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

Model changes promote the renewal of auto parts

 

Compared with the old Jiefang and Dongfeng Motors, the current models are full of flowers. Although these changes have given people more choices, they have also brought a lot of difficulties to the supply of auto parts. Various models have been replaced many times within a few years, and even a series has several generations, and many of its accessories are not universal.

The supply of auto parts has a huge relationship with the production and operation of the company. Insufficient supply will affect production, excessive inventory, and backlog of funds. In response to these situations, we focus on the market mechanism in our actual work, explore a reasonable balance between the supply and demand of auto parts, and establish a supply and demand mechanism suitable for the market economy and our own characteristics, so that the supply of auto parts can serve the production and operation of the enterprise.

There are many problems in the supply of auto parts for enterprises in today’s market economy. The main manifestations are: poor planning. Now the demand for parts is very unbalanced, mainly due to lack of planning. In the monthly maintenance plan, only the number of overhaul, second warranty, third warranty, and vehicles are indicated. The specific major or key accessories are required to be removed after the vehicle undergoes further training. The degree of damage to the vehicle is reported as a temporary spare parts plan, and these plans cannot be in place at once, or divided into the second and third batches. This adds a lot of difficulty to the procurement work, especially for the parts purchased outside the province. Just longer. Funds are tight. It is not surprising that people owe me and I owe people. The current funds owed by my unit has reached more than 800,000 yuan. Sometimes the urgently-needed parts are provided with good sources, but there is no funds. After all possible means to obtain funds, the sources of goods ran away. The warehouse conditions are poor. Due to the large number of models, the spare parts warehouse is relatively crowded, and the lifting and unloading capacity is insufficient.

The automotive parts and parts machining, PTJ Shop offers the highest degree of OEM service with a basis of 10+ years experience serving the automotive industry. Our automotive precision shop and experts deliver confidence. We have perfected the art of producing large component volumes with complete JIT reliability, backed by the quality and long-term reliability our customers expect.
