Electrical Chain Saw abnormal heat when charging lithium battery, due to abnormal heat, excluding other factors such as ambient temperature, it is likely that there is a problem with lithium battery. But many users do not take the initiative to touch the lithium battery when charging, so it is difficult to find the problem in time. Because it was not discovered and solved in time, it became a big problem after a long time. Light Electrical Chain Saw batteries are scrapped, you can replace a set of batteries, serious Electrical Chain Saw will also be scrapped, which requires the replacement of a new Electrical Chain Saw and lithium battery. Either way, the cost will increase, which is not what users want to see. So how can you avoid it? Just by knowing the cause, you can better avoid it.
Electrical Chain Saw lithium battery and charger do not match: This problem is very common and easy to be ignored, many users have too much Electrical Chain Saw, so there will be a lot of chargers, because there is no awareness of this, think that it can be charged, think that it is Electrical Chain Saw, but also use to distinguish chargers? In fact, many users have not thought about this problem, each Electrical Chain Saw lithium battery parameters are not necessarily the same, so the charger is not the same. If the charger with different parameters is mixed, it will lead to abnormal battery heating. Therefore, consumers must not be mixed when using, and if the original charger is broken, they must contact the original manufacturer to buy a matching charger, and do not seek cheap.
Charger quality problem: that is, the charger can not be charged normally, do not go to the original charger, and choose a model at will on the market, the price is low, but the quality is not guaranteed, which may also lead to fever.
Electrical Chain Saw lithium battery itself has quality problems: general regular manufacturers rarely appear this situation, of course, even if there will be after-sales. For informal manufacturers, this situation is very common, plus after-sales will not follow up in time.

Brochure printing This is one of the commercial printing and packaging products commonly used by every enterprise in daily product and brand promotion. A good company photo album is not only the specific content of the value of the colorful products, but also the value and grade must be reflected in the brochure printing. For many businesses, finding a good brochure printer can be a headache, especially if you are just setting up a new company. So how can you make the best choice for brochure printing? Here I will share with you some small knowledge that needs to be paid attention to in printing and packaging.
Xiaobian believes that how to print corporate albums depends on the following aspects:
1. Raw materials and colors commonly used in corporate album design:
(1) The master of printing technology and printing knowledge of advertising design masters in the design of albums will pay attention to the following aspects, the majority of the resolution of raw materials commonly used in corporate album design exceeds 300K to ensure the clear expected effect of printing and packaging products. Hue saturation;
(2) Excellent designers generally do not use large ink-base color in the design of corporate brochures, because the printing process of large ink-base brochures cannot guarantee the color bias of the finished products;
(3) In the design of the corporate album, the black font is monochrome black and gray. That way, there will be no overlap caused by inaccurate overprinting in the printed product. Blurry or off-color.
(4) The color value of the computer in the design of the enterprise album is RGB three primary colors, the printed color label value is CMYK, and the color value must be converted from RGB to CMYK security exit when finalized.

drill cnc machine is an automatic machine with high precision and high efficiency. However, in the process of processing, it will inevitably be affected by a variety of factors, making its processing precision produce a certain deviation, and bring some inconvenience to production and life. How to improve the machining accuracy of inclined bed machine tool is a matter of great concern to CNC people.
In the machining process of the machine tool, the precision of the parts processed directly affects the quality of the product, some mechanical parts and precision equipment parts of the processing accuracy requirements are very high, improve the machining accuracy of the CNC machine tool is the key to solve the problem. Through extensive research and analysis, it is concluded that there are roughly the following ways to improve the machining accuracy of CNC machine tools:
First, control the original error to improve the machining accuracy
In the process of drill cnc machine processing, the error itself is inevitable, there is an inevitable error between the machined parts and the CNC machine tool, and this certain error is called the original error. Therefore, in order to improve the machining accuracy of CNC machine tools, controlling the original error of CNC machine tools is one of the important countermeasures. The possibility of the original error should be analyzed systematically, and the corresponding improvement measures should be formulated according to the cause and type of the error.
Second, reasonable design of the core parts of the machine tool to avoid positioning errors
The positioning accuracy of the machine tool has an important impact on the accuracy of the parts, and the core components that affect the positioning accuracy of the machine tool, such as the straightness and levelness of the feed system, guide rail, work surface, etc. When designing CNC machine tools, it is necessary to reasonably choose the core components, such as when selecting the ball screw widely used in the machine tool, the accuracy of the ball screw should be fully considered, and the more mature ball screw technology should be selected and installed.
Third, improve the processing accuracy through real-time monitoring technology
With the continuous improvement of numerical control technology, the drill cnc machine machining process real-time monitoring, timely adjustment of the error in the process of processing, and processing of each link of the error data collection, and feedback to the control terminal, and through the error data to take the corresponding error compensation mechanism, timely error compensation. It can effectively improve the machining accuracy of parts.
