Working principle of slow wire processing

by
 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 better t

Hydrostatic guideway of CNC machining lathe

by
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 of numbers and lette

Introduction of KOVAR parts

by
KOVAR parts are commonly used as metal casing materials in the electronic packaging industry. Because they have a linear expansion coefficient close to that of molybdenum group glass, and can produce less sealing stress during the sealing (melting) process with molybdenum group glass, so To obtain good air-tightness, in order to make the metal tube and shell to achieve air-tight sealing, in the entire sealing process, the annealing process undoubtedly plays an important role as a link between the previous and the next. The internal stress generated during KOVAR  machining also prepares the material structure for the implementation of the subsequent process-the sealing process of the metal parts. The main purpose of annealing Kovar shell before sealing is to: (1) Eliminate machining stress. When Kovar undergoes plastic machining deformation during cold working, about 10% to 15% of the applied energy is converted into internal energy, which is commonly referred to as internal stress,

Alternate vehicles, transportation equipment and field work machine oil in all seasons adapt to changes in temperature

cncmachining January 19, 2022

 

Foreign oil companies adopt tracking services for key users. Whenever the oil change period is approaching and users need to buy oil, they will test the oil for free in advance, issue an inspection report, and actively provide key users with a scientific basis for oil change. This kind of thoughtful service not only shortens the distance with users, but also improves the credibility of the brand.

The alternation of the four seasons requires the oil used in vehicles, transportation equipment and field work tools to adapt to changes in temperature, especially in the north. Lubricants of different viscosity grades are usually replaced at the end of autumn and spring, thus forming a peak season for lubricating oil sales. Foreign oil companies attach great importance to the promotional activities in these two seasons. In the autumn, they launched low pour point, low viscosity grades of multi-grade antifreeze and antifreeze, and accompanied the promotion activities to choose gifts that reflect the characteristics of winter; at the turn of spring and summer, they also promote high viscosity grade oils, and there are also optional gifts. Summer characteristics.

Lubricant is a product with high technical content. General users often don’t know the reason for their complicated technical performance, and they don’t know how to choose various brands. For this reason, foreign oil companies often adopt methods such as holding technical exchange meetings, distributing easy-to-understand oil user manuals, and returning visits to answer questions, etc., to conduct extensive and in-depth knowledge marketing.
