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,

What are the advantages of CNC turning and milling processing?

cncmachining June 29, 2021


Compared with conventional CNC titanium machining processes, the outstanding advantages of turning-milling combined machining are mainly manifested in the following aspects:

 

(1) CNC turning and milling compound processing manufacturers introduced to shorten the product manufacturing process chain and improve production efficiency. A variety of special tools can be installed, new tool arrangement, reduce tool change time, improve processing efficiency, turning-milling composite processing can complete all or most of the machining procedures in one clamping, thus greatly shortening the product manufacturing process chain. In this way, on the one hand, the production assistance time caused by the change of the installation card is reduced, and the manufacturing cycle and waiting time of the tooling fixture are also reduced, which can significantly improve the production efficiency.

 

(2) Reduce the number of clamping and improve cnc brass machining accuracy. The reduction in the number of card loading avoids the accumulation of errors due to the conversion of positioning benchmarks. CNC turning-milling composite processing manufacturers analyze, at the same time, most of the current turning-milling composite processing equipment has the function of online detection, which can realize the in-position detection and precision control of key data in the manufacturing process, thereby improving the processing accuracy of the product; high-strength integration The design of the machine bed improves the gravity processing ability for difficult-to-cut materials; the machine is equipped with an automatic feeding device, which can realize automatic feeding and continuous, basically realizing the assembly line operation of a single machine tool.

 

(3) Reduce floor space and reduce production costs.

 

CNC delrin machining composite processing manufacturers analyze that the compact and beautiful appearance design improves the use of space, and makes maintenance and repair more convenient, so that customers can get the greatest satisfaction; although the single unit price of the turning-milling composite processing equipment is relatively high, but due to the manufacturing process chain The shortening and the reduction of the equipment required for the product, as well as the reduction of the number of fixtures, workshop area and equipment maintenance costs, can effectively reduce the overall fixed asset investment, production operation and management costs.
