MDF, ie the medium-density fiberboard, is relatively easy to mill. No matter if you only want to mill one groove or a whole butterfly, you should firstly use high-quality MDF and on the other hand use only carbide cutters.
Careful work required
Medium-density fiberboard has larger differences in density. The density one plate has over another can be determined by weight.
The lighter plates are a bit looser on the inside and not pressed properly. They tear and fledder when milling therefore stronger.
Step by step Milling MDF
- MDF boards of appropriate thickness
- Milling cutter with suction device
- Carbide burs
- Ruler / template
- Pencil / highlighter
- Mouth and eye protection
1. Clamp plates
You should clamp the plates well before marking the milling lines. The markings could otherwise smudge. Ein 2. Draw Lines or Patterns
Draw all lines exactly, being careful not to blur them when working. If you want to mill intricate patterns into the MDF and are planning to have an opaque paint finish anyway, you should use a smudge-resistant highlighter for drawing.
3. Wear Mouthguard
The extremely fine particles of MDF boards can be very toxic due to the high amount of adhesive. You really should not breathe this dust. So definitely wear a mask and, if possible, safety goggles.
In addition, you should use an extraction system on your milling machine. If there is no device, simply stick the vacuum cleaner tube next to the MDF board and let it run while you work. Fräs 4. Milling of MDF boards
Depending on whether your mill or plate is to be moved, you must now guide the milling machine exactly vertically along the marked lines. But if you have a fixed cutter, you only need to push the plate through the cutter.
Tips & TricksIf you want to mill out fine patterns for decorative objects such as butterflies or flowers, then glue the stencil to the MDF board with a short crepe and immortalize the pattern with spray paint on the board.
Even if you dab the pattern with a brush, something else will always run underneath the template and you will not be able to see the milling lines later, or you may have too many of them on the workpiece.
