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

Introduction to the importance of trace lubricants

In the application of micro-lubrication system, the generation of oil mist is very critical. There are many factors that affect the effect of MQL micro-lubrication.

At present, most users do not have a clear understanding of the characteristics of oils used under micro-lubrication conditions. They think that as long as the oil can be used in micro-lubrication processing, this is a wrong understanding. It is very important to correctly select micro-lubricating products.

First of all, mineral oil cannot be used in micro-lubrication processing, mainly because the oil mist particles produced by mineral oil are harmful to the human body, and the particle size generated by mineral oil atomization is large, the lubrication effect is not good, and mineral oil is not suitable for high-speed processing Lubrication in the state.

When the micro-lubrication system is used in cutting, the oil is very important. First of all, the oil must be environmentally friendly and should not cause harm to the health of the operators. At present, foreign countries have clear requirements for the oil used in the metal cutting processing field, and the use of MQL technology in the domestic machining field is still in its infancy. Because the micro-lubricating oil is atomized into 0.5-10 micron oil suspended particles, When selecting trace lubricants, the health and environmental protection characteristics of the oil should be considered first.

On the premise of ensuring that the oil is harmless to human health, it is necessary to consider the lubrication and atomization characteristics of the oil in the cutting process. The first thing to consider is that the oil should have a low viscosity. Only low-viscosity lubricants can be used without heating. It is atomized into ultra-fine suspended particles in the micron range, and can realize long-distance transportation without being affected by the high speed of the machine tool. There are many disadvantages of using mineral oil. Firstly, it is difficult to atomize without heating. Even if heated, the atomization effect of ultra-fine particles cannot be achieved. After the atomization of mineral oil, it is not easy to transport long-distance in the small channel, and it is easy to form oil. Droplets, especially affect the transportation in the main shaft, and easily cause oil accumulation in the pipeline, and the terminal lubrication effect is poor. The reason is that the oil mist that forms large particles is affected by the centrifugal force of the machine tool spindle. Compared with cutting fluid, the consumption of lubricating oil is greatly reduced in cutting under the condition of micro-lubrication, and the consumption per hour is below 50ml/h, which is much lower than the consumption of the traditional heating oil mist lubrication system.
