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

Hardware Processing Factory: Process Skills for Surface Processing of Hardware Parts

 Surface processing of hardware parts:

  • 1. Spray paint processing: The hardware processing factory uses spray paint processing when producing large hardware products. By using spray paint processing, the hardware can avoid rust, such as: daily necessities, electrical equipment shells, handicrafts, etc.
  • 2. Electroplating: Electroplating is also the most common processing technology for hardware processing. Through the development of modern design process information technology, the surface of the hardware is electroplated to ensure that the product can be used for a long time without mold and embroidery. Electroplating is common There are: screws, stamping parts, batteries, car parts, small accessories, etc.
  • 3. Surface polishing processing: Surface polishing processing is generally used in daily necessities. Through the surface burr processing of hardware products, for example, we produce a comb, and the comb is a hardware part made by analysis and stamping, then stamped out The corners of the comb are very sharp. We need to polish the sharp corners into a smooth face so that it will not cause serious harm to human health during use.
  • 4. Round surface is the basic method of metal processing, and the equipment used is a lathe. In general machinery factories, lathes account for about 40 of the total number of machine tools. Turning is the main method of rough machining and semi-finishing of various materials, and it is also the final finishing method of various materials that are not suitable for grinding.
  • 5. In the production of small batch products, turning the outer surface can generally be done on a normal lathe. In mass industrial production, hardware processing has extensively studied the use of multi-tool semi-automatic lathes or automatic selection lathes. The design of large disc parts should be analyzed and processed on a vertical lathe. Large long shaft parts need to be processed on a heavy-duty horizontal lathe.
  • 6. The characteristics of turning the outer surface are: simple tool, easy to manufacture, sharpen and install;. The cutting process is stable and the cutting force fluctuation is small, which is conducive to adopting high cutting speed and improving productivity. The machine has good versatility and can be clamped out when processing circles, ends, holes, threads and chamfers. The positioning accuracy between the surfaces is easy to ensure, and it is suitable for non-ferrous metal parts.
