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 bett...

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 o...

Plateau construction equipment machinery selection

 

Construction machinery selection of plateau construction equipment must withstand the test of extreme cold and hot plateau hills, swamps and deserts and other extreme geographical conditions. Although the construction machinery of Sweden, the United States and Germany has certain advantages in terms of product quality, work reliability, durability and maintainability, it has no advantage in terms of plateau adaptability compared with China’s military equipment. Therefore, the following aspects should be considered when choosing plateau construction machinery.

Power system selection The output power of the diesel engine decreases with the increase in the altitude and relative humidity of the area in which it is used. The calibrated power of a diesel engine refers to the effective power that can be output at atmospheric pressure, ambient temperature, relative humidity, and altitude not exceeding meters.

Due to low air pressure, thin air, and low oxygen content in plateau areas, the output power of a generally naturally aspirated diesel engine will decrease every meter of elevation, and fuel consumption will rise. When it is above meters, the engine power is only about 5 that in plain areas, and Insufficient fuel combustion produces carbon deposits and emits black smoke, which not only causes early engine wear and pollution, but also pollutes the environment. When the water cooling power is above an altitude of meters, the water cooling power drops more slowly than air cooling. Therefore, the power system of Plateau Machinery recommends using water cooling diesel engines.

Plateau diesel engine power recovery mainly adopts two measures, one is to restore power by boosting, and the other is to increase diesel engine displacement. At present, the diesel engines suitable for plateau work mainly include Chongqing Cummins plateau engine, Germany Doltz turbocharged intercooled water-cooled diesel engine.
