drill bits frequently: Check your router bit regularly for signs of wear, such as blunt edges or chips. Replace the router bit as needed to maintain cutting accuracy.
- Dust removal: Use a dust removal system to remove dust and particles from MDF during cutting, which helps prevent debris from building up on the milling cutter.
- Cooling and Lubrication: Consider cutting fluids or lubricants to reduce friction and heat during routing, which can help extend tool life.
What RPM is needed for CNC cutting MDF?
The recommended spindle speed (measured in revolutions per minute, or RPM) for a CNC router to cut medium-density fiberboard (MDF) may vary depending on factors such as router bit type, bit diameter, specific cutting operation, and characteristics of MDF in use. However, a general guideline is to use a low to mid-range spindle speed for cutting MDF.
As a starting point, you might consider a spindle speed in the 12,000 to 18,000 RPM range when cutting MDF with a standard mill. Smaller diameter drill bits can tolerate higher speeds, while larger diameter drill bits may require slower speeds to avoid excessive heat build-up.
Here are some general tips:
- Router bitdiameter: Smaller diameter drill bits can generally handle higher RPMs, while larger diameter drill bits may require lower RPMs to prevent overheating.
- Cutting depth: Adjust the cutting depth according to the function of the CNC router and the type of cutting operation. It is generally recommended to perform multiple passes with gradually increasing depth of cut.
- Manufacturer recommendations: Refer to the recommendations provided by the CNC router and the manufacturer of the milling cutter you are using. These guidelines often include optimal rpm settings for various materials and drill bit types.
- Material properties: The density and composition of MDF affect ideal cutting parameters. Softer MDF may require different speeds than denser variants.
- Test cuts: Making test cuts on MDF scraps can help you fine-tune your cutting parameters to ensure the best results for your specific setup.
