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...
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...

The precision requirements of precision CNC machining parts mainly refer to the precision requirements of size, shape, position and surface, and the surface precision mainly refers to the surface roughness.
Because the CNC lathe has good rigidity, high precision in manufacturing and tool setting, and can easily and accurately perform manual compensation and automatic compensation, it can process shaft parts with high dimensional accuracy. In some cases, it can achieve the effect of turning instead of grinding. In addition, because the motion of the CNC lathe is realized by high-precision interpolation and servo drive, it can process parts with high shape accuracy requirements such as straightness, roundness, and cylindricity.
Because the CNC lathe can complete a lot of processing content in one clamping, it can effectively improve the position accuracy of the parts, and the processing quality is stable. The CNC lathe has the function of cutting at constant linear speed, so it can not only cnc machine parts with small and uniform surface roughness, but also suitable for turning parts with different surface roughness requirements. Generally, the machining accuracy of CNC lathes can reach 0.001mm, and the surface roughness Ra can reach 0.16μm (precision CNC lathes can reach 0.02μm).
Parts with small surface roughness values
The precision CNC machining numerical control lathe has a constant linear speed cutting function, which can machine parts with small and uniform surface roughness values. The problem is that the surface roughness depends on the feed rate and cutting speed when the material, the finishing allowance and the tool have been determined. The cutting speed changes, resulting in inconsistent surface roughness after turning. Using the constant line cutting function of the CNC lathe, you can choose the best line speed to cut cones, spheres and end faces, so that the surface roughness values after turning are small and consistent. .
Parts with complex surface contour shapes
Because the precision titanium machining CNC lathe has linear and circular interpolation functions (some CNC lathes also have some non-arc curve interpolation functions), it can turn complex shapes composed of arbitrary straight lines and various flat curves. Body parts, including list curves that cannot be described by equations that are processed by fitting calculations. As shown in Figure 4-1, the molding surface of the closed cavity of the shell part cannot be machined on an ordinary lathe, but it can be easily machined on a CNC lathe.
