Q9: Acrylic is not cut cleanly.
A: Resins, such as acrylic, will easily melt if the rotating cutter comes in contact with the same location.
Therefore, increase the X and Y speeds and reduce the Z cutting-in amount.
In addition, if MODELA Player 4 CAM software is used, the cutting parameters for each material can be checked
with [Customer Parameters] on the Options menu.
If the cutter is blunt, the material will easily melt; therefore, be sure to use a new cutter.
Q10: The cutting results are not clean.
A: Check the following.
- Are the cutting parameters optimal?
The optimal cutting parameters are determined by the hardness of the material, the feed rate, the spindle
revolution, the cutting-in amount and the capabilities of the tool. Adjust the parameters little by little while
checking the cutting results.
- Is the cutter firmly secured in place?
Tighten the mounting screw to firmly secure the cutter in place.
- Is the blade of the cutter worn?
If the tip of the cutter is worn, replace the tool with a new one.
Q11: What is the black soot attached to the spindle motor?
A: The spindle motor has a motor brush inside and the brush is abraded away after a substantial operating time.
The abraded portion makes up the soot and is ejected through the hole of the motor. It has no problem in
practical use.
Q12: The taper of the cutter contacts vertical wall of the workpiece
and interferes with cutting. How can I deal with it?
A: The genuine cutter makes a sudden stop due to an impact induced when it touches the vertical wall of the
workpiece with a height of 6 mm or more.
The wall height should not exceed the effective cutting length of the cutter.
Q13: How can I remove the cutter from the collet?
A: First remove the set screw secured at the collet and withdraw the cutter using pliers.
Please wear gloves before removing the cutter and be very careful not to get injured.
