  1. For engraving fine text pattern, small cutting tools with small angle and small nose shall be used; For engraving large text pattern, cutting tools with big angle and big nose should be chosen in the case that it doesn’t affect the cutting accuracy. For carving machining path designing, try to use the cutting tools with maximum cutting angle and tip, in order to improve carving efficiency. The cutting angle and tip shall be as big as possible for carving hard material.

 

2. Low-power spindle motor (with small clamp) should use a small shank tools (3.175 mm, 4.0 mm), and cutting speed should not be too fast to maintain minimal resistance in high-speed milling, in order to get the best cutting results; High power motor can use a large shank diameter engraving tool to increase speed.

 

3. Common appropriate carving knives blade length choice is to add 2-3MM on the basis of the processing sheet thickness. During cutting acrylic and when the motor speed 18000-24000 rev / min, the cutting tools with long blade length should not be used to process hard material.

 

4. For the double-edged combination blade knives with carved lens, the blade diameter and choice length choice is: Blade length = plate thickness – bevel depth, blade diameter is preferably more than twice the length of the blade;

 

5. Except for its own quality problem, frequent tool breaking is related with your carving setting habit, rail and motor precision, plate material hardness, well as fixtures and so on.in addition to the quality of a relationship with the tool.
