How to use the advertising engraving machine?

1. In the actual processing, the relationship between machining effect and machining efficiency should be fully considered, and the coarse knife, fine knife and three-dimensional engraving can be flexibly applied. Large-area graphic area engraving uses large tools for processing, and small-area graphic areas or The effect of the small tool should be used for fine machining, and the setting of the overlap rate of the tool is also important.

2. Select the processing method according to the processing result requirements-----two-dimensional engraving, three-dimensional engraving or cutting. If pattern engraving is performed, two-dimensional or three-dimensional engraving is selected, and the generated processing path is the engraving path. If you are cutting and machining the wall surface of the sand table model, select "Cutting Word" and the generated path is the cutting path.

3. According to the requirements of processing effect, the path generation method is selected. The two-dimensional path is suitable for plane engraving. The processing effect does not have a strong three-dimensional effect, and the processing fineness is inversely proportional to the processing depth. The three-dimensional path has a "clear angle" engraving action, the processing effect has a strong three-dimensional effect, the processing pattern is fine, the processing fineness is directly related to the fineness of the pattern and the accuracy of the tool parameters, and the processing depth only affects the three-dimensional and does not affect the fineness of the processing. The degree, the greater the processing depth, the stronger the stereoscopic effect.

4. According to the fineness of processing and the texture of the material, choose the engraving processing path form----horizontal milling bottom, vertical milling bottom, forward 45 degree milling bottom, reverse 45 degree milling bottom. These engraving paths produce high processing precision. The processing surface is smooth. The circular path has a fast processing speed and high efficiency, but the processing effect is inferior to others.

5. Engraving tool selection, pay attention to the influence of cutting edge angle and blade width on machining accuracy and progress. If the cutting edge angle and blade width are large, the machining speed is fast, but the machining pattern is not fine, the cutting edge angle and blade width are Small processing speed is slow, but the graphics are fine and the durability of the tool is relatively poor.

How to use the advertising engraving machine without damaging the milling cutter?

1. Whether the power supply provided by the advertising engraving machine is stable, and the unstable power supply will cause the advertising engraving machine to break the knife.

2. Whether the engraving machining allowance is reasonable, whether there is a stepped margin, so that there will be a change in the cutting force causing 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.

3. Check whether the priority mode of the advertising engraving machine is correct. It directly affects the starting speed of the machine. The higher the starting speed, the more likely it is to generate vibration, which will easily lead to broken tools.

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

5. 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.

6. Tool problem: It is mainly related to the hardness, strength, sharpness and length of the special tool, and the smoothness of the tool rake face. This requires the user to select the correct tool for machining before machining.

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.

How to use a knife for advertising engraving machine?

Flat bottom knife

W1: Indicates the tool shank diameter. The commonly used shank diameters are ∮3.175, ∮4, ∮6, which are 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.

The principle of using the knife: use the knife of W2 or A small point when carving small characters, use the big knife as much as possible to increase the processing speed; the tool selection is based on * narrow strokes; 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.

How can the advertising engraving machine extend the life of the spindle?

1. Stop the impact. Violent impact, especially the end of the spindle and the front end cover must not be impacted, otherwise it will damage the precision of the precision bearing and the spindle, resulting in the loss of spindle reversal.

2. Accurate placement and clamping. Before the installation, it should be confirmed that the spindle motor is in a normal state. It is important that the surface is not damaged and the spindle rotates gently.

3. Placement of the clamp cap and cutter. The placement of the tool must cover the reverse rotation accuracy, otherwise it will produce severe vibration, affecting the quality of engraving (milling) and compliance and bearing life.

4, start. For the newly-enabled spindle motor, it is advisable to run at a low speed for the first time, start the first half-speed operation for 0.5-1.0 hours, and then enter the high speed. Similarly, the spindle motor is usually started by the FM voltage regulation method, and efforts should be made to stop the sudden full pressure start. The startup time is about 10 seconds to complete.

5. Run. In normal operation, you should do one, two, three, and even if you stop braking suddenly, the tool card should be shut down in real time when it dies. Listen to the spindle motor running sound with dry friction and strange blame, the invention is very important to check the car in real time; touch the front cover or sleeve heat and vibration environment is stable, if the heat and vibration increase, you should check the car in real time; check the processed parts Whether the quality is stable, such as the change should be shut down in real time.

Careful attention to maintenance is also critical to the choice of engraving machine spindle bearings, which directly affects the life and performance of machine tools or spindles.
