Working principle of slow wire processing

 Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much bett...

Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state.   CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200   beryllium   copper   and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form o...

On the Importance of Ink for Small Character Inkjet Printer

Small-character inkjet printer inks are generally black ink. Black ink is the matching ink for most inkjet printer customers. The reason why it is called ordinary black ink is because it represents the ink used by most of the audience.

The main component of the black ink of ordinary small character inkjet printers is graphite, commonly known as carbon powder. The purity requirement is between 99.998%-99.999%. The particle size is required to be between 0.11-0.12 microns. Exceeding the above indicators will seriously affect the ink splitting window of the printer, and cause various failures in the printer. Not only that, substandard ink will also cause serious damage to the ink system. The most obvious example is the wear and tear on the ink pump, which greatly reduces the service life of the ink pump.

Other ingredients are also strict, such as reducing agents and antioxidants. These two chemical components also require very pure purity for them, even harsh. Therefore, there are not many domestic chemical plants that can provide qualified products. Like Sinopec and PetroChina, these are domestic giants. Only their products can meet the requirements of inkjet printer inks; foreign suppliers are also giants. Like Mobil Oil and so on! Some small manufacturers also produce them. Although the price is cheap, the purity of their products generally cannot meet the requirements.

Compared with the early users’ ink standards for inkjet printers, current customers have put forward environmental protection requirements. *It was developed countries such as the European Union and the United States that made this request earlier. The EU’s ROCS standard is currently the most stringent environmental protection standard, and it imposes almost stringent requirements on printer ink manufacturers. The content of various harmful substances should be controlled within 5ppm. For this reason, inkjet printer manufacturers have invested a lot of research and development expenses to modify existing ink formulas, and a large number of chemical raw materials that meet environmental protection requirements have been used. At the same time, the ink factory has strengthened the production process management to avoid secondary pollution. In order to meet the standards, the factory also purchased a large number of expensive testing equipment, and conducted environmental inspections on each batch of products. For this reason, the cost pressure of manufacturers has greatly increased. In the selection of ink for small-character inkjet printers, Oulance recommends to choose original consumables. Whether it is the price of the inkjet printer or the later maintenance and maintenance of the inkjet printer, the original consumables are the key to reducing the failure rate of the inkjet printer.
