how to choose bits cnc router tools.

most our customer not know how to choose the bits for our cnc routers.

Give you a detailed explanation of several categories of classified computer engraving machine engraving tool applies what pattern and apply what materials :
1 , clear bottom tool ( carbide )
Main performance : end milling
Applicable materials: organic ( acrylic ), PVC, MDF
Note : Any one engraving machine at work , we must ensure that flat plane carving , especially doing two-dimensional and three-dimensional sculpture carved carving some time in order to save often , and sloppy , and the results are either unqualified carving products . either need to manually modify
2,3 D chisel ( carbide )
Main features: three-dimensional clearance angle , chamfer
Applicable materials : organic , PVC can also be used : MDF , medium hardness wood
Note : Regardless of being carved , or anti- carving, engraving must remain flat plane ; choose the right blade width clearance angle three-dimensional sculpture, is very important , it is recommended to use small-format engraving machine blade width of not more than 22MM, large format engraving machine blade width appropriate tools can speed engraving speed .
3 , Single spiral cutter ( carbide )
Main features: two-dimensional cutting
Applicable materials: Acrylic , PVC, MDF
Features: Single design combines the advantages of a strong cutting force and chip carefree , and spiral cutting edge and ensures cutting object surface smoothness, the batch processing of PVC, MDF has a good efficiency.
4 , finished knife ( carbide )
Main features: two-dimensional carving, cutting two-dimensional , three-dimensional clearance angle
Applicable material: color plates (ABS), organic ( acrylic ) can also be used : copper, iron , aluminum, plastic and other types of metal and nonmetal .
Note: When carving metal , cooling oil should be added
To speed up the engraving speed , should be used as a wide nose . Finely carved to meet the user's requirements , the new triangular double-edged knife blade rectangular spiral cutter ( carbide )
Main features: two-dimensional cutting, carving a two-dimensional plane
Applicable materials: organic ( acrylic ), PVC is also available in: black metal
Features : For dry cutting organic boards with good corrosion resistance and wear red , spiral cutting edge and ensure the smoothness of their body surface when cutting thick plate , has a good performance it can also be used . to the processing of ferrous metals, such as iron , steel and so on.
5 , double-edged knife spiral down (carbide )
Key Features : Two-dimensional cut, two-dimensional sculpture
Applicable materials: natural wood , synthetic wood can also be used : Plastic
Features : Special wood working tools, such double-edged tool used for processing wood and synthetic wood , debris exclude convenience , the cutter body strong, durable , processing effect ( surface to ensure no glitches ) .
6 , Single straight edge tool ( carbide )
Key Features : Two-dimensional cutting
Applicable materials: cork , medium density and medium hardness of the wood . Can also be used : elastic , plastic anti-friction
Features : a combination of single-blade slotted design and geometric design , while for fast cutting debris cleared automatically .
7 , single-edged knife column (carbide )
Key Features : Two-dimensional cutting
Applicable material: color plates, plastic plates can also be used : 3MM or less thick acrylic
Note: Cut color plates, as no special requirements, you can usually use a sharp knife cut the finished product , but the knife cut easily passivated , then carved columns will be glitches single blade knife, design principles with a knife , but it is a vertical cut . without a slope, especially for mosaic designs.
8 , ball milling ( carbide )
Main performance: three-dimensional sculpture, two-dimensional cutting
Applicable materials: organic ( acrylic ) is also available in: black metal
Note : Ball milling cutter wide choice , depending on the accuracy and size of the carved surfaces , generally divided into secondary sculpture, carving can use coarse blade diameter larger , carved blade diameter should be chosen smaller tool .
9 , double-edged straight flute cutters ( carbide )
Key Features: two-dimensional sculpture, two-dimensional cutting
Applicable material: MDF , hardwood , acrylic
Features : Designed for CNC engraving MDF material and design, combined with a special carbide , hard cutter body and advanced blade geometry, durable and non-ferrous metals roughing also has a high work efficiency.
