Blister light box is a luminous light box composed of LED light bars and acrylic panels. It is characterized by its unique vacuum shape, more attractive than the LED light box symbol on the plane, and more three-dimensional.The blister light box adopts the three-dimensional luminous character processing technology. Due to the stable quality of acrylic, its products are characterized by good light transmittance, clear farsightedness, high compressive strength, colorfast for more than ten years, and bright as new, which are incomparable with other light boxes and metal characters. It is the best choice for businesses with sustainable business and strong strength.
The square Vacuum Light Box is the most common one, which can be used as a blank light box, UV screen, or an inner screen, logo.

In deep hole drilling, traditional lubrication technology uses a large amount of cutting fluid to lubricate and cool. This lubrication method consumes a large amount of cutting fluid and the cutting fluid can be sprayed onto the equipment and the work site, to the environment and the body. It will have an adverse effect. In the cutting process, both the high-pressure cutting fluid and the hard-to-reach machining surface are used, and the cooling and lubrication effects are greatly reduced. The cost of the recovery and treatment of cooling liquid waste is also getting higher and higher, and the problem of the lubrication method of cutting fluid is also more prominent. The mist-lubricated oil mist cooling method is suitable for new types of processing, which can avoid waste oil recovery and pollution problems. At the same time, reliable lubrication improves the surface quality and extends the service life of the drill.
Drills with internal cold holes appear, and the use of oil mist lubrication makes the oil hole deep hole drilling process more reliable. The adapted solution also allows the deep hole drilling micro-lubrication technology to play a better role. The deep-hole drilling micro-lubrication system has been widely used in crankshaft oil holes and engine housings in the automotive machining field.
Deep hole machining is the machining of holes with a ratio of hole depth to diameter of 5 and above. In the machining industry, the machining of holes is more, but in the processing of deep holes, the service life of the drill and the quality of the machining holes are difficult to guarantee. Improving the service life and processing efficiency of drills is the research direction of hole machining. On the one hand, deep-hole machining should select suitable drills to improve processing quality. On the other hand, to select a suitable lubrication system, the ideal lubrication method can increase the life of the cutting tool and the surface quality of the workpiece.
