What requirements does advertising engraving machine have for knives
18 Aug , 2020
In the use of advertising engraving machine carving PVC when the appearance of rough edges, what factors caused and solutions;Advertising engraving machine cutting text need to choose the right tool to reduce the damage of cutting products.
1, first check the problem, take a look at the engraving machine spindle speed, normally between 2000-24000 RPM, the spindle speed is too low, there will be burr.
2, the material itself rough edge, normal rough edge we can deal with, if it is a large range of carving rough edge, we should consider the reason of the material, it is recommended to use the regular manufacturer's products, so that the material clearance, quality meet the requirements.
3, according to the different engraving materials should choose the right tool, density board materials generally choose a single blade spiral milling cutter, like acrylic in the engraving should be along with the acrylic lines, to avoid the appearance of burr phenomenon.
4, the problem of the tool, the tool has not been replaced for a long time, the blade wear caused, it is recommended to update and check the tool regularly, to ensure the normal work of the machine.
5, when setting the path parameters, should be set a little more elaborate.Avoid path setting too large, rough engraving caused by engraving burr phenomenon.
6, too much or too small knife will lead to too much knife: too much cutting force, tool deformation is large, resulting in the processed surface is not smooth;Cutting too small: the occurrence of processing slippery phenomenon, resulting in the processing of the surface is not smooth.
7, there is also need to pay attention to PVC board carving is generally counterclockwise knife.
8, the unstable operation of the machine will also appear this phenomenon, it is recommended to check whether there is a loose place.

cutting text need to choose the right tool to reduce the damage of cutting products, how to choose a tool?What are the factors that influence tool selection?
Material factors (PVC and plexiglass);Single blade thread milling cutter is generally used in PVC or less than 5mm thickness of the plexiclass cutting, because this kind of cutter chip removal effect is good, sharp edge, but the hardness is poor, so used to cut like PVC this kind of soft material, when cutting more than 10mm plexiclass will need to use double-edged thread milling cutter.
Material thickness factor;Different materials use different tool lengths, the blade length is 22mm, 17mm, 12mm, 7mm, 6mm, 4mm, etc. Here we need to remind everyone is to choose the tool to generally follow the blade length is about 2mm more than the machining thickness, so that the machine better cutting, cutting quality is better.
Factor of text size;The text size of the different choice of tool diameter is also different, here are several choices of data, optional diameter is 4mm, 3.175mm, 1.5mm, etc., it is recommended to meet the requirements of the R Angle, as far as possible to use the diameter of the tool.
Factors of tool clamping;When installing the tool, the shorter the distance between the knife point and the knife head is, the better. The extra part after leaking the blade should not be more than 2mm. If the tool has a longer clamping, the processing speed should be reduced to ensure the machine
Above for advertising engraving machine factors should be considered when choosing a cutting tool, cutting tool when use to choose the suitable cutting tools, or tools and materials will be damaged, causing waste of resources, reasonable use tool to speed up the work efficiency to avoid unnecessary trouble, the cutting tool in the process of using maintenance should be inspected regularly, to prolong the service life of saving resources.
1, to pay attention to the engraving machine function, engraving machine engraving motor has high power and small power.Some engraving machine power is small only suitable for the processing of materials such as two-color board, building model, small sign, three-dimensional handicraft, etc. This technology has been popular for a period of time, but because the engraving power is too small and greatly affected its application range.
The other is a high-power engraving head engraving machine, this engraving machine is divided into two categories, one is a large scale engraving machine: the format is generally more than one meter, but the precision of this engraving machine is generally poor;The other is the medium size engraving machine: this engraving machine is generally used for fine processing and organic sign making.
Advertising engraving machine is the perfect unity of the two.The combination of high rigid frame and aviation aluminum ensures its stability, bearing weight and strong stability, making the machine run smoothly and durable. The import of high-precision ball screw and linear rolling adjustable clearance guide makes the dynamic accuracy further improved.
2, to understand the performance and function of the engraving motor, the engraving head motor of the engraving machine is also very critical, because the engraving head motor is generally not under warranty, and the engraving head motor is a long time continuous work, so if the engraving head motor is not good will affect the use of the engraving machine.
3, in addition is the engraving head motor speed adjustable range, the general speed adjustable range is thousands to 30,000 RPM, if the speed is not adjustable or the speed adjustable range is small, then it means that the engraving machine application range is very limited, because different materials must use different engraving head speed.
4, engraving machine body manufacturing process: the work of high-power engraving machine requires the body must be precise and stable, so long-term high-power engraving should adopt the casting body to ensure its processing accuracy and stability.
5, the controller is generally divided into two types: one type of controller is only to do the drive, and all its computation work is done by the computer, the computer is in a waiting state when the engraving machine is working, unable to do typesetting work.The other type of controller is controlled by a single board machine or a single chip microcomputer. This controller is actually a computer, so as long as the engraving machine starts to work, the computer can immediately do other typesetting work, especially when carving for a long time, the advantage is particularly obvious.
6, screw and guide is also an important part of the engraving machine good screw and guide is the engraving machine long-term use of its accuracy and performance guarantee.
