How many knives does the advertising engraving machine have?

The advertising engraving machine has roughly four kinds of tools, namely a flat-bottomed sharp knife, a straight knife (column knife), a milling cutter, and a three-dimensional shaped knife.

How many kinds of knives are there for advertising engraving machines?

1, flat-bottomed knife:

W1: indicates the diameter of the tool holder. The common tool holder 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.

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.

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).

4, three-dimensional shaped knife:

W1: The diameter of the big knife under the shank is randomly matched to 32mm; there is also a smaller one for cutting.

Cut small three-dimensional words.

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.

How many knives are used in advertising engraving machines?

1. Flat-bottom sharp knife: 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 subject to the narrowest stroke; if necessary, without affecting the font effect, available The node edits and modifies the strokes to facilitate the path of the oversized knife; the engraving badge is commonly used for 30° knives; if the word is too small, it can be replaced with a single line and then “cut” to calculate the path.

2, straight knife (column knife): Therefore, the kind of tool is mostly used for large-scale carving on the department card, so it is also called the department card knife, but the engraving effect is slightly inferior to the flat-bottom knife 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: 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.

12mm: Cut 10MM and below materials

17mm: cut 15MM material

22mm: cut 20MM material (PVC is more than 3.175; acrylic is used ∮ 4)

4. Three-dimensional shaped cutter: Because this kind of cutter is different from our common ones, it uses a single alloy shank material to directly grind the various engraving tools required for the work, but it is welded under the shank of ∮6 through a special welding process. The cutter heads in various shapes are directly used for engraving of various special shapes, so they are also called big-headed knives.

What are the scopes of several types of knives for advertising engraving machines?

1, flat-bottomed knife:

Engravable materials: two-color board, PVC board, plexiglass, ABS board, etc.

Cuttable material: two-color board, ABS board.

2, straight knife (column knife):

Engravable materials: two-color board, PVC board, plexiglass, ABS board, etc.

Cuttable material: two-color board, ABS board.

3, milling cutter:

Engravable materials: PVC board, plexiglass, wood board, etc.

Cuttable materials: PVC board, plexiglass, wood board, etc.

4, three-dimensional shaped knife: three-dimensional clear angle words (using the "3D" function to calculate the path) and the back oblique edge of the crystal card.

What are the precautions for the advertising engraving machine?

1. When cleaning, use a gasoline or WD40 cleaning agent to clean the chuck and pressure cap.

2. Put the chuck into the pressure cap, otherwise the cutter is not easy to install. If the chuck is not clamped in the pressure cap, the chuck will be caught in the motor shaft when the knife is unloaded.

3. Before clamping, pay attention to whether the chuck matches the selected tool, otherwise the tool cannot be tightened.

4. When clamping the tool, the part of the tool that protrudes out of the chuck should not be too long, otherwise it will easily generate vibration during the machining process, which will affect the processing quality of the workpiece surface.

5. When changing the tool, it must ensure that the spindle speed is zero, that is, the tool can be dismantled when the spindle is stopped, otherwise serious personal injury accidents may occur.

6. If you use the presser foot to engrave, you must use a vacuum cleaner to clean the dust on the presser foot and the spindle, and then clamp the tool.

7. In the process of screwing up the cap upwards, be sure to press the cap on the positive rotor thread, first screw it in place with no effort.

8. When unloading the knife, use an air gun to clean the dust on the pressure cap and the rotor shaft before unloading the knife.

How can the advertising engraving machine be used without damaging the tool?

1. Whether the engraving machining allowance is reasonable, whether there is a stepped margin, so that there will be a change in the cutting force caused by the vibration during the machining, resulting in the broken knife, so it is necessary to increase the semi-finishing. The other is whether the amount of knife is too large.

2. Whether the power supply provided by the engraving machine is stable or not, the unstable power supply will also cause the engraving machine to break the knife.

3, check whether the priority mode of the advertising engraving machine is correct, it directly affects the starting speed of the machine tool, the higher the starting speed, the more likely it is to generate vibration, which will easily lead to broken knife

4. Whether there is dust on the engraving machine tool and the chuck, whether the upper knife is too strong. The chuck and nut are not intact. It is very important that the amount of tool sticking is large. It is often a problem here and it is not taken seriously.

5, the tool problem: mainly related to the hardness, strength, sharpness of the tool of the advertising engraving machine and the length of the special tool extension, the degree of smoothness of the tool rake face. This requires the user to select the correct tool for machining before machining.

6. Whether the materials processed by the advertising engraving machine have impurities and the hardness of the material is too large.

7. Whether the advertising engraving machine is flattened at the bottom of the machine, if it is not leveled, it may cause a broken knife. Whether the spindle motor speed is too low, the spindle motor speed is too low, the amount of knife per tooth per revolution becomes larger, so the cutting force becomes larger, which will cause the knife to be broken. Generally speaking, the spindle speed we use is still high. Some are good.
