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

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

Microcomputer application in auto parts

 

First, implement the procurement of parts according to the parts procurement plan, and then send the unit price, quantity, and total price of all the purchased parts to the computer. Secondly, perform statistics, analysis, and summary according to the inventory of the parts and the current month’s requisition. *The purchase plan of the accessories will be generated afterwards. So it goes back and forth again and again. Handle the usage of the monthly offending parts, calculate the summary of the parts, agricultural parts, and inventory, handle the parts, lend the parts, deal with the waste, dispose of the split rod, mechanically match the parts, and manage the parts. Departments, departments, and special projects are used to calculate the cost of parts used in production and maintenance of each department. Accessory inventory management can randomly query the information of each accessory in the warehouse. The classification of accessories is implemented, and the key management of species funds is achieved. The whole system has gone through many iterations from the development of test applications, feedback, and trimming applications, and has gradually become mature. Taking the unit price item of the material transfer order as an example, we have made a principled change procedure. When designing the unit price of the material transfer unit initially, we directly adopt the user’s usual management method, and the unit price of the material transfer unit is the unit price of the accessory. The unit price in the inventory is calculated and summarized.

After the whole system has been running for nearly half a year, it is found that the inventory quantity of some parts on the inventory report is zero, but the total amount of the parts is not equal to zero. That is, the unit price of the quantity is half the total price. After analysis and demonstration, we found that the unit price of the material allocation order in the original management was considered to be poor, and it was wrong to simply set the unit price of the material allocation order as the inventory unit price. Because the market price fluctuates frequently, the unit price of the accessories we purchase also varies randomly. Even if you buy the same kind of tiles, the price will be high or low, and it is impossible to be unified. In this regard, we need to specialize in the allocation of parts in the program design. The new material, that is, the material that does not exist in the existing warehouse, is newly added this month. The allocation price is the purchase price.
