Advertising engraving machine tool selection and use?
1, advertising engraving machine tool selection:
(1) Flat-bottomed knife
W1: indicates the tool search shank diameter of the tool. The common shank diameter is ∮3.175, ∮4, ∮6, root.
Set as needed.
W2: Indicates the width of the tool tip. It directly affects the engraving effect. It should be as accurate as possible when setting. You can take a high-precision ruler for general reference.
A: Half of the angle between the two sides of the tip portion. If it is a 30° tool, A is set to 15, and so on.
Engravable materials: two-color board, PVC board, plexiglass, ABS board, etc.
Cuttable material: two-color board, ABS board.
Knife principle: use W2 or A small knife when carving small characters, use large knife as much as possible to increase the processing speed; the tool selection is based on the narrowest stroke; if necessary, without affecting the font effect, the available nodes Edit and modify the strokes to facilitate the path of the oversized knife; the carving badge is commonly used for 30° cutters; if the word is too small, it can be replaced with a single line and then cut the path with “cut”.
(2) Straight knife (column knife)
W1: The width of the front end of the cutting edge. The common width is 2MM, 1.5MM. Generally, it is slightly smaller when it is set. Because the front end is convenient for chip removal, the side edge is repaired, so the actual width is slightly smaller.
H1: The length of the cutting edge of the tool, the height of the material to be cut should be lower than the length of the blade. Generally, the H1 is set to about 5 mm.
Engravable materials: two-color board, PVC board, plexiglass, ABS board, etc.
Cuttable material: two-color board, ABS board.
Therefore, the kind of knives are mostly used for large-scale carving on the department cards, so it is also called the department card knives, but the engraving effect is slightly inferior to the flat-bottom knives of the same width. The edge of the material it cuts is a straight edge, and the edge of the material cut by the flat-bottomed knife has a beveled edge. The degree of tilt depends on the angle of the tool. The angle is large and the edge slope is larger.
(3) Milling cutter
W1: the width of the front end of the tool, the diameter of the commonly used shank is ∮3.175, ∮4, ∮6; if the thickness of the cutting material is less than 10MM, when using ∮3.175 knives to cut the word to be deformed, sometimes using the shank diameter Change from ∮3.175 to a shank tool with a ∮2 or ∮1.5 at the front end.
H1: the length of the blade, the thickness of the cutting material should be lower than the length of the blade. Generally, H1 is divided into the following types according to the thickness of the material (2 mm more than the cutting material, which is convenient for chip removal).
12mm: Cut 10MM and below materials
17mm: cut 15MM material
22mm: cut 20MM material (PVC is more than 3.175; acrylic is used ∮ 4)
Engravable materials: PVC board, plexiglass, wood board, etc.
Cuttable materials: PVC board, plexiglass, wood board, etc.
Knife principle: It is not recommended to cut 10MM and below materials with 22mm cutter, which may lead to broken knife; when there is no 22mm cutter, it is necessary to cut 20MM material, and can temporarily use 17mm cutter to realize by layer cutting.
(4) Three-dimensional shaped knife
Because this kind of tool is different from the common engraving tools that we need to directly grind out the work with an alloy shank material, we weld the various shapes of the knives under the shank of ∮6 by special welding process. The head is directly used for engraving of various special shapes, so it is also called a big knife.
W1: The diameter of the big knife under the shank is randomly matched to 32mm; there is also a smaller one for cutting small three-dimensional characters.
A: Half of the angle between the two sides of the tip part. Because the 90° tool is randomly matched, A is set to 45 (similar to a flat-bottomed knife)
W2: The width of the tool tip. Because the specific path is calculated when the three-dimensional path is calculated, it has no meaning. Usually 0.1 or 0.2 is required.
Tool use: 3D clear corner words (calculate path with "3D" function) and reversed beveled back crystal card.
2, advertising engraving machine use: the main purpose of advertising engraving machine is carving and cutting.
