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 better t

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 of numbers and lette

Elimination of Gear Backlash in CNC Machining Feed System

Elimination of Gear Backlash in CNC Machining Feed System   The transmission gear in the feed system of the CNC machining machine tool must eliminate the transmission gap between the meshing gears as much as possible, otherwise the motion will lag behind the command signal after each reversal of the feed system, which will affect the machining accuracy (accuracy) ). There are the following two common methods for CNC machining machine tools to eliminate the transmission gear gap.   1. Rigidity adjustment method   The rigid adjustment method is an adjustment method that cannot be automatically compensated for the tooth side clearance after adjustment. Therefore, the pitch tolerance and tooth thickness of the gear must be strictly controlled, otherwise the flexibility of the transmission will be affected. This adjustment method has a relatively simple structure and a better transmission rigidity.   (1) Eccentric shaft adjustment method   As shown in Figure 610, the gear 1 is mounted on th

Analysis of Collaboration Relationship in Auto Parts Industry

From the perspective of technological learning and innovation, the auto parts industry cluster has an atmosphere that encourages innovation, and this innovation can be quickly absorbed by other companies in the cluster through technology spillovers, which in turn leads to the emergence of new innovations. The reasons for this phenomenon can be understood from two aspects: On the one hand, because horizontal enterprises in the cluster produce similar or identical products, the differences between them are mainly due to quality and innovation. Faced with internal competition, they will inevitably drive them to continue. Innovation to achieve the purpose of differentiation. On the other hand, the vertical enterprises in the cluster, in order to meet the innovation needs of upstream or downstream enterprises, will inevitably continue to improve and innovate their own products. Moreover, innovation in these two cases is not an isolated behavior. Due to the existence of collaborative relationships within the cluster, different enterprises will choose the way of cooperative development and resource sharing, which will greatly enhance the ability of innovation.

Once the innovation is realized, this innovation will be transformed into explicit or tacit knowledge, and the knowledge learning speed in the cluster is often higher than that outside the cluster, that is to say, through the way of knowledge spillover, this innovation will be quickly Assimilated by other enterprises in the cluster, and continue to innovate on this basis. In this way, an orderly cycle of innovation-learning-innovation will be formed. Overall efficiency advantage. Clusters can maximize the cost savings of recurring expenditures, because industrial clusters can improve and develop the construction of water, electricity, gas and other infrastructures, thereby reducing the cost of recurring expenditures. In addition, enterprises in the cluster have formed a trust relationship through long-term market cooperation and informal communication. This trust relationship offsets the opportunism and uncertainty in the pure market relationship to a certain extent, making the enterprises in the cluster The internalization of transactions greatly saves transaction costs and improves the overall efficiency of the cluster.
