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

What are the expectations of customers for five-axis processing of agricultural equipment

System and technology upgrades have made it possible to complete the five-axis processing complexity requirements of agricultural equipment, so it has gained a strong voice in the current field. In fact, in layman’s terms, the classification of five-axis machine tools includes linkage type and positioning processing type, these types can complete the corresponding processing tasks under the existing technology and have the characteristics of complementary advantages.

1. Meet the needs of complex development

Complex development needs can be seen not only in the field of five-axis Cnc Machining of agricultural equipment, but even the cultivation of talent needs is closer to the direction of cross-shaped talents. Therefore, the expectations of customers in this area are a major development theme in today’s era. Only by conforming to the needs of the times to realize the transformation of functions and technologies can we stand in a more favorable position in the increasingly fierce market competition.

2. Expand the scope of the process

After a new round of upgrade tests, experienced agricultural equipment five-axis processing manufacturers are able to summarize and master the market demand to a certain extent. For more special requirements, they can also be gradually completed through process adjustment and optimization, and find out how To obtain better cutting efficiency and effectively avoid interference effects, this processing mode gives more possibilities to expand the process range, can meet the needs of the market and successfully avoid many technical misunderstandings.

2. Improve processing quality

The use of numerical control code technology to effectively keep the trajectory of the tool center point within the set range is a major feature of the five-axis processing of agricultural equipment that everyone praises, so the overall processing quality can be controlled by the code and parameter settings , The quality control of this processed product has been guaranteed to a large extent, and customers can also wait for receipt with confidence.

The five-axis processing of agricultural equipment has also benefited from the development, at least it will increase its own bargaining chips in addition to providing good services to customers through technological improvements. From the perspective of technical difficulties, a very important part of processing in this field lies in the setting and calibration of machine parameters. It is necessary to clearly grasp how to control the parameters in order to obtain the finished product that the customer wants. This problem requires experience and technology. It can only be achieved by background operators.
